AEG washing machine error codes

SM AEG error codes Automatic washing machines from the renowned brand AEG boast excellent technical specifications, high build quality, and a wide range of features and extras. These washing machines are equipped with a self-diagnostic system for detecting potential malfunctions—a large number of different error codes are programmed into the machine's memory, allowing the user to immediately identify any malfunctions. Upon detecting a malfunction, the electronic unit immediately displays the error code on the digital display.

The self-diagnostic system database contains about a hundred different error codes, making it difficult to constantly remember what each one means. We'll provide you with a detailed explanation of all the codes to help you correctly diagnose the problem and perform repairs yourself.

Codes for water discharge and filling

What should you do if your washing machine suddenly stops working and reports a malfunction, displaying an unknown code on the screen? First, you need to determine which system component is faulty. First, let's look at errors related to filling the drum or draining waste liquid from the unit.

E11 – indicates that the automatic machine was unable to fill the tank with water to the required level within the specified period of time. The washing machine may display this symbol due to a defective inlet valve, damage to its winding, a clogged inlet hose, or a filter installed at the entrance to the system. You can fix the problem yourself by checking the valve with a multimeter (the working element will show a resistance of 3.75 kOhm), cleaning the water intake hose and filter.
E13 – indicates a water leak from the system. In most cases, the liquid leaks into the washing machine's tray. The unit should be inspected for any abnormal leaks.
E21 – informs the user that the washing machine has not drained the wastewater within the specified time. This failure could have several causes: a damaged pump, a clogged drain system, a faulty drain pump, or a defective control board. You can diagnose the drain pump with a multimeter; when checking the pump winding, the tester should show a reading of 170 ohms.
E23 – warns that a fault has been detected in the main triac located on the washing machine's control board. This error code can be reset by simply checking and replacing the triac or replacing the washing machine's control unit.
E24 – indicates a fault in the "control triac - drain pump" connection. To correct this, examine each section of the circuit and diagnose all components using a multimeter.
EF3 – indicates the "Aqua Control" function has been activated. Another cause is a broken or damaged pump wire. Either the pump or the pump cable will need to be replaced.

Once you understand the problem with the system, repairs will be easier. The search for the faulty component will quickly narrow down to one or two elements that need to be tested.

Electrical and electronic failure

When electronics malfunction, a specific group of codes may appear on the display. Problems can be caused by both problems with the main electrical system and damage to the circuit breaker wiring. Let's look at the symbols in this category.

E91 – indicates a communication problem between the control board and the washing machine's interface. The solution is to replace the main control unit.
E92 – indicates inconsistent operation of the user interface and the main control module.
E93 – indicates that the washing machine configuration is incorrect. Specifying the correct configuration code will help correct the inaccuracy.
E95 – indicates a fault in the “processor – non-volatile memory of the washing machine” circuit.
E96 – signals an incorrect configuration of external components (in particular the controller).
E97 – indicates that the wash mode selector knob is not functioning correctly with the control module. This may be due to a configuration error or a malfunction of the main unit.
E98 – indicates inconsistent operation between the unit's motor and the control unit. Either the circuit wiring needs to be replaced or the control board needs to be replaced with a working part.
E9A – indicates a software problem between the washing machine's electronics and the speaker. This code can only be cleared by replacing the main control module.
EH1 (EB1) – indicates that the mains voltage is above the acceptable limit. There may be interference in the electrical network, or the washing machine's power supply may be unreliable. If everything is normal, the control unit should be checked.
EH2, EH3 (EB2, EB3) – errors inform the user about excessively high and low voltage in the electrical network, respectively. In both cases, the electronics will need to be replaced.
EHE (EBE) – indicates damage to the protective circuit relay.
EHF (EBF) – signals that the protective circuit could not be recognized.

It's best to entrust repairs to a professional when it comes to electronics. The electronic module is the most expensive component of the washing machine, so it's best not to attempt repairs without specialized knowledge and skills.

Problems with sensors

Let's look at the AEG washing machine error codes that indicate problems with various sensors. The main symbols for this type of fault are listed below.

E31 – indicates a faulty water level (pressure) sensor in the tank. To correct this, inspect the pressure switch and the contacts leading to it. If a broken wire is detected, the connection must be repaired. If the sensor itself is faulty, the pressure switch must be replaced.
E32 – indicates that the pressure switch is not calibrated. For example, after the initial calibration, the liquid level in the tank is above the 0-66 mm mark, but the anti-boiling level has not been reached.
E33 – warns that three system sensors are not working in sync with each other. These include the pressure switch, the level 1 sensor, and the heating element protection system. Several factors could cause this failure, including damaged components or clogged pipes. E33 can also be displayed if the electrical system voltage is too high, causing the heating element to leak onto the washing machine housing. Check the tubular heater for a breakdown by setting the multimeter to buzzer mode and touching its probes to the surface of the element.
E34 – indicates that the connection between the pressure switch and the anti-boil level sensor is not working properly. If the symbol appears on the digital screen for more than 60 seconds, the sensor should be replaced, the circuit contacts should be examined, and if necessary, they should be replaced or cleaned. You can try changing the sensor pipe.
E35 – indicates that the tank is overfilled with water. To resolve this, check the water level sensor with a multimeter. If the pressure switch is defective, replace the part.
E36 – indicates that the heating element's protective sensor is faulty. The unit needs to be replaced.
E37 – indicates that water level sensor 1 is not functioning. The part will need to be replaced.
E38 – warns that the pressure difference is not being detected. This could be caused by a clogged hose. To fix the problem, clean the hose or install a new one.
E39 – indicates a defective sensor that detects fluid overflow into the tank. It is essential to remove the old sensor and install a working one.

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

Codes dedicated to water heating

AEG washing machines often display error codes indicating damage to the heating element or thermistor. Let's look at the main error codes for this group.

E61 – informs the user that the heating element is unable to heat the water to the set temperature within the allotted time. It is important to diagnose the heater using a multimeter. A working heating element will produce a resistance of 20-40 Ohms at room temperature.

This code will never appear during normal operation of the washing machine; an error of this kind can only be detected by performing a service test.

E62 – indicates that the water temperature has exceeded 88°C within a specified period of time (5 minutes). In other words, the machine is overheating. First, examine the thermistor; you can check it with a tester. When measuring the sensor's resistance at room temperature, the multimeter screen should display a value between 5.7 and 6.3 kOhm. If the thermistor is working properly, diagnose the heating element and replace it if necessary.
E66 – warns that the heating element relay has failed. The relay and its main circuit must be rechecked.
E68 – indicates a very large current leak in the washing machine. To fix the problem, replace the tubular heater and check the components directly connected to it, such as the temperature sensor and wiring.
E71 indicates that the thermostat resistance is outside the acceptable range. To resolve this issue, inspect the thermistor for an open circuit or short circuit. The heating element may also be faulty.
E74 – indicates that the NTC temperature sensor in the system has become misaligned. To reset the error code, simply check its position in the tank and, if misaligned, reinstall it.
E3A – this code indicates a faulty heating element relay. In this case, the relay will need to be replaced.

If you see one of the codes described on the screen, it's essential to address the problem as soon as possible. Water heating problems can lead to even more serious consequences.

Problems with the engine and drive mechanism

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

E51 – indicates a short circuit in the engine's triac. The code can be reset by checking the triac's functionality and, if a fault is detected, by replacing the faulty component.
E52 – indicates that the control unit is not receiving the required commands from the tachogenerator. This may be due to the washer holding the coil being torn off the tachogenerator surface. This can be corrected by replacing the sensor.
E53 – indicates a malfunction in the electric motor's triac control circuit. To clear the code, diagnose all connected components.
E54 – indicates a stuck contact on the electric motor reverse relay. Inspecting and replacing the relay will resolve the issue.
E55 indicates a break in the electric motor circuit. Checking the wiring and the motor itself, and replacing them if necessary, will help fix the error.
E56 – indicates that signals from the tachogenerator are not being received by the system. The element needs to be replaced.
E57 – warns that the supplied current has exceeded the permissible value of 15 A. One of three methods will help solve the problem: replacing the motor, repairing the wiring, or replacing the module.
E58 – appears when the washing machine's motor phase current exceeds 4.5 A. The error can be cleared by reinstalling the motor, repairing the wiring, or replacing the module.
E59 – indicates that the tachogenerator doesn't generate pulses within 3 seconds of changing the drum rotation speed. It may be necessary to replace the motor, service and repair the electrical wiring, replace the tachogenerator with a new one, or even replace the control module.

The above-mentioned problems are quite difficult to diagnose and fix, especially when it comes to working on the control board. Therefore, before attempting diagnostics and repairs, we recommend thoroughly researching the topic or seeking professional help.

Malfunctions of filters and valves

Let's move on to the next group of error codes programmed into AEG washing machines. These errors will concern the operation of the machine's valves and filter elements.

EC1 – indicates a blocked water inlet valve. To resolve the issue, you'll need to check the contacts, electronics, or replace the inlet valve.
EF1 – indicates that the waste filter is clogged. The drainage system needs to be cleaned.
EF2 – Occurs when excessive foaming occurs during draining. This may be caused by too much detergent or clogged drain hoses. Cleaning the elements or adjusting the detergent dosage correctly will resolve the issue.
EF4 – warns of incorrect operation of the flow sensor – it does not transmit a signal when the fill valves are functioning. This could be caused by a closed valve on the water pipe or low pressure in the water supply system.

In most cases, troubleshooting problems with the inlet valve and filters is straightforward. Therefore, you can resolve the issue yourself without resorting to repair services.

Failure of individual elements and modules

Finally, let's look at the error codes that appear on the digital display due to failure of individual parts and components of AEG washing machines. These include:

E41 – Indicates the hatch door isn't closing properly and won't lock in place. Try pushing the door firmly; if that doesn't help, the hatch locking mechanism, guide, or handle will need to be repaired.
E42 – indicates a malfunction in the hatch locking system. Inspect the hatch locking system; if a defect is detected, install a new one.
E43 – indicates damage to the main triac of the sunroof lock. The part will need to be replaced with a working one.
E44 – indicates that the sunroof sensor is broken. Replacing the old sensor with a new one will fix this error.
E45 – allows you to identify damage to the connection elements between the control triac and the door lock. All sections of the circuit must be checked.
E82 – indicates an error when attempting to select a wash cycle using the selector knob. This error may be caused by a faulty control board, broken wiring, or a damaged selector knob.
E83 – indicates that the data from the washing program selector knob is not being read by the intelligent system. The main module will need to be replaced.
EF5 – Occurs when the wash cycle is interrupted due to an imbalance in the drum. This problem can be easily resolved by redistributing the laundry across the drum or reducing the load volume.

Depending on the model of the washing machine brand AEG error codes can be displayed using different alphanumeric combinations. For example, for some washing machines, when the above-described failures occur, slightly different symbols will be relevant:

C0 – indicates failure of the pressure switch;
C1 – indicates that water is not entering the washing machine tank;
C2 – confirms the fact of a defect in the hatch locking device;
C3 – informs about damage to the main control module;
C4 – indicates a malfunction of the drainage pump;
C5 – signals overheating of the electric motor sensor;
C6 – warns of failure of the pressure relay;
C7 – indicates incorrect operation of the tubular heater;
C8 – indicates a malfunction in the thermistor;
C9 – indicates that the TACHO sensor is faulty;
CF – signals a failure in the intellect’s memory.
