Error codes for AEG washing machines

error codes SM AEGAEG washing machines of the well-known brand have excellent technical characteristics, high build quality, and are distinguished by a wide range of functions and additions. The washing machines are equipped with a system for self-diagnosis of arising malfunctions - a large number of different machine error codes are programmed in the memory of the machine, which allows the user of the equipment to immediately find out about the failure in the device. Having recognized a malfunction, the electronic unit will instantly display an error symbol on the digital display.

The database of the self-diagnosis system contains about a hundred different fault codes, it is very difficult to keep in memory what each of them means. We will provide you with a detailed decoding of all the signs, this will help to correctly diagnose the damage and do the repair yourself.

Codes for discharge and flood of water

What to do when suddenly the machine stops functioning and notifies of a malfunction, displaying an unknown code on the screen. First you need to understand which element of the system is damaged. First of all, we will analyze the errors regarding the collection of water in the drum or the discharge of waste fluid from the unit.

  1. E11 - indicates that the automatic machine was unable for a given period of time to draw water into the tank to the desired level. The washing machine can display this designation due to a defect in the filler valve, violation of its winding, clogging of the inlet hose or filter installed at the system inlet. You can fix the problem on your own, for this you need to check the valve with a multimeter (the working element will show a resistance equal to 3.75 kOhm), clean the water intake hose and filter.
  2. E13 - informs about the leakage of water from the system. In most cases, fluid flows into the SMA pan. The unit should be examined for emergency leaks.
  3. E21 - tells the user that for a certain intellect time, the washer did not drain the waste water. The reasons for this failure can be several: damage to the pump, blockage of the drainage system, failure of the drainage pump, defect of the control board. You can diagnose the drain pump with a multimeter. When checking the pump winding, the tester should show a value of 170 Ohms.
  4. E23 - warns that a malfunction of the main triac located on the unit control board has been detected. You can reset this error code, you just need to check and change the triac, or change the control unit for the washer.
  5. E24 - indicates a violation in the connection "control triac - drain pump." To correct the situation, examine each section of the circuit, diagnose all elements using a multimeter.
  6. EF3 - signals the activation of the “Aqua Control” function. Another reason is open or damaged pump wires. You will have to replace either the pump or the pump cable.

Having figured out what problem appeared in the system, it will be easier to make repairs. The search for a broken part will instantly narrow down to one or two elements that will have to be tested.

Damage to electricians, electronics

In case of failures in the electronics, a certain group of codes can be seen on the scoreboard. Problems can be caused by both malfunctions of the main power supply network and damage to the wiring of the machine. Let us analyze the designations of this category.

  • E91 - informs about a communication failure between the control board and the interface of the washer. The way out of this situation is to replace the main control unit.
  • E92 - indicates an inconsistent operation of the user interface and the main control module.
  • E93 - indicates that the configuration of the washer is built erroneously. Correcting the inaccuracy will help by indicating the correct configuration code.
  • E95 - reports a violation in the circuit "processor - non-volatile memory of the washing machine."
  • E96 - signals an erroneous configuration of external parts (in particular the controller).
  • E97 - indicates that the washing mode selector knob cannot function in concert with the control module. Perhaps this is due to a configuration error or a malfunction of the main unit.
  • E98 - informs about inconsistent operation of the unit motor and control unit. Either replace the circuit wiring or replace the control board with a working part.
  • E9A - indicates a software violation between the washer electronics and the speaker. You can get rid of this code only by changing the main control module.
  • EH1 (EB1) - indicates that the mains voltage exceeds the permissible limit. There may be interference in the mains, or the power supply of the washing machine is not entirely reliable. If everything is normal, check the control unit.
  • EH2, EH3 (EB2, EB3) - errors inform the user about excessively high and low voltage in the mains, respectively. In both cases, a change of electronics will be required.
  • EHE (EBE) - indicates damage to the protective circuit relay.
  • EHF (EBF) - signals that the protective circuit could not be recognized.

Carrying out repair work related to the SMA electronics is best entrusted to a professional. An electronic module is the most expensive element of an automatic machine, therefore, without special knowledge and skills, it is better not to take it to repair.

Sensor Issues

Let's analyze the fault codes of the AEG washing machine, signaling some problems with various sensors. The main designations of this damage group are presented below.

  1. E31 - indicates the failure of the sensor level (pressure) of water in the tank. To correct the situation, you need to inspect the pressure switch and the contacts leading to it. If a wire break is detected, the connection should be repaired. When the sensor is broken, you will have to replace the pressure switch.
  2. E32 - indicates that the pressure switch is not calibrated. For example, after the initial calibration, the liquid level in the tank is greater than the 0-66 mm mark, while the level of anti-boiling is not achieved.
  3. E33 - warns that immediately three system sensors work inconsistently with each other. We are talking about a pressure switch, a level 1 sensor and protecting the heater from unauthorized switching on. There can be several factors leading to such a failure: damage to the elements, clogging of the nozzles. Also, E33 can be displayed with an overvoltage of the mains voltage, as a result of which the heater is leaking onto the SMA housing. Check the tube heater for breakdown, to do this, put the multimeter in buzzer mode and lean its probes against the surface of the element.
  4. E34 - signals an inconsistent operation of the connection between the pressure switch and the anti-boiling level sensor. If the designation appears on the digital screen for more than 60 seconds, the sensor should be replaced, the circuit contacts examined, if necessary, replaced or cleaned. You can try changing the sensor pipe.
  5. E35 - states that the tank is full of water. To solve the problem, check the water level sensor with a multimeter. If the pressure switch is defective, replace the part.
  6. E36 - tells that the protective sensor of the tubular heating element has broken. It is necessary to replace the device.
  7. E37 - indicates that the water level sensor 1 is not functioning. A replacement part will be required.
  8. E38 - warns that the pressure difference is not detected. The root cause of this may be clogging of the pipe. To eliminate the malfunction, it is necessary to clean the pipe or install a new pipe.
  9. E39 - indicates a defect in the sensor, which detects the overflow of liquid into the tank. Be sure to dismantle the old and install a working sensor.

When stating problems with various system sensors, it is necessary to identify which element is damaged, examine the wiring and, if necessary, completely replace the part.

Water heating codes

Very often, the AEG washing machine displays fault codes that indicate damage to the heating element or thermistor. Let us analyze the main notation for errors in this group.

  • E61 - informs the user that the heater cannot heat water to a predetermined temperature in the allotted time. It is important to diagnose the heater using a multimeter. A healthy heater will give a resistance value of 20-40 Ohms at room temperature.

This code will never appear during the normal operation of the AGR; it is possible to determine an error of this kind only during the service test.

  • E62 - indicates that for a given period of time (5 minutes) the water temperature has exceeded 88 ° C. In other words, the machine overheats. First, examine the thermistor - you can check it with a tester. When measuring the sensor resistance at room temperature, a value in the range from 5.7 to 6.3 kOhm should be displayed on the screen of the multimeter. If the thermistor is working, diagnose the heater and change the part if necessary.
  • E66 - warns that the TEN relay is out of order. It is necessary to double-check the operability of the relay, as well as its main circuit.
  • E68 - indicates a very large leakage current in the washer. To eliminate the malfunction, it is necessary to replace the tubular heater, and also check the elements directly related to it: a temperature measuring sensor and wiring.
  • E71 - tells that the thermostat's resistance is out of range. To find a way out of this situation, it is necessary to examine the thermistor for an open circuit or the fact of a short circuit in the thermostat. You should also inspect the heater, perhaps it was he who failed.
  • E74 - detects the offset of the NTC temperature sensor in the system. To reset the error code, just check its location in the tank and, if it is offset, set it in the right place.
  • E3A - designation tells about the breakdown of the heater relay. In such a situation, a relay replacement will be required.

When you see one of the described codes on the screen, you need to eliminate the problem as soon as possible. After all, problems with heating the water can lead to even more serious consequences.

Engine and Drive Issues

The engine is one of the important elements of the device of the washing machine. If errors appear on the screen that warn of any problems with the motor or drive mechanism, you must act immediately.

  1. E51 - tells that there was a short circuit in the triac of the engine. You can reset the code by checking the operation of the triac, and if a failure is detected, by replacing the non-functioning element.
  2. E52 - states that the controller has not received the necessary commands from the tachogenerator. Perhaps this was due to tearing the washer holding the coil from the surface of the tachogenerator. Correct the situation by changing the sensor.
  3. E53 - indicates a violation of the control circuit of the triac of the electric motor. To remove the code, diagnose all connection elements.
  4. E54 - signals “sticking” of the contact part of the motor reverse relay. Inspection and replacement of the relay will cope with the problem.
  5. E55 - states that an open circuit has occurred in the electric motor circuit. Checking the wiring and the engine itself will help to fix the error, and if necessary, replacing them.
  6. E56 - tells that the signals from the tachogenerator do not enter the system. You must replace the item.
  7. E57 - warns that the supplied current exceeded the permissible value of 15 A. One of three methods will help to cope with the problem: replacing the engine, repairing the wiring, changing the module.
  8. E58 - appears when the phase current of the SMA motor becomes more than 4.5 A. It is possible to remove the error if you reinstall the motor, repair the wiring, or replace the module.
  9. E59 - says that the tachogenerator does not give pulses for 3 seconds after changing the speed of rotation of the drum. Perhaps you should replace the engine, perform maintenance and repair of electrical wiring, change the tachogenerator to a new one, or even replace the control module.

The above-mentioned problems are quite difficult to diagnose and eliminate, especially when it comes to working with the control board. Therefore, before conducting diagnostics and repairs, we advise you to study this topic well, or to resort to the help of professional masters.

Filter and valve malfunctions

Let's move on to the next group of trouble codes programmed in the AEG washrooms. Errors will relate to the functioning of the valves and filter elements of the machine.

  • EC1 - detects the blocking of the water intake valve. To fix the malfunction, you will have to check the contacts, electronics or change the filling valve.
  • EF1 - informs that a clogged dust filter has been detected. You have to clean the drain system.
  • EF2 - appears with excessive foaming during discharge. Perhaps this situation is caused by “busting” the detergent or the presence of blockages in the hoses of the drain system. The solution will be to clean the elements, or the correct dosage of the powder.
  • EF4 - warns of incorrect operation of the flow sensor - it does not transmit a signal with functioning filling valves. The reason for this may be a shut-off valve on the water pipe or low pressure in the water supply system.

In most cases, fixing the problem with the filler valve and filters is easy. Therefore, you can cope with the failure that you have yourself, without the help of repairmen.

Failure of individual elements and modules

And finally, we will analyze the error codes that appear on the digital display due to the failure of individual parts and elements of the AEG brand washers. These include:

  • E41 - indicates a loose closing of the hatch door, it does not lock in position. Try to press the door with force, if this does not help - you will need to repair the hatch blocking device, the guide, or change the handle.
  • E42 - states a violation in the operation of the UBL. Inspect the hatch blocker, if a defect is detected, install a new device.
  • E43 - informs about damage to the main triac of the hatch of the hatch door. A change of part to a working one will be required.
  • E44 - Says that the sunroof closing sensor is broken. Replacing the old sensor with a new one can eliminate this error.
  • E45 - allows you to detect damage to the elements of the connection between the control triac and UBL. It is necessary to check all sections of the circuit.
  • E82 - indicates a failure when trying to select the washing mode with the selector knob. Such an error can be highlighted due to a failure of the control board, wire breakage, damage to the selector.
  • E83 - indicates that the data from the control knob for washing programs is not read by the intellect. You will have to replace the main module.
  • EF5 - appears when the washing mode is interrupted due to an imbalance in the drum. Solving this problem is very simple - you need to distribute things on the surface of the drum or reduce the amount of loaded laundry.

Depending on the model of the brand washing machine AEG error codes can be displayed using excellent alphanumeric combinations. So, for example, for some washers in the event of the failures already described above, somewhat different notations will be relevant:

  • C0 - indicates a failure of the pressure switch;
  • C1 - tells that the water does not enter the SMA tank;
  • C2 - states the fact of a defect in the hatch blocking device;
  • C3 - informs about damage to the main control module;
  • C4 - indicates a malfunction of the drainage pump;
  • C5 - signals about overheating of the motor sensor;
  • C6 - warns of a failure of the pressure switch;
  • C7 - indicates a malfunction of the tubular heater;
  • C8 - talks about a malfunction in the thermistor;
  • C9 - indicates that the TACHO sensor is faulty;
  • CF - indicates a failure in the memory of intelligence.

What to do when identifying a particular error? First, study as much information as possible on this issue. Secondly, to adequately assess their strength in resolving the issue. If there is a sufficiently complicated repair that requires special equipment, as well as in-depth knowledge and skills, it is better to resort to the help of specialists.
