Possible Causes
Open or shorted NTC sensor, Disconnected NTC plug, Damaged wiring harness, Faulty PCB input circuit
How to Fix / Troubleshooting
Safety: Disconnect mains power before accessing the heater/NTC area.
- Locate NTC: Find the NTC sensor in the wash heater housing or on the tub wall.
- Check connection: Ensure the NTC connector is firmly plugged in and free of corrosion.
- Measure resistance: Use a multimeter to check NTC resistance. An open circuit or near-zero reading indicates failure; replace the AEG NTC sensor.
- Inspect harness: Follow the wires back to the PCB and repair any breaks or damaged insulation.
If a new sensor and good wiring do not clear E70, the control board may be defective.
