AEG Washing Machine Error Codes - Meanings and Solutions

AEG washing machines share their diagnostic system with sister brands Electrolux and Zanussi, using a similar E-number code structure. Understanding AEG washing machine error codes helps you resolve common issues with confidence.

Why AEG Washing Machine Error Codes Matter

AEG, Electrolux, and Zanussi are all part of the same corporate group and share manufacturing platforms, meaning most fault codes and their meanings carry over consistently between the three brands.

Common AEG Washing Machine Error Codes

E10 – Water Supply Error. The washer isn't filling correctly, often due to a faulty aquastop inlet hose. Solution: Inspect and replace the aquastop hose if it has triggered a safety shut-off.

E11 – Water Supply Error (Valve). A fault with the solenoid inlet valve. Solution: Check and, if necessary, replace the solenoid valve.

C2 – Drain Pump Error. The washer is struggling to drain. Solution: Clean the drain pump filter thoroughly; replace the pump if the fault continues.

C9 – Imbalance Detected. Excessive vibration has been detected during spin. Solution: On models with carbon-brush motors, worn brushes are a common cause and can be replaced.

E21 – Drain Error. The washer cannot properly drain the tub. Solution: Check the drain hose and pump filter for blockages.

E23 – Drain Pump Triac Fault. An electrical fault in the pump's control circuit. Solution: Professional testing of the control triac is required.

E40 – Door Fault. The door is open or not detected as securely closed. Solution: Check that the door is fully shut and the interlock is engaging properly.

E72 / E73 / E74 – Water Temperature Fault. The NTC sensor is detecting incorrect water temperature. Solution: Professional replacement of the NTC sensor is typically required.

E85 – Circulation Pump Error. A fault in the circulation pump. Solution: Professional replacement of the pump is usually needed.

E90 – Electronics Error. A general fault in the control module. Solution: Professional diagnosis of the control module and internal wiring is required.

When to Call a Professional

Water supply (E10, E11) and drain (C2, E21) faults are usually manageable with basic cleaning and inspection. Door (E40), temperature sensor (E72-E74), and electronics faults (E90) generally call for a qualified technician, since AEG's internal control systems need specialized diagnostic tools to service safely.
