How to reset an error on a hansa dishwasher

If a malfunction occurs, an error code appears on the dishwasher display. With its help, it is possible to determine the condition of the equipment, the type and severity of the breakdown. Below are the error codes for Hansa dishwashers.

What's wrong?

The control signal about the locking of the machine door has stopped or there is no locking at all.

The reason may be that the door is not completely closed. In this case, you should pay attention to the condition of the wires connecting the controller and the door lock. There may also be a malfunction in the lock itself or the limit switch. Finally, you should look at the condition of the CM wiring.

The time for filling the tank with water to the required level has been exceeded. The excess was 2 minutes.

The problem lies in low water pressure. An error can also occur as a result of clogged hoses through which water enters the machine, or failure of:

In more expensive models, it is worth paying attention to the operation of the Aqua Spray ASJ system.

In an hour, the water in the dishwasher did not heat up to the temperature set in the program.

The error occurs when one of the parts that are responsible for heating the water breaks down. Such details include:

Sensor. In this case, we are talking about a temperature sensor or thermistor, which requires diagnostics and replacement when an error occurs.
Level sensor. If the device breaks down, excessive amounts of water may enter the chamber.
Thermistor. The device is not working properly and needs to be replaced.
Heating element control circuit. There may be a rupture in it. It is not necessary to change the chain; sometimes it is enough to ring the part and tighten the contacts.
Heater. If it burns out, then it can only be replaced.
Controller. It also requires replacement if it fails.

Also, the cause of the error may be a short circuit in the heating element circuit, due to which liquid begins to flow onto the housing.

Water pressure too strong. An error also occurs if there is overflow of liquid.

In case of high pressure, it is more difficult for the valve to cope with the incoming fluid flow. The result is a large amount of water entering the chamber. Possible ways to solve the problem.

Call a plumber. The specialist will conduct diagnostics and reduce the pressure in the system.
Close the water supply valve to the dishwasher. You can do this yourself.
Replace the faulty fill valve.
Check the condition of the wiring and repair it if necessary.
Change the level sensor.

Also, the cause of the error may be failures in the electrical network. In this case, it is enough to reset the device settings.

The water does not heat up.

The reason is a failed temperature sensor. This device begins to send incorrect information to the dishwasher, causing the liquid to stop heating to the required level.

You can solve the problem in the following ways.

Check the condition of the wiring connecting the sensor or heating element. Through diagnostics, it will be possible to assess the reliability of fastening contacts and connectors. If a breakdown is detected, it can be quickly fixed. You should read the instructions first.
Replace a sensor that may have failed.
Carry out professional diagnostics in the event of a breakdown of the control controller.

The last option requires inviting a specialist.

If a similar error occurs on the control panel, you should follow the same steps as listed for error E6.

Water stops flowing into the car.

The problem occurs due to a faulty distribution valve that blocks the flow of fluid. In this case, there is only one way out - to replace the broken device.

If the problem is not with the valve, it is worth checking the drain hose for kinks. Finally, the problem may arise from a shorted triac. A reason like this will require the presence of a professional.

An error occurs when switching the sensor.

Typically, the problem may be due to dirt on the touch control panel or the buttons on it. An error occurs if the switch is pressed for more than 30 seconds. The solution is quite simple: clean your dashboard.

Also, during operation of the Hansa dishwasher, the “Start/Pause” indicator may begin to flash. The problem lies in the door of the device not being fully closed. If the indicator blinks even after closing the door again, you should contact a technician.

When is specialist help needed?

During the operation of Hansa dishwashing equipment, various difficulties and problems arise due to wear and tear of elements, devices, and consumables. Most errors that occur on the dashboard due to the operation of sensors can be eliminated independently. But there are times when specialist help is required.

You will need to call a specialist if:

error codes continue to appear on the screen even after self-repair of devices;
the dishwasher begins to make strange sounds and vibrate;
obvious deterioration in the performance of the device becomes noticeable.

It is not recommended to ignore any of the listed options. Otherwise, there is a risk of rapid failure of structural elements and devices, which will lead to the cessation of operation of the equipment and the need to purchase a new unit.

A specialist will conduct a thorough diagnosis and help solve the problem in a short time.

In this case, the technician will not only restore the dishwasher to working order, but will also help you save money by solving the problem in a timely manner.

Prevention measures

You can extend the life of your dishwasher. A number of tips will help with this:

Before placing the dishes in the sink, they must be thoroughly cleaned of food residues;
Before starting the machine, it is worth checking that the equipment is connected correctly;
In the case of using expensive models, it is recommended to install a circuit breaker.

Using the latter, you can prevent damage to the device during a network reboot. Finally, experts advise using high-quality detergents that will not harm the structure of the equipment.

Hansa dishwashers are characterized by a long service life and high performance. Studying error codes will prevent premature failure of the device and help extend the life of the equipment.

To understand the reasons for the breakdown, knowledge about the principle of operation of the dishwasher will be useful. Let us briefly and clearly describe the sequence of stages:

Loading dishes, turning on the program.
Switching on the solenoid valve, water intake.
Pumping water with a circulation pump through a heating element, heating it.
Hot liquid is fed into the spray nozzles and flies out of the nozzles under pressure.
The waste liquid goes into the drain filter, where it is cleaned and can be reused.
After rinsing is completed, the water goes down the drain.
Drying starts or the cycle ends.

Why does the car fail? There are several main reasons:

Poor build quality. Manufacturing defects.
Unstable voltage in the network, which leads to damage to electronics.
Incorrect installation and connection of the PMM.
Using low-quality detergents.
Operational problems.

A common problem is blockages in the drain and fill paths. Hence the problems with collecting or draining water. Poor cleaning of dishes before loading leads to foreign objects entering the filter and pump.

What problems are typical for Hansa dishwashers? In first place, according to the service centers, was a malfunction of the pressure switch, or more precisely, its electrical part. Users also complain about the following:

The machine does not turn on;
Very bad at washing dishes;
The body is electrocuted;
Noise during operation;
Poor supply of detergent.

In addition, error codes on the display can indicate a breakdown.

How can I fix these problems? Let's figure out in what cases you can carry out repairs yourself, and when it is better to call a specialist.

How can I fix these problems? Let's figure out in what cases you can carry out repairs yourself, and when it is better to call a specialist.

Troubleshooting methods

Change in line pressure

The manufacturer has designed it in such a way that the flow sensor in the Hansa dishwasher is set to a specific pressure range of 2.5 to 6 atmospheres, which is most often provided in the mains of residential complexes. Error code e1 is diagnosed when there is a deviation both upward and downward.

When there are surges in water pressure, if you are not going to just wait for everything to stabilize by itself, experts recommend installing an adjustable pressure relief valve that compensates for the change in pressure and your dishwasher will work with the parameters set by the manufacturer.

Problems with filter and inlet valve

These two parts are next to each other, so it makes sense to clean and check them as a pair. Before doing this, do not forget to turn off the power to the machine and turn off the water supply. First of all, it is necessary to dismantle the intake mechanism along with the hose. To do this, you need to unscrew one end of the intake hose from the body and the other from the water line fitting.

The filter is located near the intake site and has the appearance of a thin fine-mesh mesh. We thoroughly clean the mesh and hose from any deposits that may have been caused by water. If the filter is damaged, it is better to replace it, as it prevents clogging of internal elements, which are much more expensive and vulnerable to contamination.

The valve itself is checked for electrical circuit integrity using a conventional tester. If the test gives a positive result, then we assemble the assembly in the reverse order - first we insert the flow element, then we connect the assembly to the hose and connect the body and the water main tee. It's worse if the valve fails.

How to fix a broken valve? Most breakdowns cannot be repaired at home. If the intake device malfunctions, you need to purchase a new one from the store and install it yourself, which is not difficult.

Checking the drain

The next step is to check the functioning of the drain in the Hansa dishwasher. Violation of the normal draining mode will result in error e1 constantly appearing on the screen and the dishwasher will be unusable. To do this you need to do the following:

unlock the hopper lid;
pull out the lower basket;
unscrew the drain element and clean it from the applied dirt;
Unscrew the screws holding the seat;
pull out the flap;
check the possibility of free rotation of the impeller and the presence of debris in the rotation zone, clean the blades from possible plaque and dirt.

If after all these manipulations the machine does not display error e1, then the reason was the poor functioning of the drain system.

Checking the flow sensor

Another option that can be identified as the cause of error e1 is a malfunction of the flow sensor. On the Hansa dishwasher it is located behind the side wall on the left edge.

After dismantling the wall, remove any remaining water from the tank. Dirt, as well as small particles of impurities from the water, regularly get into the hollow tubes and are retained, which causes the controller to operate incorrectly.

If this does not help, then most likely the sensor is faulty and needs to be replaced. Electronic spare parts of this kind cannot be repaired due to their design. Just don’t forget to take a photo of the connection diagram, otherwise you will spend more time installing the new element than necessary.

If, after all your attempts, error e1 continues to appear in your Hansa dishwasher, then it would be a wise decision to consult a specialist who will tell you what to do.

Modern household appliances are designed in such a way that minor repairs or replacement of consumables can be performed by almost anyone. As a rule, such cases are described in detail in the operating instructions. Complex repairs are carried out in specially equipped workshops and are done by professionals with extensive experience.

What to do when an error code appears

When an error code appears, you need to refer to the instructions for the dishwasher to find its explanation and understand what the reason is and what exactly is wrong with the unit.

Contact VseRemont24 if:

The instruction manual for your dishwasher “helper” is lost somewhere.
You haven't fully understood the description of the error.
You took independent actions to eliminate the problem, but they did not produce results.
We realized that the dishwasher needs repairs, and you need the help of a professional and experienced technician.

Dishwasher malfunctions can be minor and can be fixed within a couple of minutes, but most of them require complex repairs.

Any external or internal part, as well as the entire unit of the dishwasher, can fail.

Failures of important components lead to the most common malfunctions:

water leak,
lack of dialing, draining water,
no heating/overheating of water,
insufficient amount of water,
inconsistency of electrical network parameters with the necessary ones,
program malfunctions,
failure to perform individual functions or complete failure of the unit to work, and so on.

A faulty dishwasher works worse and does not wash dishes well. From a technology that saves water and electricity, it turns into an expensive “pleasure”. What is most important is that using a faulty electrical appliance is unsafe for people’s health and lives!

How to avoid damage to the PMM

Following the instructions will allow your equipment to last longer. Follow simple rules:

Clean dishes well to remove any leftover food.
Install equipment correctly. Often the reason for the lack of water is an incorrect connection.
Install a circuit breaker for expensive devices. This applies to Hansa dishwashers and washing machines. The machine turns off the power when there is an overload in the network.
Use a quality detergent.
Check that the door is closed tightly.
Load dishes according to the instructions.

It is easier to prevent a breakdown than to repair it. Take care of your equipment, and it will take care of your dishes.

Description of error messages

The information provided on the display may vary for different Hansa models. Therefore, the following are the codes that are used on most models.

Error code E01 indicates that the tank is filling with water too slowly. There are many possible reasons for this. Some of them are easy to fix yourself without contacting the service.

This message may appear due to the following reasons:

It is possible that water is not entering the machine at all. This is possible if the hose is clogged or pinched. Then it is enough to conduct an inspection and correct the situation.
Sometimes the electronic control of your Hansa dishwasher can obstruct the flow of water. This happens if the door is not tightly closed. It's enough to just close it tighter.
When water enters the machine, it passes through the solenoid valve. If the latter becomes faulty, replacement is required.
The filling level of the chamber is determined using a special sensor. If it gives incorrect data, this may cause water not to flow.
Sometimes it may happen that components and mechanisms are working correctly, but problems have occurred with the wiring. In this case, you need to check its serviceability and make sure there are no burnt wires. If an error is detected, the connection must be restored.
If irregularities are detected in the operation of the control electronic controller of the Hansa machine, then to correct the situation you will need to contact the service to repair or replace it.

In most situations, repairs can be carried out independently.

When code E3 appears on the display, the error relates to the heating system. This manifests itself in the fact that after 60 minutes have passed, the water in the Hansa dishwasher is still not heated to the level required for washing.

In this case, the source of breakdowns may be the following:

It is possible that the temperature sensor is broken. If this is the case, then replacement is required.
The level sensor is faulty and a new one will need to be installed.
It happens that the chamber now has too much volume. This is a sufficient reason for the heating to be insufficient. This happens, for example, if it was not detected in time that there was already enough water in the tank.
If the wiring in the circuit that supplies energy to the heating element is broken. Then you need not only to check whether the contacts have come loose, but also to ring this entire circuit to detect a breakdown.
Sometimes the heating element shorts to the body. In this case, it is better to replace this unit.
If the heater burns out, then only replacing it can help.
The operation of the dishwasher is controlled by an electronic board. If there are problems with it, then it must be addressed to a specialist workshop. In this case, it is impossible to carry out repairs on your own.

It happens that the amount of water that pours into the tank is too strong. In this case, the electronic diagnostics should issue code E4. Sometimes the result of intensive water flow is overflow.

To eliminate the breakdown, you need to take into account that the reasons may be the following:

It is possible that the water entering through the plumbing system is under too much pressure. If the water supply is faulty, it is recommended to invite a plumber to repair it. However, there is also a situation when it is enough to simply reduce the water pressure in the hose.
A faulty fill valve cannot be repaired; it must be replaced.
If the pressure switch is working properly, but there is a break in its circuit, then to repair it you need to ring the contacts and correct the found break.
Sometimes the level sensor does not detect a situation when the tank is full of water due to a malfunction. Water continues to flow and overflow occurs. Replacing the level sensor will help here.
If the control board does not work properly, it becomes necessary to repair the electronic device. Only a service professional can do this.

For the device to operate, it is important that the machine receives reliable data from its nodes. If the temperature sensor is faulty, code E6 will appear on the display. In order to take action, you need to check the following:

It may turn out that the sensor itself is working, but the wiring that goes to it is damaged. In this case, you need to inspect it for damage and call if necessary. Then you need to restore the connections.
If the sensor is broken, then there is no point in repairing it - the situation can only be corrected by replacing it with a working unit.
The operation of the Hansa dishwasher is organized by an electronic control board. If there is a malfunction in it, then there will be a complex repair that is almost impossible to carry out on your own. To do this, you need to contact a specialist in a repair shop.

If error E7 is displayed, this indicates a malfunction of the temperature sensor. It is necessary to react in this situation in the same way as to error E6.

In a situation where the machine has identified the failure code as E8, the faulty unit is clearly identified - this is the inlet valve due to which water does not flow. In this case, do the following for repair:

If the valve is broken, you need to replace it with a new unit.
The drain hose may be connected incorrectly.
A triac short circuit occurred on the control board. Now you need to call a specialist who will check and repair or replace the control board.

If there is no code on the display, but the indicator (Start/Pause) is flashing, this indicates that the door is not tightly closed.

Error codes and their elimination

What's wrong?

The control signal about the locking of the machine door has stopped or there is no locking at all.

The time for filling the tank with water to the required level has been exceeded. The excess was 2 minutes.

The problem lies in low water pressure. An error can also occur as a result of clogged hoses through which water enters the machine, or failure of:

Also, during operation of the Hansa dishwasher, the “Start/Pause” indicator may begin to flash. The problem lies in the door of the device not being fully closed. If the indicator blinks even after closing the door again, you should contact a technician.

Two ways to reset dishwasher errors

If you have figured out the cause of the breakdown and decided on further actions, you can reset the error code.

There are two easy ways to do this:

Disconnect the dishwasher from the power supply for 15-20 minutes. This time is enough for the control module to reset its settings and restart.
Power on for 10-15 seconds . After this action, the equipment settings are also reset.

The recommendations described are suitable for dishwashers of different brands and models.

How to reset all Bosch dishwasher errors

One of the most popular in our country, the German manufacturer of household appliances Bosch, has provided for immediately resetting all previously accumulated errors in its units.

Adding a solution

It is forbidden to write answers that do not bring any benefit to the questioner from the series: “take it to the service center”, “contact the ASC”, “unprofitable”, etc. Such answers will be considered a rating increase, the answers will be deleted, and the account will be blocked.

If you undertake to help people, answer fully. Explain why, if you recommend, for example, to reflash the phone, then write how to do it. If you write that repairs are unprofitable, explain why.

Adding answers that essentially repeat existing answers on this issue will also be considered cheating.

Miele and Kaiser dishwasher errors

Next, according to the plan, we will consider system errors in Kaiser dishwashers. These errors also begin with the letter E and also go in numerical order, but the decoding of the codes is different, so it’s easy to get confused here - be careful. E1 – The dishwasher spends too much time collecting water into the reservoir. E2 – the dishwasher cannot drain dirty water for the period of time specified by the program. The remaining decodings (E3, E4, E5, etc.) are the same as for the Krona dishwasher (see the previous paragraph).

Important! On some models of Kaiser dishwashers, errors E1, E2, E3, E4, etc. identical to errors E01, E02, E03, E04, etc.

System error codes for Miele dishwashers differ from those discussed above. Let's look at them.

F01 – the heating element is shorted or the temperature sensor is burned out.
F02 – the heating element fuse has tripped. It is necessary to check the resistance of the heating element and its electrics, detect and eliminate the breakdown, and then replace the fuse ; the article Repair of Miele Dishwashers is written about detailed repairs.
F04 – the temperature sensor (NTC sensor) is broken.
F11 – The Miele dishwasher tries to remove water, but it does not leave, or it leaves extremely slowly.
F12 – tap water either does not fill the tank at all, or it does, but extremely slowly.
F13, F14 – the pressure of the water entering the dishwasher is extremely low and the pressure of the water circulating in the machine is low.
F1E – there is no signal from the water flow sensor, most likely the tap is turned off or there is no water in the water supply.
F3E – interruptions in the operation of the pressure switch or heating element.
F78 – circulation pump jammed due to blockage. In rare cases, the cause of error F78 is a breakdown of the control board.

For your information! The appearance of a system error in Miele dishwashers is accompanied by an unpleasant sound signal, after which the dishwasher stops working.

Hansa dishwasher error codes - how to decipher

Dishwashers of this brand are produced in China. One of the important features of such devices is the economical use of available resources. This car brand began its existence back in 1997. However, already at the beginning of the 2000s, this equipment appeared on the Russian market. Most models can be classified as budget or middle class. If malfunctions occur, the owner sees error codes for Hansa dishwashers, which allow them to determine the type of malfunction and put them into working order.

How to solve error E1

How to fix the E1 dishwasher error can be fully understood after the exact breakdown has been diagnosed and the technician has assessed the scale of the problem. So, if the user assumes that water has not filled into the machine due to a blockage, then it is necessary to act in this situation according to the following principle:

the water supply to the dishwasher is completely shut off;
the hose from the dishwasher body is unscrewed;
the internal contents of the hose are checked;
if dirt accumulates in the hose, the system is washed under intense water pressure;
the filter mesh is additionally inspected; if necessary, this part is also cleaned under running water;
Additionally, the intake valve channel is completely inspected.

General information

Almost all the latest models of devices include a display on which the Hansa machine can display messages for the owner. If an error occurs, the machine automatically determines its source and issues the necessary code. In accordance with the information received, the user determines what happened and knows what is recommended to be done to clarify the received data and for repairs.

However, older models, many of which are still in use, did not have displays installed. However, the designers provided the opportunity to find out exactly what problem arose. Data is transmitted by flashing indicators installed on the panel. In some models, both methods can be used simultaneously.

Description of error messages

The information provided on the display may vary for different Hansa models. Therefore, the following are the codes that are used on most models.

Error code E01 indicates that the tank is filling with water too slowly. There are many possible reasons for this. Some of them are easy to fix yourself without contacting the service.

This message may appear due to the following reasons:

It is possible that water is not entering the machine at all. This is possible if the hose is clogged or pinched. Then it is enough to conduct an inspection and correct the situation.
Sometimes the electronic control of your Hansa dishwasher can obstruct the flow of water. This happens if the door is not tightly closed. It's enough to just close it tighter.

If irregularities are detected in the operation of the control electronic controller of the Hansa machine, then to correct the situation you will need to contact the service to repair or replace it.

In this case, the source of breakdowns may be the following:

It is possible that the temperature sensor is broken. If this is the case, then replacement is required.
The level sensor is faulty and a new one will need to be installed.
It happens that the chamber now has too much volume. This is a sufficient reason for the heating to be insufficient. This happens, for example, if it was not detected in time that there was already enough water in the tank.

If error E7 is displayed, this indicates a malfunction of the temperature sensor. It is necessary to react in this situation in the same way as to error E6.

If the valve is broken, you need to replace it with a new unit.
The drain hose may be connected incorrectly.
A triac short circuit occurred on the control board. Now you need to call a specialist who will check and repair or replace the control board.

Causes of breakdowns of the Hansa dishwasher

Let's look at the main reasons why the Hansa dishwasher malfunctions. To make it easier to understand, pay attention to the “behavior” of the machine.

The PMM does not start the wash. The failure is expressed in the fact that after drawing and heating water, the washing cycle does not begin. The drain filter or the nozzles on the rocker arm that spray water are probably clogged. In this case, the machine washes the dishes very poorly if the cycle starts. What happens less often is the breakdown of the circulation pump that pumps water into the dishwasher.
The equipment does not draw water into the tank. A simple malfunction is a blockage in the system. It's easy to fix yourself. A more complex breakdown is a malfunction of the fill valve; You can't do without repairs.
The dishwasher does not heat the water and the dishes are difficult to wash. This means that there are problems with the heating element, which is responsible for heating the water. Another sign of a breakdown is that the machine is electrocuted. The wiring is checked and the heater is tested with a multimeter. The faulty element is replaced.
The machine collects and drains water or collects more than normal. The problem must be looked for in the pressure switch. The device controls the amount of water in the tank. If it fails, a complete replacement is needed.
The PMM does not drain the water after finishing the wash. Then you need to check the drainage path: filter, pump, drain hose.
Is there a water leak? Then all connections, the tank are inspected, and the seals are checked.

Now you know why the Hansa dishwasher does not work as usual. It happens that the dishwasher does not turn on at all. Then check the voltage in the outlet by connecting another device to it, and inspect the power cord for damage.

If everything is normal, the equipment could have suffered from a power surge. Diagnose the control board fuses before turning on the PMM.
