AEG Washing Machine Error Codes
AEG Lavamat washing machines display error codes as E followed by two digits — E10, E20, E40, E50, E60, E90 and so on. The tens digit identifies the fault category: E1x is a fill fault, E2x is a drain fault, E4x is a door lock fault, E5x is a motor fault, E6x is a heating fault, E7x is an NTC sensor fault, and E9x is a control board or communication fault. AEG shares its manufacturing platform with Zanussi and Electrolux — the error code system is identical across all three brands.
AEG Lavamat washing machines: the error code system explained
AEG is owned by Electrolux AB and its Lavamat washing machine range is produced on the same manufacturing platform as Zanussi and Electrolux branded machines. This shared platform means the error code system is identical across all three brands — an E52 on an AEG Lavamat means exactly the same fault as an E52 on a Zanussi ZWF, and the diagnosis steps and replacement parts are the same.
This guide covers all AEG Lavamat error codes in full. The code structure uses a logical grouping system where the first digit after E identifies the fault system, making it straightforward to narrow down the general area of a fault before looking up the specific sub-code.
| Code group | System affected | Example codes |
|---|---|---|
| E1x | Water fill system | E10, E11, E12, E13 |
| E2x | Drain system | E20, E21, E22, E23, E24 |
| E3x | Pressure switch and water level system | E33, E34, E35, E36, E37, E39 |
| E4x | Door lock system | E40, E41, E42, E43, E44, E45 |
| E5x | Motor system | E50, E51, E52, E53, E54 |
| E6x | Heating system | E60, E61, E62, E63, E64, E65, E66, E67, E68 |
| E7x | NTC temperature sensor | E70, E71 |
| E9x | Control board and communication | E90, E91, E92, E93, E94 |
AEG Lavamat, Zanussi, and Electrolux washing machines are produced by Electrolux AB on shared manufacturing platforms with the same control systems. The E code error system in this guide applies equally to Zanussi and Electrolux branded washing machines. If you have a Zanussi or Electrolux machine displaying one of these codes, the diagnosis steps and replacement parts are identical to those described here for AEG.
E1x codes: water fill faults
Any AEG Lavamat code beginning with E1 relates to a problem with water entering the machine. These are among the most common error codes and the majority are resolved without replacing any components.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E10 | Water fill fault — machine not filling or fill taking too long | Tap closed or partially closed. Kinked or trapped inlet hose. Blocked inlet hose filter mesh. Low mains water pressure. Failed inlet valve solenoid. Aquastop hose triggered or blocked. | Confirm the tap is fully open. Straighten the inlet hose. Unscrew the inlet hose from the back of the machine and clean the small mesh filter inside the inlet port. Check household water pressure is adequate. |
| E11 | Slow or incomplete fill — fill taking longer than expected | Partially blocked inlet filter reducing flow rate. Mains water pressure borderline low. Inlet valve solenoid partially failing and not opening fully. | Same checks as E10. Clean inlet filter thoroughly. If pressure and filter are both acceptable, the inlet valve is the likely cause. |
| E12 | Water level sensor not confirming fill has completed | Blocked or kinked pressure switch hose preventing the pressure switch from reading the water level. Failed pressure switch. Soap suds blocking the pressure chamber. | Check and clear the pressure switch hose — a narrow pipe running from the drum to the pressure switch. Run a service wash on a hot cycle to clear soap residue from the pressure system. |
| E13 | Anti-flood device triggered — water detected in the machine base | Water has entered the base tray triggering the float switch. Possible sources include a failed door seal, leaking pump, cracked internal hose, or inlet valve fault. | Tilt the machine backward to drain the base tray, then return to upright. Investigate the leak source before using the machine again. Do not use it until the leak has been found and resolved. |
E2x codes: drain faults
Any AEG Lavamat code beginning with E2 relates to a problem with water leaving the machine. E20 is one of the most commonly seen AEG error codes and in the vast majority of cases the cause is a blocked pump filter rather than a failed pump.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E20 | Drain fault — machine unable to drain within expected time | Blocked pump filter. Kinked or obstructed drain hose. Standpipe too high. Foreign object blocking the pump impeller. Failed drain pump motor. | Clean the pump filter — behind the small access panel at the bottom front of the machine. Place towels and a shallow tray in front before opening as water will flow out. Unscrew the filter anticlockwise, remove all debris, check the pump cavity for foreign objects, and refit firmly. See our full guide: washing machine not draining. |
| E21 | Slow drain — machine draining but taking longer than expected | Partially blocked pump filter. Partial blockage in drain hose. Pump impeller sluggish but not failed. | Clean the pump filter thoroughly. Check the drain hose for partial kinks or restrictions. |
| E22 | Drain pump monitoring fault — pump running but flow not confirmed as expected | Partially blocked pump. Pressure switch hose issue causing incorrect water level reading during drain. Pump capacitor beginning to fail. | Clean pump filter. Check pressure switch hose. If the machine appears to drain but the code persists, the pump or pressure switch requires testing. |
| E23 | Drain pump motor failure | Failed drain pump motor. Failed pump capacitor. Wiring fault to pump. | Test the drain pump for continuity with a multimeter — open circuit confirms motor failure. Genuine AEG/Electrolux pump replacements are available through our spare parts section. |
| E24 | Drain pump relay fault — board relay controlling the pump has failed | Failed relay on the main PCB. Board-level fault. | If E23 component tests are clear, the fault is in the pump relay on the control board. Engineer diagnosis recommended before committing to board replacement. |
E3x codes: pressure switch and water level faults
Codes in the E3x range relate to the pressure switch system that monitors water level inside the drum. Some E30 and E31 codes on certain AEG Lavamat models also relate to door lock faults — refer to your model’s documentation if in doubt.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E30 / E31 / E32 | Pressure switch fault or door lock fault (model dependent) | On most models: pressure switch fault or blocked pressure hose. On some models: door lock fault. | Check the pressure switch hose for blockage or kinks. Run a service wash. If a door fault is suspected, confirm the door closes correctly and test the interlock. |
| E33 | Incongruency between pressure switch readings — the two water level monitoring systems are not in agreement | Hydraulic circuit blockage. Failed electronic pressure switch. Failed secondary pressure switch. Wiring fault. Main PCB fault. | Check the pressure switch hose is clear and connected at both ends. Test the pressure switch. This code may require engineer diagnosis to pinpoint the specific cause. |
| E34 | Incongruency between pressure switch and secondary water level sensor | Disagreement between two water level monitoring components. Pressure switch fault, secondary sensor fault, wiring or PCB fault. | Check pressure hose and connections. Engineer diagnosis required to test individual components. |
| E35 | Water level too high — overfilling detected | Inlet valve not closing fully. Failed pressure switch reading level incorrectly. Pressure switch hose blocked causing false high reading. | Check whether water is visibly above the door seal. If overfilling is confirmed, the inlet valve is the likely cause. If level appears normal, test the pressure switch. |
| E36 / E37 | Pressure switch sensing circuit fault | Failed pressure switch or secondary switch. Wiring fault. Blocked pressure hose. | Check pressure hose. Test pressure switch. Engineer diagnosis if checks are clear. |
| E39 | Anti-flood device or high-voltage pressure switch fault | Anti-flood float triggered. HV pressure switch fault. Internal leak. | Check for water in the machine base. Tilt machine to drain if necessary. Investigate leak source. |
E4x codes: door lock faults
Any code beginning with E4 relates to the door lock system. E41 is the most commonly encountered AEG door fault code and is frequently caused by a failed door interlock after the machine has been in service for several years.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E40 | Door lock fault — general group code | See E41 to E45 for the specific cause. | Open and firmly close the door, ensuring nothing is caught in the seal. If the code persists, check the sub-code. |
| E41 | Door open — machine not detecting the door is closed | Door not fully latched. Obstruction in door seal. Failed door interlock not registering as closed. Broken door handle or catch. | Open and firmly close the door. Check for clothing trapped in the seal. If the door closes correctly and E41 persists, the door interlock has likely failed. Replacement interlocks for AEG Lavamat machines are available through our spare parts section. See our guide: washing machine door won’t open. |
| E42 | Door lock mechanism fault — mechanical locking failure | Failed door interlock mechanical component. Door catch worn. Door handle linkage broken. | Test the door interlock for continuity. Replacement on AEG Lavamat machines is a practical DIY repair with the correct part. |
| E43 | Door lock control circuit fault | Wiring fault between door interlock and control board. Faulty control board door lock circuit. | Check wiring to the door interlock. If wiring is intact, engineer diagnosis required for board circuit fault. |
| E44 | Door open signal not received by control board | The interlock is physically locked but the board is not receiving the confirmation signal. Wiring fault. Failed interlock signal circuit. | Test the interlock’s electrical signal output. Check wiring connectors at both interlock and board. |
| E45 | Door lock relay fault — relay on PCB controlling door locking | Failed relay on main PCB controlling the door lock mechanism. | Engineer diagnosis required for board relay fault. |
E5x codes: motor faults
Any code beginning with E5 relates to the motor system. E52 is the most commonly encountered AEG motor fault code and in the majority of cases on machines over five years old, the cause is worn motor carbon brushes. This is one of the most cost-effective washing machine repairs available.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E50 | Motor fault — general group code | See E51 to E54 for specific cause. On older machines without sub-code display, E50 most commonly indicates worn carbon brushes. | Check whether the drum rotates freely by hand with the machine unplugged. If it does, inspect the motor carbon brushes. |
| E51 | Motor power triac short circuit — triac on PCB has failed | The triac component on the main control board that controls motor power has short-circuited. May also cause the machine to trip the RCD. | If E51 appears and the machine trips the electrics, the triac is the likely cause. Engineer diagnosis before committing to board replacement. |
| E52 | No motor movement detected — tachogenerator or motor fault | Worn motor carbon brushes (most common cause on machines over five years old). Failed tachogenerator. Wiring fault to tachogenerator. Motor winding failure. Foreign object jamming the drum. | Check carbon brushes — replace if worn below 10mm. Test tachogenerator resistance (typically 100 to 200 ohms — open circuit confirms failure). Check drum rotates freely with machine unplugged. See our dedicated guide: E50/E52 motor fault guide (AEG and Zanussi use identical components). |
| E53 | Motor triac sensing circuit fault — PCB sensing circuit failed | Fault in the triac sensing circuit on the main PCB. | Engineer diagnosis required — PCB sensing circuit faults are not DIY repairable. |
| E54 | Motor relay faulty — relay on control board controlling motor power | Failed motor relay on the main PCB. | Engineer diagnosis required. Test the motor directly first to confirm it is functioning before concluding the relay has failed. |
E6x codes: heating faults
Any code beginning with E6 relates to the heating system. E61 (insufficient heating) is the most commonly encountered E6x code on AEG Lavamat machines and is frequently caused by a failed heating element or NTC thermistor, or by heavy limescale in hard water areas.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E60 | Heating fault — general group code | See E61 to E68 for the specific cause. | Confirm the machine is actually failing to heat by checking the water temperature at the end of a hot wash. |
| E61 | Insufficient heating — water not reaching target temperature within expected time | Failed heating element (open circuit). Failed NTC thermistor giving incorrect temperature reading. Wiring fault between element or thermistor and control board. Limescale heavily fouling the element in hard water areas. | Test the heating element for continuity with a multimeter — open circuit confirms failure. Test the NTC thermistor (approximately 30,000 ohms at room temperature, falling with temperature). In hard water areas, run a descaling cycle before testing components. |
| E62 | Overheating detected — water temperature exceeding expected level | NTC thermistor reading incorrectly low, causing the board to keep the element running. Heating element relay stuck in the closed position. Control board fault. | Test the NTC thermistor. If it reads correctly, the fault is in the relay or control board. |
| E63 | Safety thermostat triggered | The safety thermostat has cut out due to excessive temperature. Can be caused by a failing NTC thermistor, a blocked/scaled element, or a relay stuck closed. | Allow the machine to cool fully. Investigate why the safety thermostat operated before restarting. |
| E64 | Heating element contact fault | Loose or corroded connection at heating element terminals. Element partially failed with intermittent contact. | Check element terminals and wiring connectors. Refit any loose connections. Test element resistance. |
| E65 | Anti-flood device triggered during heating phase | Water in the machine base triggering the anti-flood system during a heat cycle. | Same checks as E13 — tilt machine to drain base tray, investigate leak source. |
| E66 | Heating element relay contacts always closed — relay stuck on | Failed relay on the control board with contacts stuck closed, causing the element to remain active continuously. | Engineer diagnosis required. Relay or board replacement depending on the board design. |
| E67 | Power supply fault affecting the heating circuit | Voltage irregularity reaching the heating circuit. Poor supply from wall socket or mains. | Check the machine is connected directly to a wall socket without an extension lead. Test the socket with another appliance. |
| E68 | Heating relay fault or communication fault in heating circuit | Relay fault on board. Communication error between heating circuit monitoring and main control logic. | Engineer diagnosis required. |
E7x codes: NTC temperature sensor faults
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E70 / E71 | NTC temperature sensor fault — sensor giving incorrect or no reading | Failed NTC thermistor. Loose or corroded wiring connector. Limescale on thermistor in hard water areas. Control board fault generating false reading. | Test the NTC thermistor with a multimeter — approximately 30,000 ohms at room temperature, falling as temperature rises. Open circuit confirms failure. Check wiring connectors. Descale if in a hard water area before replacing. |
E9x codes: control board and communication faults
Codes in the E9x range indicate communication or configuration problems within the electronic control system. A power reset resolves some transient E9x codes — always try this first.
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| E90 | Communication fault between control panel and main PCB | Wiring harness fault between user interface and main board. Moisture on board connections. Board failure. | Switch the machine off at the mains for 60 seconds and restart. If E90 returns consistently, check for visible moisture on the board connections. Engineer diagnosis required if persistent. |
| E91 | Communication error — internal control board fault | Internal communication error within the main control board. Wiring harness fault. | Power cycle the machine. If the code persists, engineer diagnosis required. |
| E92 | Communication error — secondary module failure | Communication breakdown between main board and secondary control module. Wiring fault. | Power cycle. Check wiring harness connectors. Engineer diagnosis if persistent. |
| E93 | Configuration fault — machine incorrectly configured or configuration data lost | Control board has lost or has incorrect configuration data. Can occur after a power surge or following board repair with an incorrectly configured module. | Power cycle. If the code persists, the board requires reconfiguration by an engineer with access to the correct configuration data for your specific model. |
| E94 | Incorrect cycle configuration — control board data fault | Board cycle configuration data is incorrect or corrupted. | Power cycle. Engineer diagnosis required if persistent. |
EF0: anti-flood and overflow code
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| EF0 | Anti-flood, overflow, or over-foaming detected | Water leakage into the machine base triggering the anti-flood float switch. Excessive foam from too much or wrong detergent. Unbalanced load sensor on some models. | Check through the door glass for excessive foam. If foam is present, run an empty rinse-and-spin cycle to clear it and reduce detergent on future washes. If no foam is visible, check for water in the machine base by tilting the machine backward. Identify the leak source before using the machine again. |
What to check before calling an engineer
-
Power cycle the machine. Switch off at the wall socket, wait 60 seconds, and switch back on. Transient error codes caused by voltage fluctuations, software events, or momentary sensor readings are common and often clear after a power reset. If the same code does not return consistently, monitor the machine over the next few cycles before taking action.
-
Clean the pump filter (E20, E21, E22, E23 drain codes). This is the single most productive check for any drain-related code and resolves the majority of E20 faults on AEG Lavamat machines. The filter is behind the small access panel at the bottom front of the machine. Place towels and a shallow tray in front before opening. Unscrew anticlockwise, remove all debris including coins and small items, check the pump cavity, and refit firmly.
-
Check the water supply (E10, E11 fill codes). Confirm the tap is fully open. Straighten the inlet hose. Unscrew the inlet hose from the back of the machine and clean the small mesh filter inside the inlet port.
-
Check the door closes correctly (E40, E41 door codes). Open and firmly close the door, confirming no clothing is caught in the seal. If the door closes correctly and the code persists, the door interlock has likely failed.
-
Inspect motor carbon brushes (E50, E52 motor codes). With the machine unplugged, check the drum rotates freely by hand. If it does, inspect the motor carbon brushes — replace if worn below 10mm. Carbon brush replacement is one of the most cost-effective washing machine repairs available and resolves the majority of E52 motor fault codes on older AEG Lavamat machines.
-
Descale the machine (E61, E70, E71 heating and NTC codes in hard water areas). Limescale on the element and NTC thermistor causes temperature faults. Run an empty cycle on the hottest programme with a proprietary descaler before testing or replacing components.
-
Check the pressure switch hose (E12, E33, E35 pressure codes). The pressure switch hose is a narrow pipe running from the drum to the pressure switch. Check it is not kinked, blocked, or detached at either end. Run a service wash to flush soap residue from the pressure system.
Always switch the machine off at the wall socket and unplug it before accessing the pump filter, opening any panels, or inspecting internal components. Never work on electrical components with the machine connected to the mains. For guidance on safe DIY appliance repair, see our DIY appliance repair safety guide.
Can I fix an AEG Lavamat error code myself?
Straightforward to check or fix yourself
Cleaning the pump filter (E20, E21, E22, E23 drain codes). Checking and cleaning the inlet hose filter (E10, E11 fill codes). Checking the door closes correctly (E40, E41 door codes). Power cycling to clear transient codes. Descaling for temperature codes in hard water areas. Replacing motor carbon brushes (E50, E52 motor codes). Replacing the door interlock on confirmed interlock failure. Replacing the NTC thermistor on confirmed thermistor failure (E70, E71, E61).
Requires an engineer or advanced competence
Motor triac fault (E51). Motor triac sensing circuit (E53). Motor relay fault (E54). Control board faults (E9x). Anti-flood investigation and leak source repair (E13, E39, EF0). Pressure switch incongruency (E33, E34). Heating relay or triac faults (E66, E68). Any fault that persists after all basic checks have been completed.
The platform note: AEG, Zanussi, and Electrolux
AEG Lavamat, Zanussi, and Electrolux washing machines are manufactured by Electrolux AB on shared platforms with identical control systems, components, and error code structures. This has three practical implications.
First, all the diagnosis steps in this guide apply equally to equivalent Zanussi and Electrolux washing machines. An E52 on a Zanussi ZWF is diagnosed and repaired in exactly the same way as an E52 on an AEG Lavamat — the machines are the same internally. Second, spare parts are frequently interchangeable across the three brands. Heating elements, NTC thermistors, door interlocks, drain pumps, and carbon brush sets listed for Zanussi models often fit equivalent AEG Lavamat machines. Third, if you have an AEG code that is not fully explained here, you can usefully cross-reference our full Zanussi error code guide, which covers every code in the same system in detail: Zanussi washing machine error codes.
AEG error code pointing to a fault you cannot resolve?
If basic checks have not resolved the fault and the code is pointing to a component failure, a qualified engineer is the right next step. We cover AEG Lavamat repairs nationwide with genuine Electrolux Group spare parts available for most models.
Frequently asked questions about AEG Lavamat washing machine error codes
What does E20 mean on an AEG Lavamat washing machine?
E20 is a drain fault code — the machine has been unable to drain water within the expected time. In the majority of cases this is caused by a blocked pump filter rather than a failed pump. The filter is behind a small access panel at the bottom front of the machine. Cleaning it takes around five minutes and resolves most E20 faults without any parts or engineer visit. If the filter is clear and E20 persists, check the drain hose for kinks and confirm the standpipe height, then test the drain pump motor.
What does E52 mean on an AEG Lavamat washing machine?
E52 indicates that no motor movement has been detected — the machine’s motor speed sensor (tachogenerator) is not reading drum rotation. The most common cause by a significant margin on machines over five years old is worn motor carbon brushes. With the machine unplugged, check that the drum rotates freely by hand. If it does, inspect the carbon brushes and replace them if worn below 10mm. If brushes are in good condition, test the tachogenerator resistance — typically 100 to 200 ohms, with an open circuit reading confirming failure.
What does E10 mean on an AEG Lavamat washing machine?
E10 is a water fill fault — the machine has not filled within the expected time. Check that the tap is fully open, the inlet hose is not kinked, and the small filter mesh inside the inlet port at the back of the machine is clean. If the water supply is correct and E10 persists, the inlet valve solenoid has likely failed and requires replacement.
What does E41 mean on an AEG Lavamat washing machine?
E41 indicates the door is not detected as closed. First confirm the door closes fully with nothing obstructing the seal. If it closes correctly and E41 persists, the door interlock has likely failed. Door interlock replacement is a common AEG Lavamat repair — genuine Electrolux Group replacement interlocks are available for most models and the repair is practical for a confident DIY repairer following proper safety procedures.
What does E61 mean on an AEG Lavamat washing machine?
E61 indicates insufficient heating during the wash cycle — the water has not reached the target temperature within the expected time. The most common causes are a failed heating element, a failed NTC thermistor, or heavy limescale on the element in hard water areas. Test the element for continuity with a multimeter — open circuit confirms failure. Test the NTC thermistor — approximately 30,000 ohms at room temperature. In hard water areas, run a descaling cycle before testing components.
Do AEG error codes apply to Zanussi and Electrolux machines?
Yes. AEG, Zanussi, and Electrolux are all owned by Electrolux AB and share the same manufacturing platforms and E code error system. An E52 on an AEG Lavamat is the same fault as an E52 on a Zanussi — the diagnosis steps and replacement parts are identical. Our full Zanussi washing machine error codes guide covers every code in the system in detail and applies equally to AEG Lavamat machines.
What does E90 mean on an AEG Lavamat washing machine?
E90 indicates a communication fault between the control panel and the main PCB. Switch the machine off at the wall for 60 seconds and restart — transient communication errors often clear on power reset. If E90 returns consistently, check for visible moisture or corrosion on the control board and wiring connectors. A persistent E90 typically requires an engineer to diagnose whether the issue is in the wiring harness or the board itself.
