Possible Causes
Open or shorted NTC sensor, Damaged NTC wiring harness, Poor connection at heater/NTC block, Control module sensor input fault
How to Fix / Troubleshooting
Safety: Unplug the washer. Heating components can be hot after a cycle; allow to cool.
- Locate NTC sensor: The NTC is usually clipped into the heater housing or inserted into a pocket in the tub near the heater.
- Check connector: Disconnect the NTC plug and inspect for corrosion or loose pins. Clean and reseat the connector.
- Measure resistance: Use a multimeter to measure NTC resistance at room temperature. Compare with the specification for your Neff model (commonly several kΩ). A reading of 0 Ω (short) or infinite (open) indicates a failed sensor.
- Replace NTC: Release the retaining clip or pull the sensor from its pocket. Fit the new sensor, ensuring good contact with the tub or heater body, and reconnect the wiring.
- Test a warm wash: Run a 40 °C program and check that the machine heats and completes without E11.
