Possible Causes
Stuck heater relay on control board, Faulty NTC sensor giving incorrect readings, Limescale buildup on heater causing localized overheating, Poor water circulation over heater
How to Fix / Troubleshooting
Safety first: Disconnect power and allow the dishwasher to cool completely.
- Clean filters and spray arms: Ensure good water circulation by cleaning filters and spray arms so water flows properly over the heater.
- Inspect NTC sensor: Check the NTC wiring and connector. Replace the sensor if resistance readings are incorrect.
- Descale heater: If accessible, inspect the heater for heavy limescale. Descale or replace if heavily coated.
- Control board: If overheating persists, the heater relay on the control board may be stuck closed and the board should be replaced by a professional.
