tE Thermal error
What this code means
A thermistor/temperature-sensing circuit fault — triggers if water exceeds the expected temperature or the sensor/heater circuit doesn't behave as expected. The root cause is often the thermistor sensor itself rather than the heating element.
Most likely causes
- Failing heating element
- Faulty temperature sensor
What to try first
Not user-serviceable beyond a power-cycle reset.
Safety note: if this code returns after one clean reset, stop resetting it — repeated lockouts usually mean a real fault that needs a licensed technician. Never bypass a safety switch.
