Error codes for Electrolux dishwashers (Electrolux)

There are 2 types of Electrolux dishwashers: models with and without display. The screens show information important to the user, such as fault codes. On devices without displays, various problems are indicated by light signals that appear on the control panel. By the frequency of flickering you can judge about a particular breakdown. There are also models that warn of problems using light signals and by displaying relevant information on the screen.

Most often, users encounter water heating problems. Problems with heating will be indicated by code i60 (or 6 light flickers on the control panel). In this case, the water can either overheat or remain cold.

If the error appears for the first time (this applies to any code), you should first try to reset it. To do this, you need to disconnect the equipment from the electrical network, wait 20-30 minutes, and then plug it back into the outlet. If a restart did not help to “reanimate” the device, and the error appears again, you will have to look for the cause of the failure.

The i60 code is displayed due to:

malfunction of the heating element or damage to the power cables;
failure of the thermostat, control board;
broken pump.

To fix the problem, you need to check each of these components. First of all, you need to rule out problems with the wiring and heater. If necessary, replace the cable or heating element with a new spare part. If the pump fails, the water will not circulate well. Setting up a control board is a difficult task. If the control module fails, it is recommended to call a specialist to repair the dishwasher.

The code i70 displayed on the display indicates a breakdown of the thermistor (in this case, the light on the control panel will blink 7 times).

The problem most often occurs due to burnout of contacts during a short circuit. The part needs to be replaced with a new one.

Problems with draining and filling water

If any problem occurs, you should first try to reset the error by disconnecting the equipment from the power supply. If such actions do not bring positive results, you need to look for codes and make repairs.

For different problems with draining/filling water, different error codes appear on the display.

i30 (3 light flickering lamps). Indicates that the Aquastop system is activated. It is activated when an excessive amount of liquid stagnates in the pan. This problem is the result of a violation of the tightness of the storage container, cuffs and sealing gaskets, a violation of the integrity of the hoses, and the occurrence of leaks. To eliminate the breakdown, you need to carefully inspect these components and, if necessary, replace them.

iF0. The error indicates that more water has filled into the tank than it should. In most cases, selecting the waste liquid drain mode on the control panel helps resolve the error.

Noise in the dishwasher

If your dishwasher starts to make a lot of noise, you need to determine the source of the noise. If the pump rattles, then there is nothing to worry about - this unit itself is noisy. Too much noise may indicate that something has got into it. Sometimes extraneous sounds are a harbinger of the imminent “death” of the pump. The repair method is to replace the drain pump.

In some cases, loud noises may be caused by the Electrolux dishwasher motor. The bearings are rattling here, damaged by water leaking from under the seals. The repair process consists of replacing bearings, and in the most difficult cases, completely replacing the entire engine (circulation pump).

Don't forget to check the rotating rocker arms and their mechanism - it is quite possible that the source of the noise is somewhere here.

Problems due to blockages

Users of any dishwasher often encounter system clogging. With such a malfunction, the following codes may appear on the display.

i20 (2 light flashes of the lamp). Waste water is not discharged into the sewer system. This code “pops up” due to a blockage in the system, a pump blocked by debris, or squeezing of the drain hose. First of all, you need to check the hoses and filters for blockages. If they are detected, you need to remove the accumulated debris, rinse the hose and filter element. If the problem is not clogged, you need to remove the pump cover and see if any trapped debris is preventing the impeller from working, and if necessary, clean it. If a bend in the hose is detected, it should be positioned straight so that nothing interferes with the outflow of waste water.

i10 (1 light flashing of the lamp). The code indicates that water is not entering the dishwashing tank or is taking too long to fill. Each model is given a strict time limit for such manipulation. Problems with fluid intake from the system arise due to blockages, temporary shutdowns of water due to planned repairs or emergency situations.

Blockages

Since the water in the central system is of low quality, problems with clogs in dishwashers arise quite often. But in most cases, the problem can be solved on your own.

If there is a malfunction, the dishwasher displays the following codes:

1. i10 - water does not enter the tank or is being filled for a long time (signal - 1 flash). A problem arises as a result of a clogged valve, hose or filter in the inlet system, or there is no central water supply.

Depending on the reason for stopping the water supply, the following actions must be taken:

2. i20 - waste water is not drained (signal - 2 flashes). A malfunction may occur as a result of a clogged pump, drain hose or filter, stoppage of the drain pump, squeezing of the drain hose, or malfunction of the level switch.

To resolve the problem, you can do the following:

Sensor malfunctions

Electrolux dishwashers are “stuffed” with electronic sensors that are responsible for the operation of the device. For example, they monitor water temperature, its quality and other parameters.

If there are problems with different sensors, the following codes “pop up” on the display.

ib0 (light notification - flashing of the lamp on the control panel 11 times). The code indicates problems with the transparency sensor. The device often produces such an error if the drain system becomes clogged, a layer of dirt forms on the electronic sensor, or it fails. In such a situation, first of all you need to clean the drain system and the sensor from contamination. If such manipulations do not help, the sensor should be replaced.

id0 (lamp blinks 13 times). The code indicates interruptions in the operation of the tachometer. It controls the rotation speed of the motor rotor. Problems often arise as a result of loosening of fasteners due to vibration, rarely - when the sensor winding burns out. To fix the problem, you should evaluate the reliability of the sensor fastening and, if necessary, tighten it. If this does not help, it is recommended to replace the broken electronic sensor with a new one.

i40 (warning – 9 light signals). The code indicates a problem with the water level sensor. The error may occur due to a failure of the pressure switch or control module. To fix the problem, you need to replace the sensor, repair or reflash the module.

Errors related to sensor operation

Error iB0 or indicator blinking 11 times. This code indicates that the transparency sensor is damaged. Possible reasons:

the sensor is dirty,
the level relay does not function,
The drainage system is clogged.

Solutions:

clean the loading chamber and sensor,
Perform routine maintenance specified in error i20.

If the breakdown persists, the turbidity control sensor must be replaced.

Error iD0 or indicator blinking 13 times. There is a violation in the speed control control system of the circulation pump motor (problems with the tachogenrator). The water does not heat up. Possible reasons:

a break in the electrical circuit of the sensor or loose contact connections,
The capacitor in the engine starting circuit has burned out,
due to loosening of the sensor, vibration appeared,
damage in the tachogenerator itself.

Solutions:

the electrical circuit is checked and the resistance of the contact connections is measured,
the sensor mount is restored,
capacitor is replaced,
if necessary, the tachogenerator is replaced.

Electrical problems

Several codes indicate such problems.

i50 (5 blinks of the light bulb). In this case, the pump control thyristor is faulty. The occurrence of a malfunction is often caused by voltage drops in the network or overload from the signal from the control board. To fix the problem, it is recommended to check the functionality of the board or replace the thyristor.

i80 (8 flickers). The code indicates a malfunction in the functioning of the memory block. The device generates an error due to a failure in the firmware or a malfunction of the control module. To make the code on the display disappear, you must flash or replace the module.

i90 (9 flickers). Problems with the functioning of the electronic board. In this case, only replacing the failed electronic unit will help.

iA0 (light warning - 10 flickers). The code indicates a malfunction in the fluid spray system. Sometimes such problems occur due to the user's fault, for example, when dirty dishes are placed incorrectly. The device also issues a warning when the spray arm stops rotating. To eliminate the error, you need to check the correct placement of dirty dishes and replace the rocker.

iC0 (12 light flickers). Indicates that there is no communication between the board and the control panel. The malfunction occurs due to a breakdown of the electronic board. To fix the problem, you need to replace the failed unit.

In most cases, identified faults can be eliminated with your own hands.

Electrical faults

You must be careful with the electrical part of the equipment. Repair work must not be carried out while the power supply is on.

If electrical problems arise, the dishwasher displays Electrolux error codes:

1. i50 - malfunction of the control triac of the circulation pump (signal in the form of 5 blinks). The failure occurs due to voltage surges, a low quality thyristor, or an overload from the signal from the control board.

To solve the error (e 50 or i 50), you should check the functionality of the control board, or replace the thyristor.

2. i80 - malfunction of the external memory unit (warning - 8 blinks). The cause of the malfunction may be a firmware failure or a breakdown of the control module.

To fix the problem, you need to reflash or replace the control module.

3. i90 - the electronic board is malfunctioning, it is impossible to select and install the program (accompanied by 9 blinks). A problem occurs due to a firmware violation. To eliminate it, you need to change the electronic board.

4. iA0 - the water spray system is faulty (warning - 10 flashes). The problem may occur as a result of the dishes being loaded incorrectly, or the spray arm has stopped rotating.

Has your equipment been blocked and an error code appears on the display? This is how the self-diagnosis system reports a problem. The faster you decipher the symbols of Electrolux dishwashers, the sooner you will find out the cause of the breakdown. In the table below you will learn how to find and fix the problem yourself, and in which cases it is better to contact a service center.

Errors in electrical stuffing

These are the most difficult faults to diagnose in Electrolux dishwashers.

Error code i50 Five blinks of the end indicator indicating a triac failure. This part is responsible for controlling the circulation pump. First the problem forces it to work at its maximum capacity, and then the work stops. This error can be eliminated only after replacing the triac.
Error code i70 Seven blinks - the thermistor in the heating element is broken. This results in washing dishes with cold water. Installing a new thermistor will correct this situation.
Error code i80 Eight flashes - a problem in the memory of the control module. The problem can be solved by flashing the module or replacing it with a new one.
Error code i90 Flashing nine times - critical failure in the MCF or CCF checksum system. The situation is accompanied by blocking of all washing modes and the glow of the power indicator. The problem is resolved after replacing the module with a new one.
Error code i A0 Flashing ten times - stopping the rotating rocker arms. As a rule, it is caused by jamming after power surges. The problem may also be caused by incorrect placement of the dishes.
Error code iB0. Flashing ten times - the indicator indicating the transparency of the liquid is most likely broken. A malfunction is caused if there is no response from the sensor within 15 - 40 seconds.

Above are the most common signals about problems that may occur. The ability to decipher them is necessary to provide timely repairs and simplify diagnostic procedures. Most of these breakdowns can be fixed on your own, but calling a specialist will never be a bad idea.

Electrolux dishwasher fault codes

According to service centers, more than 40% of problems with the Electrolux PMM occur in the drainage and intake of water. Often such problems arise due to improper operation of equipment. Testing your dishwasher yourself helps you understand where to look for a breakdown.

If the error code appears on the screen for the first time, try to solve the problem by rebooting. Cars without a display indicate a problem by flashing the indicator. If this is a system failure, which often happens during a sudden power outage, the code will disappear from the display.

Error codes due to heating problems

Most often, users encounter water heating problems. Problems with heating will be indicated by code i60 (or 6 light flickers on the control panel). In this case, the water can either overheat or remain cold.

The i60 code is displayed due to:

The code i70 displayed on the display indicates a breakdown of the thermistor (in this case, the light on the control panel will blink 7 times).

The problem most often occurs due to burnout of contacts during a short circuit. The part needs to be replaced with a new one.

Problems with water heating

The i60 designation makes it clear that one of several problems is possible:

The heating element has failed; the temperature sensor is faulty; the cable wiring coming from the computer is damaged; The control triac in the control unit does not work; the circulation pump is broken; There is too little liquid in the reservoir.

If you have the skills to work with tools, you can replace the heating element or thermistor with your own hands. But troubleshooting wiring and ECU problems is best left to an experienced specialist. A malfunction of the thermistor is indicated by the i70 combination on the dishwasher display.

Inspect the rocker arm. Remove debris.
Remove half of the dishes from the tank. There may be a large plate that is preventing the sprayer from rotating.

In addition to codes, problems can be detected by indirect signs. In this case, the operation of the dishwasher is disrupted.

Elimination of breakdowns associated with blockages, collection and drainage of water

Possible reasons for the i10 error to appear are as follows:

there is no water in the water supply or the ball valve for its supply is closed at the inlet; the inlet filter is clogged with debris; the inlet hose has become kinked; the inlet valve does not open.

To eliminate the damage, check the presence of water in the water supply and the condition of the above parts. The filter needs to be cleaned, the hose needs to be straightened. It is easy to purchase and replace the fill valve yourself, or call a specialist to diagnose and repair the part.

Error i20 in an Electrolux dishwasher indicates that one of the following problems has occurred:

the drain filter is clogged; the impeller of the drain pump is blocked by debris; a blockage has formed in the drain pipe or hose; The water level sensor in the tank does not work.

Filter element in Electrolux dishwashers

First of all, you need to clear the filter of debris, then check to see if the pump impeller is jammed with broken dishes or debris. To do this, remove the pump cover located under the filter. A kink in the drain hose is also easy to fix. If the above steps are completed and the water still does not drain, you will have to replace the pressure switch.

The alphanumeric combination i30 on the display indicates the activation of the Aquastop system. Possible causes are damage to the tank, one of the pipes, hoses or their connections. In this case, the inlet solenoid valve immediately shuts off the water supply to avoid flooding. It may be necessary to completely disassemble the PMM for repairs, so it is better to call a specialist to your home.

Inlet hose with valve controlled by the Aquastop system

IF0 is another Electrolux dishwasher fault code, informing the user that water is being drawn into the reservoir very slowly. In this case, the machine will wash tableware with less liquid. Eliminating such an error is simple - after the wash cycle, drain the water, add it again, and the emergency coding will disappear.

In the 19th century, washing ladies' toilets took a lot of time. The dresses were first ripped open, and then each part was washed and dried separately so that the fabric did not become deformed. After washing, the clothes were sewn again.

The expression “soap opera” (“soap”) did not arise by chance. The very first series and shows that had a female audience were broadcast on television at a time when housewives did cleaning, ironing and laundry. In addition, to attract female viewers to the screens, commercials for detergents: soaps and powders were often played on air.

The first officially patented washing machine was made of wood and was a box with a frame, half filled with wooden balls. Laundry for washing and detergent were loaded inside and the frame was moved using a lever, which, in turn, made the balls move and grind the laundry.

Washing machines have something to do with the origin of the expression “money laundering.” In the 1930s, American gangsters used a network of laundries as a cover for their illegal activities. By passing off the proceeds of crime as proceeds from cleaning clothes, they turned “dirty” money into “clean” money.

There are a variety of balls that are used in the washing machine. Antistatic ones will prevent the fabric from sticking to the body after washing, balls with special loops will “comb” the lint and prevent the appearance of pills, and silicone ones with pimples will prevent fluff from matting when washing outerwear.

History knows the fact that a kitten fell into the drum of a washing machine and, after going through a full wash cycle on the “Wool” program, got out of the unit unharmed. The only trouble for the pet was an allergy to washing powder.

Washing machines equipped with the “No Iron” or “Easy Iron” functions can wash clothes with little to no wrinkling. This effect is achieved through a special approach to spinning - it is performed at low speeds, with long pauses, and a small amount of water is retained in the tank.

There is a washing machine “for bachelors”. Linen washed in such a unit does not need to be ironed at all! The thing is that the device does not have a drum: some things can be placed inside the container directly on hangers (for example, jackets and shirts), and smaller things (for example, underwear and socks) can be placed on special shelves.

Astronauts, while in Earth orbit, solve the problem of dirty things using an original method. Clothes are dropped from the spacecraft and burn up in the upper atmosphere.

Electrolux dishwasher errors: fault codes i30 and i20, i10 and i40, i60 and i50, signals and their interpretation, Error codes for Electrolux dishwashers.

Error coding and their types

Modern types of dishwashers are distinguished by increased functionality, including the ability to perform self-diagnosis. This is a useful feature that helps prevent most serious damage. Based on alerts in the form of error codes, the user can monitor the status of the machine directly from the device display, for example, determining that the dishwasher is not finishing the program.

Each error has its own meaning and description. There are several general categories into which errors are classified:

Problems with water heating (For example, error e03);
Malfunction in the process of draining and filling water;
Problems with the water switch and sensors;
Electrical problems.

By deciphering the error code in a timely manner and reacting, the user can fix most problems on his own, without involving a technician and without significant financial costs.

The meaning of brand equipment fault codes

Many Electrolux dishwasher models are equipped with a self-diagnosis system; they issue a code that can be used to immediately determine the cause of the problem. The message is displayed on the monitor in the form of an error code, for example i60 or i20, etc. If there is no separate display, problems are indicated by a flashing END indicator.

Problems with collecting, draining or heating water are most common.

Here are the codes for them:

i10 occurs if no water flows into the dishwasher chamber within a minute from the start of the cycle, it is recommended to check the condition of the tap, hose (perhaps it is simply pinched), and also clean the filters at the water inlet to the dishwasher;
i20 shows that there are problems with the drain, you need to check and clean the drain filter and drain hose, as well as the drain pump and water level sensors, damaged elements will have to be replaced;
i30 indicates that leakage protection is turned on; you need to drain the water accumulated in the pan and restore the position of the float sensor or replace the hose in the mechanical version of the Aquastop system;
iF01 indicates that water has been entering the chamber for too long, usually this error corrects itself after the end of the washing cycle, it would not hurt to check the water supply system to carry out preventive work;
i60 - a signal about the absence of water heating or about significant overheating, which happens if the heating element has burned out, there is a breakdown in the electrical circuit, the circulation pump, temperature sensor or control board has broken down.

Options for eliminating i60 type breakdowns were described above. In the following video you can watch the repair of a built-in dishwasher that generated this error:

Overheating may occur if there is not enough water inside. In this case, you need to follow the recommendations for the situation with the i10 stake.

The following codes indicate serious electrical, electronic and other similar problems:

i50 – circulation pump triac is broken;
i70 – the heating element thermistor is damaged;
i80 – problems with the control module firmware;
i90 – a malfunction of the control board, which does not allow you to select the operating mode of the device.

Replacing a damaged triac or thermistor is relatively easy. But to reflash or replace the control module, you will have to contact a service center.

Other common problems with Electrolux dishwashers include the following codes:

iA0 indicates that there is no rotation of the indicator rockers, usually this is due to improper placement of dishes in the chamber or due to a voltage drop;
iB0 – transparency sensor failure;
IC0 – lack of communication between the panel and the control board;
id0 – the tachogenerator of the circulation pump is broken, the water does not heat up.

This type of breakdown is complex; you will have to use the help of a service center. Failure codes do not always accurately describe the problem that has arisen in the operation of the dishwasher. It happens that a malfunction occurs due to violation of operating conditions or for some other reasons. If this factor is not eliminated, breakdowns will occur again.

Prevention

Any appliance, including a dishwasher, may have problems with its operation. These could be either software glitches or technical malfunctions. To prevent most of these troubles, the user should carry out regular preventive maintenance. This involves performing the following steps:

It is recommended to always check the inlet water temperature. The optimal value is 50°-60°;
It is necessary to monitor the amount of rinse aid in the dishwasher and prevent its shortage;
Regular cleaning of filters is required;
Follow the rules of operation, including the principles of arrangement of utensils;
Protecting the dishwasher from power surges;
To prevent the occurrence of unpleasant odors inside the machine, the door should be left half open.

Some work should be carried out with the machine completely disconnected from the power supply and water supply. This will ensure the safety of the user, and is also confirmed by the requirement of the service rules.

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.

Control system malfunctions

If such breakdowns occur, diagnostics and repairs should be carried out by qualified technicians. For example, if the circulation pump does not work (error i50), the reason may be either the pump itself or the failure of the control triac located in the control unit. In addition, the triac may not receive a signal generated by the processor. Similar situations may arise when codes from i80 to iD0 are displayed, when the sensors do not respond or the ECU is broken.

Electrolux dishwasher control unit

We looked at the most common breakdowns of Electrolux dishwashers. We hope that this material will help you troubleshoot problems yourself.

Problems with the heating element

If you notice that the water in the dishwasher is not heating up enough, then most likely there is a problem with the heating element, or with the temperature sensor or other control modules. Electrolux dishwashers are quite sensitive to voltage fluctuations, as well as to oversaturation. What could this lead to?

In the best case, you will get away with a blown fuse; in the worst case, several triacs on the control board may burn out. After this, the control module simply will not be able to send signals to the heating element, or will do so with a delay or perform it incorrectly. Repairing a malfunction that has occurred is quite a labor-intensive and expensive task. You need to:

disassemble the dishwasher in half in order to get to the heater;
check the integrity of the wires going to the heating element and measure the resistance using a multimeter;
Check the parts of the control module, if a malfunction is detected, replace with a new one.

We would like to note that in order to protect household appliances and other devices from voltage surges, you can use a voltage stabilizer, which is purchased separately.

If you do not understand this topic, the best solution would be to call a specialist who will accurately diagnose the breakdown and fix it as soon as possible.

The washing program is stuck

Various errors can occur during operation of the dishwasher, and the most common problem is the washing program freezing. As a result, the user may need to reload the dishwasher. Most errors have their own codes (for example, error code i30, e4, e03, e09 and others), the interpretation of which can be easily found in the manual, and brief information is displayed directly on the screen.

System failures are described in the control module program, this includes the program of the popular Bosch dishwasher. This allows self-diagnosis and alerts the user about various problems. Often the error that occurs does not disappear even if the device is rebooted or turned off and then on. The only solution to such a problem is to determine the cause and completely eliminate it.

The program freezing error can be caused by a variety of reasons. However, this often happens when the user does not perform regular cleaning and maintenance. As a result, the filters can become clogged, then the sensors are triggered, and the control module can block the operation of all machine components. This will continue until the blockage is completely cleared.

It happens that during operation a certain number of errors of various types accumulate. They are insignificant and do not interfere with operation, but after a certain time the machine may begin to malfunction or may not start on the first try, which can lead to serious breakdowns in the future.

Those who are wondering how to reset accumulated errors should press a certain combination of buttons and perform some actions.

The dishwasher does not complete the wash program

A fairly common occurrence is that during a washing program it simply freezes. Most often, to solve the problem, you need to reboot the dishwasher; to put it simply, you need to turn off the device for just a couple of minutes, and then return the power supply to it again.

If this problem repeats with all dishwashing programs, you must call a specialist who will carefully check everything and, if a defect or defect is found, replace the damaged part.

Note! On some Electrolux dishwasher models, replacing the control module costs a lot of money. In such a situation, it will be easier for you to buy a new dishwasher than to replace a faulty control module

However, do not be upset, this problem is most often associated with an error in the operation of the following sensors, namely: pressure switch, aqua sensor and others. Sometimes the electrical network is involved in the failure of the entire group of sensors.

In this article we looked at how to repair Electrolux dishwashers with your own hands. However, remember, if you don’t know anything about technology, the best solution would be to turn to specialists who will carry out all the repairs themselves, and you won’t have to waste your nerves and money on unjustified actions.

Electrolux dishwasher error codes

Modern science and technology go hand in hand, constantly improving. Just recently, no one would have thought that self-diagnosis systems would be able to display error codes on displays for dishwashers from Electrolux, Zanussi, AEG and other well-known manufacturers. And now service center technicians and ordinary users can understand by the blinking of LEDs or the information code displayed on the display what malfunction has occurred in the dishwasher (hereinafter also referred to as PMM, dishwasher).

When a specialist goes to repair a dishwasher and knows its error code, he immediately takes the necessary spare parts with him

A decoding of the alphanumeric combinations appearing on the displays is in the instructions attached to each PMM. Therefore, many operational problems can be eliminated independently. In more complex situations, it is better to call a specialist for repairs at home. Below are the coded fault signals and their interpretation.

Fault code i20 in the AEG dishwasher indicating no water draining

Electrolux PMM error codes and how to fix them

Electrolux dishwasher errors have their own codes, which are displayed on the control panel on the screen (as on the ESL47700R model). In models without a display (for example, model ESL 96211 LO), fault notifications are carried out using light signals - sequential flashing. In some models, a warning about problems is displayed both on the screen and by flashing indicator lights.

If your dishwasher is having heating problems, one of the following symbols may appear on the display:

1. i60 - the water does not heat up at all or overheats (warning in the form of 6 flashes). The causes of the problem may be:

Solving the problem with error i60:

2. i70 - the thermistor is faulty, the heating element stops working and heating the water (signal - 7 flashes). The cause of the malfunction is burnt out contacts (most often as a result of a short circuit). To fix the problem, replace the thermistor.

Fault coding and interpretation

The table shows combinations that readers may encounter while operating Electrolux and Zanussi PMMs. In most models that do not have a display, failure is determined by the number of blinks of the End indicator. A series of flashes occurs at a frequency of 2 Hz, followed by pauses between series of 5 seconds. The error codes listed below are valid for modern Electrolux and Zanussi PMM models with EDW 1003/1100/1500/1503/1510/2500 control systems.

Number of indicator flashes

For a certain time, a sufficient volume of water from the water supply does not collect into the tank or it does not enter the dishwasher at all

After a certain time, the liquid from the tank is not completely drained by the pump into the sewer system or is not removed at all, that is, the water level sensor (pressostat) does not receive a signal about the empty tank

The Aquastop protection system sensor sends a signal that water has appeared in the dishwasher tray. This means there is a fluid leak.

The triac located on the control unit board (hereinafter also referred to as the ECU) has failed, resulting in the control of the circulation pump (pump) being disrupted.

The water does not heat up or overheats. There may be several reasons: the electric heater (hereinafter also referred to as the heating element) burned out, there was a break in the electrical wiring circuit going to the heating element, the temperature sensor (thermistor) is faulty, there is too little water in the PMM tank. The circulation pump may have stopped working or the ECU may be faulty

The thermistor is faulty; its resistance during diagnostics does not correspond to normal limits

Failure in the program stored in the memory of the control unit. The EEPROM memory chip may have failed

The PMM control unit does not work, as a result of which it is impossible to select and launch any of the work programs

The sprayer rocker arms are blocked and do not rotate. Possible reasons: the dishes were not stacked correctly or there was a power surge that led to a blockage

The water turbidity sensor has failed. The control unit constantly receives information that the dishes have not been washed

The computer does not respond to signals from the control panel. Maybe there is no connection with the control unit board or the unit itself is faulty

When the circulation pump is turned on, the tachogenerator does not send signals about rotor rotation for a certain time. Possible reasons: the pump really does not work, there is a break in the tachometer circuit or the tachogenerator is faulty

During a specified period of time, a sufficient volume of water has not filled into the dishwasher tank and the unit proceeds to the next stage of operation. After draining the liquid, the error code disappears. Symptoms of the malfunction are similar to defects corresponding to code i10

If there is no display, the error code is calculated by a series of flashes of the END indicator

Be careful when recognizing the number 1 and the letter i on the display: the unit is longer .

“Weak points” and failure codes of famous brands

Today, many dishwashers from well-known world manufacturers, even in the budget category, are equipped with an automatic system for diagnosing violations and breakdowns. It uses codes - when a malfunction is detected, the machine displays the corresponding code on the screen. Moreover, each manufacturer uses its own designation system.

Electrolux

According to user reviews and the opinion of repair technicians, Electrolux dishwashers often have a problem with water leaking onto the floor. This happens as a result of damage to the seals and the parts themselves through which the liquid flows. To signal the car, they are equipped with a tray; when water gets into it, the code i30 is displayed on the display, and the LED starts flashing three times.

Error codes:

i10 – water is not pumped into the chamber;
i20 – water drainage is difficult or does not occur;
i30 – overflow or leakage;
i50 - short circuit of the pump triac;
i60 – heating system violations;
i70 – short circuit or break of thermistor;
i80 – communication error with firmware;
i90 – the programming model is broken;
iA0 – sprinkler blocking;
iB0 – transparency sensor does not work;
iC0 – connection with the user interface is lost;
id0 – no signal is received from the tachogenerator;
iF0 – water supply time error.

Hotpoint-Ariston

Despite the fact that the Ariston brand is one of the most reputable in the household kitchen appliances market, it also has its own typical malfunctions that occur most often. Excluding cases with clogged filters and working mechanisms, it can be noted that Ariston’s heating element often fails, due to which it either gets plugged or the dishes are poorly washed. Also on the list of frequent faults: breakdown of the water level sensor, filling valve and drain pump.

Ariston machines use the following code system:

AL01 – the Aquastop system was activated due to a leak;
Al02 – the flow of water into the tank is difficult or does not occur;
AL03 – draining is difficult or impossible;
Al04 – power supply to the temperature sensor is interrupted;
AL05 – water level sensor or circular pump is faulty;
AL06 – the power supply circuit of the filling valve is broken;
AL08 – an error signal is received from the temperature sensor;
Al09 – keyboard malfunction or electronic module program failure;
AL10 – the power supply circuit of the heating element is broken;
AL99 – no connection due to problems with the electronic module or cable.

Bosch

Typical malfunctions of Bosch dishwashers include:

The machine does not turn on when the water and power supply are correct. Most often, the reason lies in a malfunction of the start button or door lock.
Water leaking onto the floor. Here, damage to the hoses, clogging of the filter, and failure of the level sensor are observed.
The device does not wash well due to low pressure on the spray arms. Often the problem can be solved by cleaning it yourself.
Electronic control board failure. In this case, you cannot do without the services of a specialist - the unit will have to be replaced.

Error codes:

E01 or F01 - failure in electronics and electrical, quite often - damage to the heating element;
E2 or F2 - temperature sensor malfunction;
E09 (F09) – malfunction of the flow heating element;
E11 (F11) – lack of power to the temperature sensor;
E12 (F12) – a large amount of dirt or scale (some models signal this error with code E09 after a reboot);
E3 (F3) – water does not fill;
E5 (F5) – tank is full;
E8 (F8) – the circular pump cannot turn on due to the fact that the machine does not draw the required amount of water;
E16 (F16) – the dishwasher cannot stop pouring water into the chamber;
E17 (F17) - a narrow-profile error that says that the intake valve does not close as expected due to high pressure;
E21 (F21) – errors in the operation of the drain pump with normal power supply and sensor operation;
E07 (F07) – the hole through which water is pumped out is blocked (by garbage or improperly stacked dishes);
E22 (F22) – one of the filters is clogged;
E24 (F24) – water does not drain due to a clogged sewer or drain hose, if the hose is kinked or the siphon is blocked;
E25 (F25) – the pump pipe or drain hose at the base is clogged; E4 (F4) – the water supply control sensor is faulty or not working properly;
E6 (F6) – the water purity sensor is broken;
E14 (F14) – the sensor for controlling the amount of water in the tank is not working correctly;
E 15 (F15) – an error occurs on models with the Aquastop system when there is a leak;
E27 (F27) – voltage drops in the supply network, you need to connect the machine through a stabilizer.

Troubleshooting common problems

According to statistics from service centers, almost half of all violations in the operation of dishwashers are due to the lack of filling and draining of liquid due to violations of the operating rules of the PMM.

Sometimes error codes appear for no reason due to ECU malfunctions or power surges. To eliminate them, follow these simple steps:

disconnect the dishwasher from the power supply by removing the plug from the socket;
wait 20 minutes;
connect to the network and turn on the PMM again.

Quite often, the code combinations of breakdowns disappear after this, and the machine continues to work without failures.

Causes and procedures for eliminating problems with water filling and draining

Liquid may not enter the PMM for the following reasons:

there is no water in the tap;
the tap located in front of the inlet hose is closed;
a blockage has formed in the inlet strainer;
the inlet hose is bent;
The solenoid inlet valve is faulty.

All of the above defects (error i10), except for the breakdown of the intake valve, can be eliminated on their own. If you do not have a multimeter, it is better to entrust the diagnosis and replacement of the valve to a specialist. Another code combination associated with slow water intake is iF0. More detailed information about repairs in case of lack of water supply can be found here.

If the machine starts working after filling with water manually, then the reason it stops is that there is no liquid flowing

The occurrence of drainage problems and the corresponding i20 error in an Electrolux dishwasher also have various sources:

coarse and fine filters are clogged with food debris and grease;
The drain pump does not work;
the pressure switch has failed;
Is there a blockage in the drain hose?

Food debris or glass shards can get into the sump pump impeller, jamming its rotation.

Why does the i30 error code appear in the Electrolux, Zanussi PMM and how the Aquastop system works, see the following video:

Problems with water heating

The absence of heating is reported by the code combination i60. The reasons for its appearance are listed in the table above. It is better to entrust wiring diagnostics and ECU testing to a qualified technician. You can replace the heating element and thermistor on your own if you disassemble the PMM housing (if you have a multimeter for testing the heating element and temperature sensor). If the electric heater circuit is broken, it must be replaced. The thermistor failure is reported by error code i70.

Knowing the decoding of code combinations, most malfunctions in the operation of the PMM can be eliminated with your own hands if you have the appropriate tool and skills in handling it.

The dishwasher does not wash with hot water. What to do if the dishwasher does not heat the water

If, at the end of the program, you take dishes out of the tank that are dirty and cold to the touch, this means that the dishwasher is not heating the water or is not heating it well enough, and is not drying it either. It’s too early to sound the alarm, because some failures due to which the water does not heat up can be eliminated without the help of a specialist:

The machine is being used for the first time. Perhaps the equipment is installed incorrectly, which is why water is constantly being collected and drained, so the heating element does not have time to warm it up, the heating time is increased. To fix the problem, ask a specialist to connect the dishwasher correctly or do it yourself, following the installation instructions.
Wrong mode. There are cycles in which the water does not warm up above 40 degrees (with delicate washing). There is a problem in the electromechanical type PMM: when the program is set to 30 degrees, and the position of the selector wheel is at the temperature level of 90, the washing will proceed according to the selected program; the water will not warm up above 30 degrees. Information about the modes can be easily found in a separate article or in the user manual.
When the filter is clogged, water circulation decreases, which is why the heating element does not start and does not heat the water. You need to clean the filter and add this procedure to the list of regular household chores, otherwise the PMM will still wash your dishes with cold water - and this is a waste of time, detergents, and resources: water and electricity.
