Error codes for Electrolux washing machines: decoding

Most models of household washing equipment from the Swedish concern have displays that display the current state of the unit. This convenience allows you to equip automatic washing machines (hereinafter also referred to as SMA, SM) with additional service capabilities. In case of malfunctions, error codes of Electrolux washing machines are displayed on the display screens. They allow owners to localize the breakdown and, in some cases, fix it themselves or report the code to the service center. Then it will be easier for the technician to figure out which unit might have failed.

The error code displayed on the display allows you to localize the fault and speed up repairs

The Electrolux group of companies produces washing equipment under three brands, which also include the well-known brands Zanussi and AEG. To optimize the production process, most parts in these units are identical. The fault codes are also the same. Error codes for Electrolux washing machines are alphanumeric combinations starting with a letter of the Latin alphabet. Almost all of them have the letter E at the beginning (from the English error - error). Let's look at typical faults and their codes.

Failures associated with water entering the drum

Problems in the operation of units associated with the lack of water in the tank are common among Electrolux models - for example, such as the W4180H. Given that the quality of tap water leaves much to be desired, large amounts of sediment can often be observed deposited in hoses, filters and drain pumps. This makes it difficult or stops transporting water into or out of the tank.

Error E10 in Electrolux washing machines is one of the most common

Error E10 in Electrolux washing machines, as well as E11 in some models, indicates that there are certain problems with the intake of liquid into the drum: water does not flow or its pressure is so low that the level does not reach the optimal level in the allotted time.

First, the most obvious causes of the error are checked - maybe there is simply no water in the water supply.

During diagnostics, the pressure in the inlet line through which the liquid flows is checked. Often the water in our houses is turned off or the owners turn it off themselves and then forget to turn it on. Therefore, such reasons are quite common. In addition, the inlet hose and filter are checked for clogging.

The intake valve may not open due to the lack of a control signal or due to a broken winding in the electromagnet (possible error EC1 ). You can check the winding with a multimeter - if it is working properly, the device should show a resistance in the range of 3.6–3.8 kOhm. The electronic control unit (hereinafter also referred to as ECU) contains symmetrical thyristors - triacs (hereinafter also referred to as triacs) that control the valves. If there is a malfunction in this unit, water will not flow into the tank.

All of the above breakdowns can be eliminated by cleaning the intake manifold and clogged parts or replacing faulty elements.

Let's start with the obvious problems

If the washing machine issues an EFO code, the first step is to eliminate obvious causes of the error. They can be assessed with the naked eye. Perhaps we are talking about excessive foaming in the washing machine drum. Make sure that you put automatic washing powder in the tray and not manual detergent.

Modern Electrolux technology is very sensitive to the level of foam, and it is increased foaming that can cause an error.

If the fault code is displayed very often, but still not with every wash, it may be the issue with the amount of detergent. Try to load exactly as much powder into the tray as is recommended by the standards. The washing machine may react sharply to an overdose of detergents and show an EFO . It is also a good idea to thoroughly rinse the washing machine dispenser.

Problems draining liquid from the tank

If error E20 on an Electrolux washing machine, this means that water has not been removed from the SM within a time period of 10 minutes or more. A breakdown can be indicated by codes E21 , C2 , E23 , EF0 and E24 .

EF1 may indicate that the drain time has been exceeded . EF2 combination indicates an increased level of foaming, which may also be due to a clogged drain line. Error EF3 indicates a leak in the pump or damage to its wiring, leading to the activation of the Aquastop system.

First of all, the problem should be looked for in the sewer and drain hose - they may be clogged. In addition, you should check the filter located in front of the drain pump; there may also be a blockage there.

You can check and clean the drain filter in your washing machine yourself.

The cause may also be a malfunction:

• drain pump - error E85 ;
• triac that controls the operation of the pump - codes E23 and E24 ;
• other elements of the electronic control unit.

The resistance of the winding that drives the pump should be around 200 Ohms. If its value is very different, the pump will have to be replaced.

Intuitive repair

What should I do if the display shows code E90? First of all, it is recommended to check the garbage filter and drain hose for blockages. If nothing is found, do not rush to remove the pump from the housing. Try the following:

• remove the top cover of the washing machine by unscrewing the two fastening screws;
• take a hairdryer;
• Dry the command device and all contacts connected to it thoroughly.

It takes a long time to dry the part. After completely removing moisture from the module, there is a high probability of eliminating error E90. If this measure does not help, you will have to inspect the drain pump. If the pump is in full working order, it is better to contact a service center, where a technician will diagnose the main control module and repair it.

Malfunctions related to the pressure switch

This device is also called a water level sensor or pressure sensor. The overall performance of the SMA depends on its proper operation. For example, if the sensor is faulty, the laundry spin mode may not turn on or the washing mode may start prematurely.

If the pressure switch is not working properly, you can clean the tube or replace the sensor yourself

Code E30 informs that the sensor is not configured correctly and reports an incorrect amount of liquid poured into the tank. The main reasons for such failures are:

• clogging of the tube through which the pressure created by the flooded water in the tank is supplied;
• setup failure;
• failure.

Another possible reason is unstable mains voltage.

Inconsistency between the operation of the water level sensor and the relay that controls the operation of the heating element - heating element - is expressed by the appearance of code E33 . The best solution to the above problems is to install a mains voltage stabilizer, clean the tube or replace the sensor.

Error E31 informs you that the sensor is not working. A faulty part is also one of the reasons for error E32 . You can check the pressure switch yourself. To do this, you need to connect another tube of the same diameter to it and blow strongly into it several times. If you hear clicks at this time, it means that the device may be working properly and the problem lies not in it, but in the wiring to the control unit. A more correct diagnosis is to check the resistance of the pressure switch winding while air is blown into it. If at the specified moment the resistance level does not change, the sensor must be replaced.

Similar checks should be carried out when code E35 , which informs that the amount of liquid in the tank is exceeded. This means that the operation of the water level sensor is disrupted and it did not send a signal to turn off its supply. Error E38 signals the absence of information coming from the sensor to the ECU, and also requires checking the connecting circuits.

Problems with the operation of the hatch covering the tank

Such breakdowns are among the most common. Error E40 in an Electrolux washing machine provides information that the door is not closed. E41 also informs about this . The door may be ajar for the following reasons:

• not pressed enough when closing;
• the lock blocking the hatch is faulty ( E42) ;
• there are problems with the locking system;
• laundry got into the gap between the tank and the door;
• The rubber gasket sealing the hatch is damaged or deformed.

Malfunctions associated with malfunction of the hatch door are unlikely to be resolved independently

Code E43 indicates that a breakdown of the triac that controls the operation of the lock has been detected. E45 combination indicates that the fault lies in the electronic parts and circuits that control the operation of the triac and lock. The causes of these problems are located in the control unit, as well as in the connecting wires and connectors. Coding E44 informs about a malfunction of the sunroof closing sensor. This can be “cured” by checking the connecting circuits and replacing the faulty part.

Error code E40 indicates a malfunction related to the lack of fixation of the hatch door

Problems related to the operation of the electric motor

The electric motor that rotates the drum is the most important component of the washing machine, so any malfunction is critical and will affect the performance of the washing machine.

Error E50 informs about a whole range of possible problems associated with engine malfunction. These include:

• breakdown of the triac that controls the engine;
• incorrect operation of the tachogenerator, which provides information about the engine speed;
• malfunction of the control controller in the ECU;
• malfunction of engine bearings.

It is better to entrust diagnostics of the electric motor and its control circuits to qualified technicians

Code E51 specifies the breakdown, indicating a non-working triac. E53 signals an open circuit between the triac and the electric motor. The combination E55 lets you know that there is an open circuit in the motor circuit. E52 , E56 and E59 washing machines indicate the absence of signals that the tachogenerator should send. The reasons may vary. In the first case, the fixation of the Hall sensor washer is broken: most likely, it has jumped out of place. Other options are a malfunction of the tachometer, connecting electrical circuits and control board.

E54 signal suggests that one of the relays that controls the reverse rotation of the engine is not working - it is stuck or the control circuits are faulty. E57 signals that the permissible current consumed by the washing machine has been exceeded. The cause may be a short circuit in the motor winding or in the electrical wiring of the MCA. The above short circuit in the engine, as well as a malfunction in the ECU, can lead to the appearance of error code E58 .

Operating errors associated with the heating element (heater)

The heating element is one of the main parts in a washing machine. It often breaks down or works incorrectly. One of the common reasons is the formation of scale on pipes due to the high content of calcium and magnesium salts in the water.

In the photo you can see scale on the heater, formed due to too hard water

If the heater does not heat the water well, the SM lets you know about this with code E60 or E61 (in some models these errors can only be seen in test mode; they may not be displayed during operation). The reason is scale formation or a malfunction of the heating element. It can be checked with a multimeter - in working condition, the resistance of the heating coil is in the range of 30–40 Ohms.

Error E62 informs you that the water is heating too quickly and too much. The probable cause is a malfunction of the temperature sensor, which will need to be replaced. Codes E66 and E3A warn that the relay that controls the operation of the heating element is not working. In addition to a faulty relay, the problem may be in the control circuits. Combination E68 reports high leakage current. The cause may be a faulty heating element or ECU.

Code E36 signals a failure of the protective relay that prevents the heater from turning on in the absence of water. Codes E70 , E71 and E74 are related to the temperature sensor (NTC) not working properly. Error E70 signals an open circuit in the sensor circuit, E71 indicates that the NTC is not working properly and needs to be replaced. The appearance of the inscription E74 indicates that the position of the sensor has been violated and it is necessary to return it to its seat.

Conclusion

Electrolux washing machines have a fairly wide range of different problems. It’s just that washing equipment contains a very large number of elements, which means a large number of possible breakdowns. The manufacturer tried to provide for everything, so most of the codes exist only on paper. Most often in washing machines, the heating element or electric motor of the washing machine fails. You can repair these elements yourself at home.

With some skills, you can also replace or check the sensors. But in matters related to the electrical board, relays or checking electrical connections, it is better to contact a professional. Even experienced repairmen often give in to problems with the control circuit, and an attempt to solve the problem on their own can lead to complete breakdown of the machine. Well, or to a state when it will be cheaper to buy a new washing machine than to repair an old one. In any case, the final decision is up to the owner of the unit.

Codes of other breakdowns of Electrolux CM and their interpretation

Below is a table that reflects other error codes for Electrolux washing machines - combinations of letters and numbers displayed on the display and indicating certain breakdowns that may occur during operation.

Electrolux SMA error table: meaning and solutions

Error indication in washing machines without display

Not all SMAs have displays that can visually display the status of their operation. There are models in which error codes for Electrolux washing machines are displayed by flashing certain indicators. SM of this type have two most common control modules - EWM 1000 and EWM 2000. Each of these modules generates faults in the same way, but they can be indicated differently.

The EWM 1000 module generates codes more easily. To view them, you need to press and hold two buttons in this state: “Start/Pause” and the additional function that is closest to the “Start/Pause” button for several seconds.

The EWM 1000 module usually has horizontal button layout

This operation can be carried out even during washing. First, the indicators located next to the pressed buttons will go out and then begin to flash according to the error code. The latest error code can be seen at any time if you move the selector to position 10 (diagnostic mode). The memory remembers this state of the SM.

The letter E is not displayed by indicators, since it is present in all combinations. Other letters, if present in the code, are displayed with flashes corresponding to the hexadecimal code:

• A – 10 blinks;
• B – 11;
• C – 12;
• D – 13;
• E – 14;
• F – 15.

The numbers are indicated by the number of light pulses from 0 to 9. If the code corresponds to, for example, EF5, this means that the first indicator will flash 15 times, and the second - 5.

Depending on the model, the EWM 2000 control modules have different designs, but the indication in them also corresponds to a hexadecimal code, the value of which is determined by the lit indicators in a group of four LEDs.

The indicators are arranged in order, from bottom to top, according to the table

How to read a signal

It just seems like a simple task. What’s so difficult, I looked at the display, checked the article, identified the error and corrected it. But it's not that simple. Firstly, there are both display and non-display options for controlling the Electrolux washing machine. And if the display panel simply displays an existing error code, then you will have to tinker with the option without a display.

If the Electrolux washing machine has an EWM 1000+ electrical board, then there are two options: the buttons are arranged vertically in one row or horizontally in two rows. For the first case, you need to press the two buttons closest to the selector and turn the selector by numbers from 1 to 8. Each number will mean its own block of errors, and the number of “blinks” of the LED will show the sub-number of the Electrolux error. Everything seems simple.

With two rows it is even more difficult; here, to enter the testing mode, you will have to hold the two upper plugs in the row farthest from the selector and also turn the knob for washing modes from 1 to 8. For Electrolux machines with the EWM 2000 system, the scheme is even more complicated and can be done without consulting a specialist It's unlikely to work.
