Ariston Hotpoint washing machine displays error n20 - how to fix the problem. Error H20 in the Indesit washing machine: what to do and how to cope?

During operation of the Indesit washing machine, error code H20 may appear.

Often the problem occurs soon after startup, and it is associated with incorrect water supply, but sometimes the problem turns out to be more complex, and then it may not be possible to fix the problem on your own.

What the error code H20 of the Indesit washing machine means and how to fix the problem, we will tell you in the article.

Error interpretation

Error h20 in the Hotpoint Ariston washing machine can occur in each of the programs, as a rule, it occurs after 10 minutes of operation. Characteristic signs are the lack of water entering the tank at all or in a very small amount, or, conversely, in an excessive amount. It is also possible that water is collected and drained endlessly.

The most common malfunction occurs at the rinsing or spinning stage. But, if you run the Drain or Spin programs separately, the program will run without failures, this is a distinctive feature of the H20 code.

If your Ariston Hotpoint machine produces this code, it means that there is a malfunction in the fluid filling unit.

Reasons for appearance

At the start of work, the machine may freeze and display the message “ash 20” literally in the first minutes after starting.

The reason for the error code may be one of the following situations:

drawing too much water;
taking too little water;
complete lack of recruitment;
non-stop set.

Less often than at the beginning of the program process, such a failure code occurs at the stage of rinsing clothes. In addition, it may not always appear, but only in certain modes, or it occurs unsystematically, when the pattern is almost impossible to trace.

In some cases, the H20 message is issued in combination with other errors, for example, with F08 or F01. In such a situation, you first need to eliminate them as the root cause of the malfunction .

Frequent breakdowns

Most often, clients ask us to fix problems related to the fact that the machine:

Does not drain water - stops when working with a full tank. The problem is probably a clogged filter or pump failure. There is no water drainage either constantly or from time to time. It is enough to clean or replace the filter; when the pump has been in use for more than 5 years, it is replaced with a new one.
Humming/noisy noise when spinning – sounds like a jet plane taking off should alert you. The reason is usually bearing wear, which is inevitable over time. It is advisable to replace parts if the design of the washing machine allows it.
Doesn’t draw water - check the water supply, the presence of cold water, whether the tap is turned off, whether the door is closed or not. The problem occurs due to a malfunction of the heating element, the inlet valve.
Doesn't heat the water - a common problem. Place your hand on the door, if the glass is warm 20 minutes after start, the heating element is working, if not, check it. The machine may be displaying an error code.
Indicators are flashing - there is a problem with the control module. Appears as a result of sudden changes in mains voltage. If the machine stops during washing, washes for too long, the spin cycle does not work, or the automatic circuit breaker (RCD) knocks out, check the control module. Usually complex repairs help - soldering microcircuits, flashing.
The drum does not spin - the problem is overload or the drive belt. The weakest models in this regard are Samsung and Indesit.

The machine does not turn on, leaks, vibrates a lot, does not wash at all, or the door does not open? A comprehensive diagnosis and appropriate repairs are required. To repair equipment at home in Moscow, call a specialist.

Fill valve failure

If cleaning the filter mesh does not bring results, then to eliminate error H20 you should check the condition of the fill valve of the Ariston machine. To do this you need to do the following:

Remove the top cover of the Ariston washing machine.
Find the required unit and, using a multimeter, diagnose the contacts and wires. They could have been damaged by vibration of the device or damaged by mice or rats living in the house.
Diagnose the Ariston unit itself.
If it is faulty, disconnect the sensor from the contacts and disconnect it from the device body.
To eliminate code H20, purchase a new drain valve and install it.

Causes of error H20

This code indicates that the washing machine is unable to obtain the amount of water required for the washing process over a certain period of time.

There are several main reasons:

Perhaps the tap is turned off or there is simply no water in the water supply or there is not enough pressure. Experts note that most owners of washing machines do not check the availability of water from the tap. There may be another problem - improper angle of inclination of the hoses. To verify or rule it out, check the washing machine installation instructions.
It is necessary to clean the coarse mesh installed upstream of the fill valve. To do this, unscrew the inlet hose, then, using pliers, carefully remove the mesh and rinse it under running water.

Important! You can also soak the filter for a quarter of an hour in a container with a solution of citric acid, this will remove not only debris, but also lime deposits. You can take a more thorough route and perform all the cleaning procedures described in the article on washing machine prevention at one time.

The malfunction may lie in the fill valve itself.
It is necessary to check the drain hose coming out from the bottom of the Indesit machine. In a washing machine, error h20 occurs when both the hose and its entry point into the sewer are located low from the floor. Remembering the principle of communicating vessels, it is easy to understand why the flooded water immediately flows into the sewer pipe. To eliminate this problem, it is enough to fix the hose to specially designed mounts on the back of the device. The highest point of the hose should be placed almost on the top of the machine.

Important! If the drain hose is not long enough for this attachment, it can be extended. To do this you need another hose, an adapter and two clamps. To do everything correctly, follow the more detailed instructions set out by our specialists regarding the arrangement of draining water into the sewer.

The simultaneous activation of the fill valve and drain pump is also possible due to problems with the electronic control module.
The reason may lie in a clogged pump filter.
The pipe needs to be replaced or cleaned.
There is a foreign object in the drain hose.
Small foreign objects may become lodged in the pump itself.
A blockage has formed in the sewer or siphon.

Important! To figure out how to clean the filtration system and water pipes of your washing machine, use our recommendations from the article “Hose for a washing machine.”

The machine does not fill with water

If the washing machine does not draw water or draws in only a small amount, this may indicate a lack of liquid in the water supply or a closed water supply tap at the inlet, as well as a slight pressure, which may be caused by a partially open valve. To eliminate error H20, you need to turn the tap completely and make sure there is water in the water supply system.

The second reason for error H20 is a clogged filter in the filling valve of the Ariston washing machine, located behind the hose supplying water to the device. It is installed to prevent particles of debris from the plumbing system from entering the Ariston device. To fix the problem that caused error H20, you need to turn off the water, disconnect the inlet hose of the Ariston device and, armed with pliers, carefully pull out the filter mesh.

To clean it, you need to rinse it under a strong stream of running water, and if the dirt is very strong, you can place it in a citric acid solution for 15-20 minutes. This procedure will remove not only debris, but also limescale. After processing, the mesh must be installed back, the hose connected and the water supply turned on.

Filling and subsequent drainage of water

If an Ariston machine fills with water and immediately drains it, and error code H20 is displayed on the screen, this may indicate that the drain hose is connected to the sewer much lower than necessary or has fallen out of the fasteners on the back wall of the device that held it in vertical position.

To troubleshoot an Ariston washing machine that causes error H20 to appear, you need to lift the middle of the hose and secure it above the tank level; for this, a special holder is included with the washing machine. If it falls out of the latch at the back, you just need to put it back.

There may also be situations where the pump filter or the pump itself, drain hose, siphon or sewer becomes clogged. All these elements of the Ariston washing machine also need to be checked.

If error H20 appears for the first time on Ariston washing equipment, this may indicate a failure in the control board or in the device display. To eliminate error H20, you need to unplug the washing machine from the socket and plug it back in after 20-30 minutes. This “reboot” of the device can help in this situation.

If the above methods did not help resolve the H20 error, this indicates more serious problems in the washing machine.

Fill valve failure

If cleaning the filter mesh does not bring results, then to eliminate error H20 you should check the condition of the fill valve of the Ariston machine. To do this you need to do the following:

Remove the top cover of the Ariston washing machine.
Find the required unit and, using a multimeter, diagnose the contacts and wires. They could have been damaged by vibration of the device or damaged by mice or rats living in the house.
Diagnose the Ariston unit itself.
If it is faulty, disconnect the sensor from the contacts and disconnect it from the device body.
To eliminate code H20, purchase a new drain valve and install it.

Water level sensor malfunction

The filling of the required amount of water during washing is monitored by a pressure switch or, in other words, a water level sensor. It transmits data to the control module of the Ariston machine about how much water has been collected. If it is not working correctly, the device may draw very little or a large amount of water, resulting in error H20 appearing on the screen. You can check the condition of this sensor yourself, you just need to know what to do.

To diagnose the condition of the water level sensor of the Ariston washing machine, you need to perform the following steps:

Remove the top cover of the Ariston washing machine.
Find the sensor of interest at the top of the device.
Make sure the pressure tube connection is tight. If it is disconnected or clogged, this will affect the operation of the pressure switch, which means it needs to be cleaned and installed in its original place. If it is torn, it must be replaced.
Using a multimeter, you need to check the contacts of the pressure switch and the wires leading to it.
If the cause of error H20 is not detected, this indicates a malfunction of the sensor itself, which happens very rarely. In this case, you need to purchase a new pressure switch and install it in place of the non-working one.

Ariston machine electronic board

If everything is also in order with the pressure switch, then to eliminate error H20, you should diagnose the electronic board of the Ariston washing machine, which controls the operation of the entire device. A triac or other elements in the water inlet valve control circuit could have burned out. The tracks of the microcircuit transmitting the command or soldering of the elements could also be damaged. In the rarest cases, the controller processor could break down or there could be a failure in its firmware.

You can fix these problems yourself with a soldering iron and a new element, but it is better to call a specialist and entrust the repair of the Ariston washing machine to him, so as not to cause even more damage to the washing machine.

Thus, if error H20 is displayed on the screen of the Ariston washing machine and any problems occur, this indicates problems with the water supply or drainage system.

To eliminate error H20, you need to check how the water is supplied, clean the inlet valve strainer, and also make sure that the drain hose is not clogged and is correctly connected to the sewer.

If the malfunction has not been resolved, you should check the condition of the fill valve and water level sensor of the Ariston washing equipment, and if this does not help, then diagnose the electronic board.

If the user can eliminate the simple causes of error H20 on his own, then to check the main components, it is recommended to contact a service center and call a specialist, especially if you are not sure that the repair will be completed successfully on your own.

Wear of machine fasteners

Operational problems can also arise when the mechanical fasteners on the machine become loose or broken.

Most often, this is expressed in weakening the fixation of the machine hatch. The problem has the following symptoms: strong noise during operation of the washer and characteristic vibrations.

To get rid of this, just tighten or completely replace the fasteners with new ones.

Problems with drum rotation

Another problem that can cause the machine to stop working is the drum not rotating.

There are several reasons that can cause such a situation: engine failure; problems with electrical wiring; collection in the operation of the control panel or clogged filter. However, the most common cause is wear or excessive stretching of the belt.

In this case, you need to replace it - there shouldn’t be any special problems with replacing it yourself.

If the reason is different, then it is best to call a professional to your home to identify the cause of the machine breakdown.

How to resolve the H2O error

H2O is a common error with any model of Indesit washing machines, so it is better to immediately understand the reasons for its occurrence in order to ensure comfortable operation of the equipment.

If the reason is in the hose, described above, then solving the problem does not require repairs and calling a specialist; you can handle it on your own.

While simultaneously draining water from the system

To cope with a breakdown, you need to mount the hose correctly - it is hung on special mounts provided by the manufacturer on the rear wall. As a result, the highest point of fastening is almost at the top of the CM.

If the hose is not long enough, you should lengthen the tube. What should I do to extend the hose? To do this you will need a second hose, an adapter and 2 clamps.

If everything is done correctly, but during the next wash the H2O light is still on, then the reason was not only in the hose - perhaps the control module, pump or other SMA unit has failed.

H2O error - what to do next

When an Indesit brand washing machine displays an H20 error, you don’t have to rush to call a technician - in many cases you will be able to fix this problem yourself. Fault codes were invented by the developers to prompt the user:

The water is blocked. It is necessary to check whether the valve supplying it to the SM is closed. In the case of a closed tap, water does not flow at all, but if it is slightly open, it flows too slowly. Then the display also shows an error.
There is no water in the plumbing system. If this is the case, the error did not appear due to the fault of the machine, it is worth solving the problem with the water supply - call a plumber.
The pressure in the pipeline is too low. If the pressure is low, the water takes a long time to fill and the H2O error appears. The problem should be looked for in the water supply, not the washing machine.
The water inlet filter is clogged. This mesh tends to clog over time, which prevents the normal flow of water into the system. To clean the inlet hose, you need to unscrew the filter and rinse it thoroughly. You can put a solution of citric acid in it for a quarter of an hour, which will remove limescale.
Failure in the control module (board). If H2O appears for the first time, there may be a malfunction in the display or control panel of the SM. Reset the error by unplugging the machine for 10 minutes. Take care of electrical appliance contacts, which deteriorate in high humidity indoor conditions. Perhaps dehumidifiers and good ventilation will save washing machine parts.

If none of the methods described above helped, and the H2O error appears again at the rinsing stage or during washing, then it is best to contact a technician or service center with this question.

Troubleshooting algorithm

Let's look at what to do in each specific case:

If the problem is a locked tap, you just need to open it. And the problem with pressure can be solved by contacting utility services, or running the program when water consumption is lowest (late in the evening or, conversely, early in the morning).
Then check the condition of the mesh filter; it is located where the inlet hose connects to the machine. If it is clogged, clean it.
Also check the place where the hose connects to the sewer; it may be kinked or located below the level of the tank, which prevents the normal outflow of liquid.
If a problem occurs with the control board, you will have to send it for diagnostics, after which you will need to reflash it or purchase new elements.
There is a problem with the fill valve, you need to buy a new one.
The liquid level sensor does not take readings correctly, this is either due to the fact that the intake chamber is clogged, clean it. The pressure switch is disconnected or clogged, inspect and, if necessary, replace. If the sensor itself is faulty, then it will need to be replaced with a working one.

The wiring in the filler valve chain is damaged, call this section. If a break is detected, clean the area and solder; if this is not possible, remove the damaged section of the circuit and connect a good one.

Filling and subsequent drainage of water

There may also be situations where the pump filter or the pump itself, drain hose, siphon or sewer becomes clogged. All these elements of the Ariston washing machine also need to be checked.

If the above methods did not help resolve the H20 error, this indicates more serious problems in the washing machine.

Breakdowns requiring major repairs and replacement of parts

If, after preliminary testing, the washing machine displays a fault code of type H20, then you should check step by step:

To carry out diagnostics, you will need to disconnect the equipment from the water supply and sewerage systems. To gain access to the components, it is necessary to partially disassemble the housing. You will need a set of screwdrivers and wrenches. If the owner does not have the skills to repair household appliances, then you need to contact a service center. The average price of service in the central regions of the Russian Federation (as of mid-2022), excluding the cost of purchasing spare parts, is shown in the table.

Type of repair work	Starting price, thousand rubles.

The water inlet valve is faulty

The water supply inlet hose is installed on the valve fitting with an electromagnetic drive, which allows you to regulate the flow intensity. If the coil is shorted or broken, or the stem is stuck due to corrosion, the valve becomes inoperable. Some Hotpoint Ariston washing machines use a valve with 2 actuators. If such a unit breaks down, the equipment does not draw water in the washing or rinsing mode. It is impossible to restore the mobility of the rod or a damaged coil; repair consists of installing a new valve.

The pressure switch is faulty

A malfunction of the pressure sensor leads to an increased level of liquid in the tank and continuous operation of the pump. The cause of the defect is debris that has entered the working chamber of the sensor or clogged the measuring tube (possible damage to the hose or fitting). The repair consists of cleaning the working chamber and hose from deposits and installing the part in its original place. It is possible to replace the tube with a hose with identical geometric dimensions. If the measures did not allow you to restore functionality, then it is necessary to install a new sensor.

Problems with the electronic controller

The control unit, located in the upper part of the equipment body, regulates the water supply depending on the operating mode. If the electronics do not work correctly, the machine does not take in water (with normal pressure in the pipes and a working valve) or pumps in an insufficient volume of liquid. If the software fails (for example, due to a power surge), it is enough to turn off the power for 10-20 minutes. The controller's memory is cleared and functionality is restored.

If the error reappears, remove the housing lining and inspect the printed circuit board. No peeling of tracks or oxidation of electronic components is allowed. If defects are detected, the unit must be repaired at a service center. For example, a triac that controls the operation of a water inlet valve often fails. If restoring the unit is impossible, then purchase a working controller removed from a washing machine of a similar model.

Damaged wiring or contacts

Polymer is used to protect electrical wiring harnesses. This material is damaged by rodents (a common problem in the private sector). The layer is also destroyed under the influence of external mechanical loads. It is necessary to inspect the fill valve circuit cable and look for exposed areas. The cause of the defect may be oxidized contacts. The technician needs to clean the contacts and restore the insulating layer (with polyvinyl chloride tape or heat shrink tube). If repair is impossible, then purchase a new harness or assemble a wiring bundle with your own hands.

Water level sensor malfunction

To diagnose the condition of the water level sensor of the Ariston washing machine, you need to perform the following steps:

Remove the top cover of the Ariston washing machine.
Find the sensor of interest at the top of the device.
Make sure the pressure tube connection is tight. If it is disconnected or clogged, this will affect the operation of the pressure switch, which means it needs to be cleaned and installed in its original place. If it is torn, it must be replaced.
Using a multimeter, you need to check the contacts of the pressure switch and the wires leading to it.
If the cause of error H20 is not detected, this indicates a malfunction of the sensor itself, which happens very rarely. In this case, you need to purchase a new pressure switch and install it in place of the non-working one.

Bottom line

Thus, if error H20 is displayed on the screen of the Ariston washing machine and any problems occur, this indicates problems with the water supply or drainage system.

To eliminate error H20, you need to check how the water is supplied, clean the inlet valve strainer, and also make sure that the drain hose is not clogged and is correctly connected to the sewer.

Indesit n20 washing machine error Leave a comment

Indesit electronics are capable of independently testing the washing machine, performing diagnostics and indicating a malfunction. Users often encounter error n20. what it signals and what to do .

Displaying error h20 on an indesit washing machine

If h20 appears together with another code (for example, F01 or 08), this is the reason.

Error H20, what does it mean?

Before starting repairs yourself or asking a workshop for help, it’s worth finding out what error H20 means. In a general sense, this message indicates that there are problems with the flow of water into the drum. Essentially, H20 means that during the time allotted by the program, the device did not have time to collect the required amount of water. There are several reasons for this phenomenon.

The tap that controls the water supply to the Indesit washing machine is closed, or there is simply no water in the water supply.
The inlet filter, the mesh located in front of the machine valve, is clogged.
Problems with the mechanical part of the valve.
The intake valve solenoid coil is burnt out.
The wiring is damaged, the integrity of the conductors going from the control module to the valve is compromised.
Incorrect operation of the control module caused by damage to the electronic components of the circuit.

Sometimes error H20 appears not alone, but “in company” with other errors, most often these are: F08 or F01. In this situation, H20 is not a malfunction, but only its consequence. To correct the situation, it is necessary to eliminate the causes of other errors in the Indesit washing machine; most likely it will go away along with them.

Having figured out what the H20 error code means, you can move on to correcting the situation. There seem to be two options for solving the issue: you can call a technician, or you can try to repair the Indesit washing equipment yourself. Whatever path you choose, before taking decisive measures to eliminate the H20 error, it is worth performing a few basic operations, namely, checking whether the water is suitable for the device.

What to do if the Indesit washing machine displays error H20?

During operation of the Indesit washing machine, error code H20 may appear.

What the error code H20 of the Indesit washing machine means and how to fix the problem, we will tell you in the article.

What if everything is simple?

According to statistics, in the vast majority of cases, error H20 on the display of an Indesit washing machine has nothing to do with the failure of components or assemblies. The main reason for its appearance is the banal lack of water in the water supply.

That’s right, before calling a technician or disassembling the Indesit machine in search of a broken part that caused the H20 error, you should make sure there is water in the system and its pressure is sufficient. If there is no water at all or the pressure is too weak, simply postpone the wash until the water supply parameters normalize.

The same effect is achieved by a faucet that is closed due to forgetfulness or is broken, cutting off the water supply to the device. Everything is also simple here, to eliminate error H20 you just need to provide a water supply and restart the washing program. Most likely, the H20 error will disappear.

Weak pressure

The reasons are:

partially closed tap on the cold water supply pipe;
damage to pipelines due to an accident or connection of equipment with increased water consumption;
reduction in the flow area of pipes due to the formation of a layer of rust or the ingress of large fragments of dirt.

Filter clogged

There is a mesh filter at the inlet of the washing machine valve that separates large dirt particles. When the element becomes clogged, the water pressure drops. To repair, you will need to close the valve and then unscrew the hose nut. The mesh must be washed with water and cleaned with a soft brush. To remove salt deposits, use a solution of citric acid. It is not allowed to operate the equipment with a removed or torn filter, since dirt particles jam the moving element of the valve.

Self-draining water from the drum

According to factory documentation, the drain hose should be located above the liquid level in the tank. There are hooks on the rear wall of the housing for attaching the hose. If the clamps are broken and the pipe lies on the floor, then the water spontaneously drains.

The pump tries to pump fluid for a long time, and then an error appears on the display.

In this case, you need to lift the hose onto standard hooks or make your own clamps that are attached to the wall surface with screws or 2-sided adhesive tape.

Control or display board failure

The display of the code may indicate a failure of the firmware written to the controller’s memory. To reset, you need to disconnect the equipment from the network for 10-20 minutes; after turning it on, the problem does not recur. The cause of the defect may be an increased level of humidity in the room. Condensation settles on the electronics and disrupts the normal operation of the control unit.

Incorrect drain connection

The drain hose should run along the back of the machine and then into the sewer. The installation diagram is indicated by the manufacturer in the instructions; kinks and twisting of the hose increase the flow resistance. Liquid remains in the drum, causing an error code to be displayed.

Lack of water in the device

There are valves on the water mains. When partially or completely blocked, the supply of liquid to the washing machine tank is disrupted.

To check, open the mixer tap. If there is no pressure, then it is necessary to check the valves.

Another cause of the defect may be a complete shutdown or low pressure of the liquid in the water supply lines due to an accident.

Software glitch

In some cases, the Indesit washing machine displays error H20 due to a random software failure. This happens even with new and perfectly serviceable units. The procedure to follow if you suspect a control module error is as follows:

The washing unit is switched off.
The cable of the machine is completely pulled out of the network and the device is left de-energized for 15 minutes.
After the time has elapsed, Indesit is connected back and the washing mode is started.

In some cases, it is necessary to repeat the reboot 2-3 times in a row to achieve the result. If the failure eventually goes away and never returns, the problem can be considered resolved.

In this case, you need to pay attention to the level of humidity in the room, the quality of the supplied voltage and the degree of vibration of the Indesit machine during operation. Typically, software failures occur due to inappropriate external conditions. If the washing unit continues to operate under high loads, new and more serious breakdowns may soon appear.

It is better to connect the washing machine in the bathroom through a special socket with moisture protection

Diagnosis and correction of Indesit washing machine failure

An H20 message is not always a reason to call a repairman. In most cases, you can restore normal operation yourself.

The reasons for the failure may be the following situations:

lack of water in the supply system;
clogged water supply filter;
violations when connecting the washing machine to communications;
failure of the pressure switch;
disruption in power supply;
control module failure.

Lack of water in the system

The reason could be either a complete shutdown of water in the house or a closed water supply tap to the washing machine. If the valve is closed or not fully open, it must be moved to the working position.

In these cases, as well as in the complete absence of water in the system, H20 is not a signal that the washing machine is broken, and it can be started later.

Fill valve strainer clogged

The filter is installed in front of the valve in the area where the water inlet hose is connected . The filter is a plastic mesh that is designed to catch debris that may be present in tap water.

Over time, as a result of long-term use of the Indesit washing machine, the mesh may become so clogged that the water supply becomes either very weak, or its supply is completely blocked. Cleaning the unit will solve the problem.

Work algorithm:

Disconnect the inlet hose from the washing machine.
Remove the filter using pliers.
You can simply rinse the removed part in water under the tap.
Install in its original place.
Connect the hose.

After the mesh has been removed and washed in water, the filter can be further treated in a solution of citric acid. This will help to perform better cleaning and remove lime deposits.

Procedure:

pour 0.5 l into a bowl. water;
dilute a tablespoon of citric acid;
place the part in a bowl;
leave for 20-30 minutes;
Rinse.

The video will show you how to clean the inlet hose filter of an Indesit washing machine:

Fill valve failure

The fill valve is a part that is responsible for drawing water into the machine. If it fails, it is replaced with a new one .

Incorrect drain connection

In cases where the machine fills water continuously, it is necessary to check how the drain is organized in the washing machine, and whether water is spontaneously discharged into the sewer.

Otherwise, the water will simply flow into the sewer . The washing machine will constantly add water to compensate for the loss of water. The result is an H2O error on the display. To correct the situation, the drain hose should be positioned in an elevated position. After this, a short washing mode without laundry is started and the operation of the device is monitored.

Installation of the Indesit washing machine and connection of communications must be carried out according to the instructions, strictly in accordance with the manufacturer’s recommendations.

Malfunction of the control unit

The H2O code may be associated with a malfunction of the control module. This part is located at the top of the washing machine. If H2O appears for the first time, you can try to reboot.

To do this, perform the following actions:

Unplug the washing machine by unplugging the plug from the socket.
Wait 20 minutes.
Plug in.
Turn on the machine.
Select a short program.
Start the cycle.

If the washing machine began to operate as normal, the failure was probably accidental. Otherwise, it is necessary to carry out a complete diagnosis of the control circuit. A specialist who repairs washing machines can do this kind of work efficiently. He has the necessary skills and tools.

Breakdown of the pressure switch

The pressure switch transmits a signal to the control board about the amount of water collected . This part is located under the top cover of the washing machine. To analyze the condition of the part, the sensor is removed by disconnecting it from the pipes and wires.

Power supply interrupted

Unstable voltage in the network and wear of parts can lead to various failures , including the appearance of an H2O error. The cause may be either burnt out contacts and wires, or mechanical damage, for example, mice gnawing on wiring in a private home.

It is possible to check the condition of the wires by partially disassembling the washing machine. If a wire break is visible visually, the defect should be eliminated. Burnt contacts are replaced.

Unstable voltage in the network is one of the reasons for failures of the washing machine components, including the control board.

Problem with Indesit machines

A washing machine of this brand may not draw water due to the following reasons:

Impossibility of water flowing into the machine: the tap that supplies water is turned off, there is no water in the riser. It may be that there is water, but the mesh that removes hardness from the water is clogged or the fill valve is faulty.
This error can occur in Indesit washing machines even when water enters the drum, but is immediately drained. Usually the water flows down the drain, but the machine may have a serious leak.

Even with washing machines it doesn't look any better at the moment. The company has responded globally and will likely have to write off the entire product. Under the radar - because the product was not that interesting - a significant problem also arose in the production of washing machines. Photos from another Texas client even show impressive stains on a basement wall.

In said vibrations, but it's probably more than a little violent twitching. Meanwhile, a number of consumers from three states joined forces to form a class action lawsuit. Mine for household appliances, including many washing machines.

electrical circuit repair – from 1,500 rubles;
repair of the control board - 2,000 rubles or more, etc.

Upon completion of the repair, the technician tests the performance of the washing machine and gives a guarantee for the work performed.

Outdated models

Error codes for Hotpoint-Ariston washing machines will be the same as for Indesit equipment, since the equipment is produced by the same company. If there is no information display, you need to look at the dashboard. Failure F03 corresponds to a signal from the power indicator, repeated three times, and the programmer knob will rotate to the right.

This is true for models of the Margherita series. In them, it is the power-on indicator and its signals that serve as the main source of information - how many times the LED blinks, such a code will have to be deciphered.

EVO-II

In EVO-II series models without a display, the main indicators of wash program failure are the spin, delay timer, super wash, quick wash and extra rinse LEDs. Based on their signals, a breakdown is determined. For example, blinking of the additional rinse sensor indicates a short circuit (error F1). The damage should open the power circuit between the motor and the controller.

If the quick wash button flashes briefly, the problem is again in the motor - error F02 has been diagnosed. It is due to the fact that the engine does not rotate. The combined blinking of the diodes corresponding to the extra rinse and quick wash indicators is the already familiar error F03. You need to check the temperature sensor.

Sometimes signals are given by 3 elements at once. If the super wash, quick wash and extra rinse indicators light up at the same time, you can diagnose error F07. It means that the water in the tank is not heated by the heating element - it has failed and requires replacement. When the timer light and the quick wash signal blink at the same time, we can talk about an error coded F10. You will have to check the wiring contact with the water level controller, and if necessary, replace or repair damaged circuit elements.

Failure code F11 in the case of a light indication looks like a combination of flashing timer lights, quick wash and additional rinse. Such damage cannot be detected without a multimeter - the problem is in the pump. If the problem is not a broken wiring, the entire pump must be replaced.

Aqualtis

Of course, the indication appears differently in different series - the older the model, the more difficult it is to find information about its encoding. Usually the manufacturer indicates the main codes in the instruction manual, but there may be discrepancies here too. For example, in Aqualtis, failure indicators correspond to heating temperature sensors (F16 - 60 degrees, F8 - 50°C, F4 - 40°C, F2 - 30°C, F1 - cold). By adding up the total values of the flashing elements, you can get the current error code.

Recommendations

will help you solve problems with your washing machine :

If you have no experience in repairing household appliances, undertake independent diagnostics and troubleshoot complex elements of the device. For example, a control module is not worth it.
If tap water is of poor purification quality, it makes sense to install a filtration system directly at the entrance of the pipes to the apartment. This will prevent residue from getting into the washing machine.

Adviсe

Indesit brand washing machines, like any other equipment, can fail. One of the most common malfunctions in their operation is the appearance of error H20 on the display. To maximize the service life of equipment and prevent such problems, experts recommend adhering to simple rules.

After purchasing a washing machine, its installation and connection should be entrusted to specialists. The slightest mistake when connecting to the water supply and drainage system can cause error H20 to appear.
You need to start washing by checking the presence of water in the system. When finished, turn off the water supply and wipe the drum dry. The choice of washing mode should be chosen strictly according to the instructions in the instructions supplied with the equipment by the manufacturer.
Periodically you need to clean the filter and the tray where the washing powder is poured. It is advisable to do this after every fifth wash. If plaque appears on the filter mesh, it should be cleaned with special detergents.
It is strictly forbidden to overload the drum - this puts additional load on the motor and leads to damage to the water level sensor, after which error H20 appears. You should not frequently wash things at maximum temperature - this will shorten the service life of the equipment.
If there is a problem with the water supply in a house or apartment (low pressure), it must be eliminated before installing the equipment. Alternatively, you can connect a small pumping station to the water supply system.

Preventive measures

To reduce the likelihood of an H2O error code appearing on the display, it is recommended:

Do not turn on the device if the water in the system is dirty after repairs to the water supply system and contains rust particles and other contaminants.
The washing machine must be connected according to the manufacturer's instructions.
It is necessary to organize the operation of the washing machine in such a way that there are no power surges. A special device, a voltage stabilizer, can help with this.

What to do and how to fix a malfunction in an Indesit washing machine with error n20

Why are there problems with water intake?

If an Indezit Iwsd, Wise or any other model of the brand draws water with a characteristic long murmur, while the drum spins for five to seven minutes, then stops, then the washing machine will certainly freeze after a few seconds, and the display will show the code h20. In this case, there may be either too much water, too little, or the supply is continuous. It can also occur in the rinse mode during a normal wash program.

The tap located at the connection point between the tap water and the inlet hose is not open.
Strainer is clogged.
Mechanical or electrical damage to the fill valve.
Defects in the wiring going to the water inlet valve.
Malfunctions of the electronic control board affecting communication between the module and the valve.

Indesit washing machine: error h20, what to do?

Water inflow

If all the valves are open, the plumbing system is in order, there is water, its pressure indicator is normal, but for some reason it does not get into the washing machine. But you shouldn’t immediately start “internal repairs”; perhaps the cause of the malfunction lies in a banal blockage.

What to do to fix the problem:

Turn off the water.
Disconnect the inlet hose.
Rinse it thoroughly several times.
It is also good to rinse the filter mesh, which is located in the lower part of the housing, in the place where the water intake pipe itself is screwed in.
It would be a good idea to clean the intake valve itself. To do this, turn off the machine and remove its top cover. Unscrew, disassemble and carefully clean the required part.

Fill valve failure

After it has been removed and cleaned, you need to carefully inspect its opening/closing mechanism. Then check the resistance of the element with a multimeter, the optimal value should be approximately 3 kOhm.

A fairly common cause of valve failure is power surges. It is for this reason that manufacturers and service specialists strongly recommend connecting the SMA exclusively through a voltage stabilizer.

Control module

It is necessary to begin diagnosing and repairing it only after all of the above reasons have been “experimentally” excluded. Only after this can you check the “electronic brain” of the washing machine.

At first glance, there is nothing complicated. It is enough to remove the module itself, carefully inspect it, identify defects and burnt-out elements, and then carefully “ring” each circuit. But, as practice shows, it is more advisable to entrust this part of the work to a professional master.
