Possible Causes
NTC sensor reading too hot or too cold, sensor not seated in tub, wiring short to heater, control board misreading sensor
How to Fix / Troubleshooting
Safety first: Unplug the unit and ensure no hot water is present in the drum before working.
Step-by-step checks:
- 1. Confirm actual water temperature: If the error appears immediately on a cold start, suspect sensor or wiring rather than real overheat.
- 2. Check sensor seating: Ensure the NTC is fully inserted into its well in the tub or heater housing. A loose sensor can read incorrectly.
- 3. Test resistance at different temps: Measure NTC resistance at room temperature and again after warming it slightly (e.g., in warm water in a plastic bag). Resistance should change smoothly. Replace if readings are erratic.
- 4. Inspect wiring for shorts: Look for melted insulation near the heater or tub. Repair any shorts and secure wiring away from hot surfaces.
