Possible Causes
Shorted NTC temperature sensor, Limescale build-up affecting sensor reading, Stuck heater relay on AEG main PCB
How to Fix / Troubleshooting
Safety first: Turn off power and allow the dishwasher to cool completely before inspection.
- Visual inspection: Access the NTC sensor (usually mounted in the sump or heater assembly). Check for heavy limescale or contamination.
- Clean sensor area: Descale the sump and sensor area using a dishwasher cleaner or a dedicated descaling product according to instructions.
- Test sensor (advanced): Measure the NTC resistance at room temperature and compare with AEG specifications. Replace if out of range or shorted.
- Control board check: If the sensor is good but overheating persists, the heater relay on the PCB may be stuck closed and the board should be replaced by a professional.
