Safety First: Unplug the washer and allow it to cool if recently used.

Check NTC sensor: Test and replace the temperature sensor if out of spec.
Inspect heater relay: If the heater remains energized when it should be off (requires professional testing), the main control board must be replaced.
Verify water circulation: Ensure there are no severe blockages in the tub that would cause localized overheating around the heater.
