How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the sump or heater area.
Steps:
- Locate NTC: The NTC temperature sensor is typically clipped into the sump or heater housing with two wires leading to the control board.
- Inspect connection: Check that the connector is firmly seated and free of corrosion or moisture.
- Measure resistance: With a multimeter, measure the NTC resistance at room temperature. Compare to service data if available; a reading of near 0 Ω (short) or infinite (open) indicates a faulty sensor.
- Replace if faulty: Release the clip, remove the old NTC, install the new sensor, and reconnect wiring.
When to call a technician: If the NTC tests good but E10 persists, the control board may be defective and should be checked by a professional.
