Possible Causes
Open or shorted NTC sensor, Loose NTC connector, Damaged wiring harness to NTC, Faulty control board input circuit
How to Fix / Troubleshooting
Safety first: Unplug the washer and allow it to cool.
Step-by-step checks:
- Locate the NTC: Usually clipped into the heater bracket or directly into the tub wall near the heater.
- Inspect and reseat connector: Ensure the NTC plug is firmly connected and free of corrosion.
- Test NTC resistance: With a multimeter, measure resistance at room temperature and compare with service data. A reading near 0 Ω (short) or infinite (open) indicates failure.
- Replace NTC if faulty: Release the clip or grommet, remove the sensor, and fit a new Rosières-compatible NTC, ensuring a watertight seal.
