Possible Causes
Open or shorted NTC sensor, Loose NTC connector, Damaged wiring harness to heater sensor, Moisture ingress into sensor housing
How to Fix / Troubleshooting
Safety first: Unplug the washer and allow it to cool before working near the heater or tub.
- Locate the NTC sensor: On many Little Swan models, the NTC is mounted in the heater bracket at the bottom of the tub. Remove the rear panel to access it.
- Check connector: Ensure the NTC plug is firmly attached and free of corrosion or detergent residue. Clean and reseat if necessary.
- Measure resistance: Disconnect the NTC and measure its resistance at room temperature. Compare to the service manual chart. A reading near 0 Ω (short) or infinite (open) indicates a bad sensor.
- Replace NTC sensor: If faulty, remove the old sensor from its bracket or grommet and install a compatible Little Swan NTC, ensuring a snug, watertight fit.
