Ariston Hotpoint dishwasher errors and codes

The developers of Ariston Hotpoint dishwashers thought through not only the design, but also provided the ability to quickly identify malfunctions in the operation of the equipment. The cars themselves signal that a breakdown is brewing. The code displayed on the panel gives the owner the right to decide whether the service center will handle the repairs or he himself will do the repairs. Convenient, right?

You will learn how errors in an Ariston Hotpoint dishwasher are determined from our article. It describes in detail what the program laid down by the engineers warns about. It is described in detail what you can do on your own to correct the situation, and when it is better to contact repairmen.

The article we presented describes the subtleties of diagnostics and gives advice, if followed, the risk of breakdown and failure of the machine is sharply reduced. Photos, video recommendations and reviews are provided as a useful informative addition.

Problems with water intake or drainage

PMM Ariston has a self-diagnosis system. As soon as the control module detects a malfunction, it immediately stops executing the program and displays a hint code.

Let's look at the most common mistakes - from easily fixable ones to those requiring specialist intervention.

AL01 – leak in the car

This code indicates a loss of tightness in the PMM connections. If you look inside the dishwasher, you will probably find water on the tray and a floating “float”, which gave the control board a signal about a problem under the code 01.

On devices without a digital screen, the lights will blink: for machines with 4 programs, the first diode will blink, for a model with 6 modes, the third from the left will blink.

Ariston Hotpoint dishwashers have an AquaStop protection system that blocks the water supply, but sometimes it works not only in an emergency, but also when using highly foaming detergents

What should be done:

Disconnect the device from the power supply. If water is already on the floor, you need to act carefully so as not to step into a puddle.
If the protection is triggered when the tank is full, press the drain program and wait until the chamber is empty.
Shut off the water supply valve to the PMM.
Inspect the rubber band on the device door, check the hose connections, the condition of the clamps and all accessible components. If you find a leak, try fixing the parts or updating the seals. It is better to replace failed consumables, hoses and rubber bands.
During long-term operation, the cause of depressurization may be corrosion of the working chambers. Although Ariston Hotpoint models use high-strength steel, leaks are possible. In this case, worn areas are treated with special sealants and soldering.

If you were unable to find the culprit on your own, you will have to call a technician with a repair kit, who will carry out diagnostics and help determine the reason for the car stopping.

AL02 – no water flows into the machine

Machines with 4 modes without a display will be signaled by flashing the second diode from the left, and those designed for 6 - by the fourth. The first thing you need to do in case of error 02 is to make sure that there is water in the system, but for some reason is not entering the device.

To do this, you can simply open the tap at the nearest water intake point. It wouldn’t hurt to check the shut-off valve if it is installed separately for the PMM.

The inlet filter is installed inside the inlet hose, and its small cells often suffer from rust particles from the water supply, fine sand and other foreign matter

Causes of error 02 and their elimination:

The system has low pressure, i.e. Water flows from the tap under low pressure. The machine does not have enough power, and it will not work. In this case, you should simply postpone washing the dishes until normal flow returns.
The door latch is broken, so the device does not start executing the program, so as not to cause a flood.
The inlet filter or inlet hose is clogged with various impurities found in tap water. In this case, you need to unscrew the fill hose, make sure that it is not pinched and is in good condition. Then rinse it and the protective mesh under good pressure.
Problem with the supply valve. If a blockage is not detected, and water still does not flow into the machine, most likely, the water supply valve has stopped receiving the voltage required from its opening/closing. In 99% of cases, the cause of such a breakdown is power surges. In this case, it is better to replace the part with a new one and connect the device through a stabilizer.

If the machine is under warranty, it is better to contact a service center to replace failed elements.

If the device not only periodically displays an error, but also does not wash and rinse dishes well, most likely the problem lies in the upper or lower spray arm

For long-term machines, one of the frequent breakdowns under code 01 may indicate wear of fasteners in the internal spray system. This kind of damage is easy to fix yourself.

To check the system status, you need to:

Remove the lower basket of the dishwasher - the lower spray arm is installed underneath it. Its blades need to be unscrewed and removed.
Now inspect the fastener - it is essentially a plastic or metal ring that may have cracks or other damage. If problems are found, it is better to replace the mount (and the sprinkler itself) by unscrewing the old fastener using a wrench, and then install a new holder.
The top spray arm is attached to the top basket. To get to it, you need to pull out the tray, release the stops and unscrew the rotating blades.
Here you need to check the rubber sealing ring, the fastening nut and the water supply channel, if necessary, replace the broken elements and reassemble the system.

The reasons for failure of parts are most often scale, penetration of small objects, or natural wear and tear during active use. But such repairs are quite easy to do with your own hands, the main thing is to select an exact match of the parts for your PMM model.

AL03 and AL05 - problems with the drain or pump

Often the reason the machine stops is due to blockages from food residues on the dishes. If the drain hose, pump or pipe is clogged and the maximum time allowed for draining water has been exceeded.

The machine will signal with the numbers 03 . In machines without a display, this will be the simultaneous blinking of 1 and 2 or 3 and 4 diodes (for 4 and 6 programs, respectively).

Checking the drain starts with the filter, which is located at the bottom of the dishwasher - it must be carefully removed, disassembled and washed

In this case, you first need to make sure that the hose is passable - it may simply be pinched or clogged with a “plug” of food waste, as a result of which the pump cannot push waste water into the sewer.

If checking the filter and hose did not help solve the drain problem, the reason may lie in a faulty drain pump. The condition of its connections and wiring is checked with a multimeter. If the voltage indicator is insufficient, the part requires replacement.

If the pump or water level sensor fails, the dishwasher will signal with code 05 or the diodes 1 and 3 or 3 and 5 will flash simultaneously

Drainage problems may also be caused by:

There is a break in the wiring leading to the pump - you need to “ring” and, if necessary, solder the contacts.
Penetration of a small object into the pump impeller - the part is disassembled and the interference is eliminated by mechanical cleaning.
If the water level sensor is broken or its tube is clogged, you need to check the voltage and, if necessary, clean the part.
Problems with the operation of the pump triac on the control module - the element must be replaced with a new one.
Incorrect drain hose connection. A14 is provided for this error , which is displayed if the waste water, instead of going into the sewer, returns back to the machine.

The most difficult case is a board malfunction. But sometimes the problem can be solved with the help of a simple “resuscitation” of the electronics - turn off the power to the device, give 10-20 minutes to rest and reboot.

But even if this method worked, the failure can happen again at any time, so you should contact repairmen from the service center to inspect and reflash the board - perhaps the contacts have come loose or the module tracks need to be re-soldered.

An article fully devoted to this issue will familiarize you with typical actions in the event of a dishwasher of any brand refusing to drain dirty water.

Possible problems with Ariston dishwashers and current methods for correcting them

Let's see what the machine can tell us in different situations. And we will immediately decide what needs to be done. We will designate the signals as follows: code “_”; “_” – number of indicator blinks for a machine with 4 programs; “_” – number of flashes for machines with 6 programs.

Leakage protection has tripped (code AL01; 1 flash; 3 flashes)

It’s worth noting right away that calling this protection the term Aquastop is incorrect. Even if the dishwasher manufacturer himself does this. And for us, copyright is not an empty phrase. The term AquaStop is an entire protection system that includes solenoid valves and sensors.

The name and the system itself are patented and are usually used in washing machines and dishwashers of the Bosch and Siemens brands. We are watching Ariston. In this situation, the leakage protection of the housing, which is a pan with a float, was activated. When a leak occurs, water collects in the pan and the pop-up float blocks its further movement.

We turn off the water supply and disconnect from the network. What is needed to correct the situation? Carefully check all connections through which water circulates and the tightness of the washing chamber. The tube on the circulation pump may have come loose. The pump can be accessed through the bottom of the machine.

Water does not enter the machine (code AL02; 2 flashes; 4 flashes)

According to the manufacturer, you need to immediately check the water inlet valve. There is no reason not to trust a serious company. It’s just better to start with more prosaic things. First, it’s worth clarifying - is there water in the tap? Is its pressure enough? Any dishwasher has a minimum water pressure level at which it can operate normally.

Otherwise, flooding is impossible. Is there water and pressure normal? Then we check the inlet hose along its entire length. There should be no pinches or bends. If there are, they need to be eliminated. If your inlet hose is equipped with a leakage protection valve, check the indicator of this valve.

Sometimes the indicator is the hose itself (it changes color). If the protection is triggered, the valve blocks the water supply directly near the tap. This type of hose has disposable protection and will have to be replaced with another.

It would be a good idea to check the filter mesh at the entrance to the machine. The mesh may well be clogged with rust or other impurities contained in tap water. If this is not the case, then yes, you need to check the water inlet valve. His nutrition may be disrupted. Checking the wires. If necessary, we replace it with a working one.

Ariston dishwasher does not drain water (code AL03; 1-2 flashes; 3-4 flashes)

Failure to drain is almost always due to a problem with the drain pump or water level sensor. The pump may not work (or not work correctly) in several cases:

clogged drain filters,
the pump impeller is blocked,
the pump is faulty (or the wire could simply come loose).

In the first case, if the machine does not drain the water, you need to remove the filters that are located at the bottom of the washing chamber and thoroughly clean them of dirt.

The filters are washed under running water. The sump pump impeller may also be contaminated with food debris or broken dishes. It is necessary to clean it and ensure its unhindered movement. The impeller should rotate without interference.

To check the functionality of the drain pump, you will have to disassemble the lower part of the dishwasher. After removing the base, access to the internal components of the machine opens. When gaining access to the pump, carefully inspect its contacts. Then you need to check the integrity of the windings with a multimeter.

If the pump malfunctions, you will have to replace it with a new one. And the last possible option is a malfunction of the electronic control module. There is no point in trying to repair it. It can only be replaced.

The circulation pump or level sensor is faulty (AL05; 1-3 flashes; 3-5 flashes)

The circulation pump is the main component of the dishwasher, its motor.

To get to it, you will have to disassemble the dishwasher from below (just like when replacing the drain pump). It is necessary to check all the contacts connected to it. If there are breaks, you need to restore the connections. Check the windings.

Disassembling the pump is problematic. Although there are craftsmen who can do this. May need replacement. The level sensor is located in the same part of the machine.

It may also have loose wires or a clogged tube. Most often you will need to replace it with a new one.

The heating element's power supply is broken (code AL10; 2-4 blinks; 4-6 blinks)

A malfunction of the heating element can cause either a lack of heating of the water or its excessive heating. You can get to the heating element using the same method as for checking the drain pump and pump. It is necessary to check the integrity of the contacts.

Again you will need a multimeter. It is necessary to ring the circuit of the heating element. A faulty heating element must be replaced. Sometimes it may be necessary to check the thermistor installed in the heating element. If necessary, we simply replace it with a working one.

Of course, no machine can diagnose problems absolutely accurately, but it will help to indicate the most likely direction of search. For example, if you saw a message on your car about a malfunction of the heating element, and the service technician claims that you need to replace the motor, drain pump and pressure switch, you can politely tell him: Sorry, but you are wrong!

Or something else. A separate description of how to disassemble a dishwasher for further repairs is not at all difficult to find. And who will do this repair - decide for yourself.

Heater malfunction

If you notice that the machine washes dishes with cold water, the problem most often lies in a malfunction of the heating system. It is easy to detect a malfunction: the body of the device remains cold throughout the entire cycle, and traces of fat, food and coloring drinks remain on the dishes themselves, which are usually easily removed with warm water.

If there is a problem in the power supply circuit of the heating element, the dishwasher can heat the water, but this process can take 30-40 minutes, increasing the operating time of the machine

Possible errors and their interpretation:

AL04 – malfunction in the power supply circuit of the NTC temperature sensor. For machines without a display, this will be the signal from diode No. 3 or No. 5 (for 4 and 6 programs, respectively). In this case, it is necessary to disassemble the machine, inspect and check the voltage at the sensor contacts.
AL08 – heating sensor malfunction (4 diodes blinking). If the PMM signals a sensor malfunction, this does not mean that it has failed. Perhaps the part is poorly secured to the tank or there is a break in the wiring in the circuit from the module to the sensor.
AL10 – problems with the heating element (simultaneous flashing of 2 and 4 or 4 and 6 diodes). The cause of the problem may be a break in the chain of wires leading to the heating element, a burnt-out relay on the control module, or combustion of the heating element itself. Such failures are common in areas with hard water. In this case, you need to disassemble the machine, check the wiring, and possibly replace the heater or module.

Since restoring the heating system requires dismantling, disassembling the device and professional diagnostics, you should not attempt it yourself without decent experience working with electronics. In this case, the most correct decision would be to contact the Ariston service center.

For Ariston Hotpoint models that are not equipped with a digital display, you can use this decoding table to independently diagnose the most common breakdowns (+)

But sometimes problems with the heating system can be the result of improper operation. For example, if the machine is not connected correctly, it will constantly draw and drain water without having time to heat it up.

Alas, such cases are not uncommon if you entrust the installation of a PMM to an inexperienced technician. The solution here is obvious - dismantle and reconnect the device.

There are malfunctions in the operation of equipment that the owner himself can correct without any problems. Methods for doing your own dishwasher repair are described in our recommended article. In addition, the technical documentation for the equipment always contains a description of the simplest defects and actions to eliminate them.

Another easily fixable problem is a clogged filter, as a result of which water circulation deteriorates and the heater simply does not turn on. Therefore, before contacting the service center, try to clean the filters, hoses and check this guess.

Ariston Hotpoint dishwasher errors: error codes and how to resolve them

Errors of key elements of the device

Clearing blockages and replacing worn gaskets is a task that does not require special qualifications or special tools. But when the electronics or the main components of the device fail, you have to partially disassemble the machine and know how to properly dismantle and check its elements.

Repairing the control board requires serious skills in working with electronics, but replacing it is quite simple - you just have to disassemble the dishwasher door, remove the control panel and disconnect the sensors with wires

Serious malfunctions in the operation of the dishwasher, requiring a mandatory call to a technician from a certified service department, include error 06 - a violation in the power supply circuit of the fill valve.

The video will introduce you to the features of identifying and eliminating breakdowns:

Complex breakdowns in which it is better to call a specialist:

AL07, AL08, AL09 – errors in the operation of the control module.
AL10 – problems with the heating element or electrics of the intake valve.
AL11 – failure of the circulation pump that supplies heated water to the sprinkler system. If this part breaks, the machine will draw water, heat it, but at the washing stage it will turn off.
AL99 - means that there is a break in the internal wiring or damage to the network cable. Requires checking all wires or replacing the control module.

If such errors appear, you should first clean the filters and reboot the system. If you know how to use a multimeter, check the resistance of the thermistor, heating element, circulation pump and inlet valve.

But the problem with such failures is that any technician, even offhand, can name a dozen possible breakdowns for each of these errors. Therefore, it is still better to carry out a complete diagnosis of the device.

The author of the video talks in detail about the causes and methods of eliminating breakdowns indicated by code numbers 10 and 11:

Dishwasher self-diagnosis

Various machines of this brand have the ability to diagnose various types of faults and inform the user about them using the control panel. Information can be displayed in various ways:

on the display screen in the form of a special code;
on the LED indicator of machines with 4 programs;
on the LED indicator of machines with 6 programs.

In the case of cars without a display, information is provided by a certain number of indicator flashes. For machines with 4 and 6 programs, the fault symbols are different. Therefore, we will consider them as different. The only clarification is that the indication may indicate several possible malfunctions.

Ways to prevent dishwasher breakdowns

Although the Ariston Hotpoint is a very reliable dishwasher, operating errors can damage it too. The technician will “report” on all types of possible malfunctions in a timely manner; you just need to understand the nuances of deciphering the codes in order to determine the necessary and sufficient measures to eliminate the cause of the malfunction.

And in order not to become a regular customer of repair shops, you just need to follow the operating rules and follow a few tips that will extend the life of the equipment.

In some models, if used incorrectly, code 13 is displayed, which means that the valve in the detergent compartment cannot open due to powder residue or the dishes are not stacked correctly.

Recommendations for use:

Ariston Hotpoint has filters that purify water from various impurities. To avoid clogging, they must be cleaned in a timely manner.
It is recommended to install a grease filter at the entrance to the sewer to avoid external blockages.
To make the machine easier to operate, wipe the dishes with a napkin before loading to remove any remaining food.
If your water supply has hard water, use regenerating salt softeners or install a special filter at the inlet to the PMM.
Do not use soap, shampoos or other substances not intended for dishwashing equipment as cleaning ingredients. Only specialized detergents with characteristic low foaming are suitable for operating the dishwasher.
Do not overload the dishwasher with items. You should strictly follow the manufacturer's recommendations for loading the dishwasher given in the data sheet.
After each start of the machine, wash and dry the tablet tray.
Place dishes so that they do not touch or block the spray arms.

And the last piece of advice - at least once a month, arrange a “clean day” for your assistant, running it in idle mode along with a cleanser and disinfectant.

What can happen to an Ariston dishwasher

Before you try to figure out the problem yourself or grab the phone to call a service technician, it would be better to decide what exactly doesn’t work in the dishwasher?

It's no secret that service centers have big appetites. Anyone who has already encountered an unobtrusive service knows that they will often tell you how much needs to be “repaired” and how much all this “pleasure” will cost you.

To avoid being deceived, determine the type of breakdown yourself. There will be no difficulties with this. And the Ariston dishwasher itself will help with this. Its manufacturer took care of this in advance.

Conclusions on the topic

If you are well versed in repairing household appliances and are planning to troubleshoot your dishwasher yourself, then you should try it. True, there is a sure way to avoid such troubles - compliance with operating rules.

The Ariston Hotpoint dishwasher is a faithful assistant that, with proper care and proper operation, will serve without problems or breakdowns for many years. However, if you still encounter a problem with the electronics or control module, it is better to immediately contact a qualified technician without wasting time on independent experiments with equipment repair.

Would you like to tell us how your dishwasher code system helped you identify the cause of a malfunction in a timely manner? Do you have information that is worth sharing with site visitors? Please write comments in the block below, post photos related to the topic of the article, and ask questions.

Meaning of Hotpoint-Ariston codes

Modifications of this family are also programmed for notifications of different types: text and LED flashing.

Codes	PMM lamps with four modes	PMM lamps with six modes	Cause	Elimination
AL-01	№1	№3	The “Aquastop” function worked.	Repairing a leak
AL-02	№2	№4	No water intake.	Checking the fill valve
AL-03	№1,2	№3,4	There is no drain.	Verification required:

As you can see, in most cases complex repairs are not required. Problems can be easily fixed with your own hands after rebooting the equipment.

How to reset a dishwasher?

Before troubleshooting, you need to reset the code by unplugging the machine. To do this, press the mode selection key and hold it for about 15-20 seconds - now you can remove the plug from the socket. Do not look into the machine immediately after turning it off, as this can cause burns to your face and hands. Wait a few seconds for the steam to release.

Ariston Hotpoint dishwasher errors and codes, Ariston dishwasher error code.

Preparation for subsequent disassembly

The principle of assembly and disassembly for built-in and free-standing dishwashers is the same. The only difference is that the built-in ones do not have a removable top cover and metal walls. By the way, free-standing models of dishwashers can be considered partially built-in. With the top cover removed, they fit perfectly under the tabletop, but at the same time they retain their own (and not furniture) façade.

Before starting to disassemble the dishwasher, be sure to disconnect it from the power supply. Then we turn off the water supply. Now you can work without expecting surprises.

A small addition - machines from different manufacturers may have different configurations of fasteners. For example, at Bosch and Siemens all fastening screws are made in the form of an asterisk of a certain size.

It is necessary to prepare the appropriate tool in advance. Screwdrivers, pliers and a set of keys will also come in handy.

We remove everything that may interfere with disassembly. Disconnect the water fill and drain hoses. Open the door and take out the removable baskets for dishes and attachments. It’s clear that there shouldn’t be any dishes there. If you find any remaining water, remove it with a rag or sponge. During disassembly, water will still come out. Therefore, there is no need to remove funds to collect it far.

Now you need to move the machine to a place where there is enough space to disassemble and place the parts to be removed. Try to prepare boxes or bags for storing small parts and screws.

Otherwise, subsequent assembly may be delayed. It is advisable to have a camera or phone with a camera nearby. During the process of disassembling and disconnecting tubes or wires, it is better to capture how everything happened. Then the reverse assembly process will not be surprising.

Fault signals for popular models

If water does not flow into the machine at all, the essence of the problem is clear. But sometimes the appliance simply does not receive enough water to fully wash or rinse: we see that the drum is not empty and cannot determine the cause of the problem.

In this case, the signals from the machine itself will help, which are displayed on the display immediately or after starting the diagnostics.

In many washing machines, if the supply is insufficient or the water intake system is broken, the chemical formula of water is displayed on the display - H2O

Problem codes with water intake for some popular models:

Asko – Water inlet fault or E01;
Zanussi and Electrolux – E10 or E11;
Candy – E02;
Ariston, Hotpoint Ariston and Indesit – H2O;
Samsung – E1;
LG – PE or IE;
Whirlpool – F01 or FH;
Bosh - F01 or Aquastop.

If the washing machine is not equipped with a display, the causes of the malfunction will be indicated by flashing lights on the panel. This code is programmed at the factory, so its meaning depends on the specific model, and a decoding table is included in the product instructions.
