Neff Overheating / Temperature Regulation Issue

Washer door glass becomes extremely hot during high-temperature washes.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty NTC sensor, Stuck heater relay, Incorrect program selection, Control module fault

Safety: Avoid touching the door glass during hot cycles. Unplug the washer before internal checks.

Verify program: Ensure you are not using a boil wash (90–95 °C) unintentionally.
Check NTC sensor: Test and replace the NTC as described for E11 if it is not reading correctly.
Heater relay: If the heater remains on continuously, the relay on the control board may be stuck closed, requiring board replacement.
Monitor behavior: After repairs, run a 40 °C cycle and confirm that the door becomes only mildly warm.
