Possible Causes
Defective water level sensor in steam generator, blocked level tube, wiring fault to level sensor, control board misinterpretation
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the oven to cool.
- Inspect level sensor: Locate the water level sensor on or near the steam generator. It may be a float switch or conductivity probe. Clean any scale or residue.
- Clear level tube: If a small tube connects the boiler to the sensor, ensure it is not blocked with limescale. Carefully flush with descaling solution if necessary.
- Check wiring: Verify that the sensor wiring harness is intact and firmly connected to the control board.
- Replace sensor: If the sensor does not change state when water level changes (test per service manual), replace it with the correct AEG part.
Warning: Do not bypass level sensors; this can cause dangerous overfilling or dry-boil conditions.
