What the F1 Fault Code Means
The F1 fault code indicates a short circuit in the NTC temperature sensor circuit — the component responsible for monitoring the water temperature during a wash cycle. When this sensor circuit fails, the machine cannot safely regulate heating and will stop the programme.
Common Reasons This Fault Appears
Faulty NTC temperature sensor
The NTC sensor itself may have short-circuited, which is the most common cause of this fault. Water ingress or heat damage can cause the sensor to fail.
Damaged wiring to the sensor
A short circuit can also occur in the wiring connecting the NTC sensor to the control board rather than in the sensor itself.
Heating element fault
In some cases a fault with the heating element or its associated wiring can contribute to a short circuit in the temperature sensor circuit.
Safe Checks You Can Try
Restart the washing machine
Switch the machine off at the mains and leave it unplugged for at least 2 minutes. Reconnect the power, switch back on and restart the programme. If the fault was caused by a temporary glitch this may clear it.
Miele advises that if the fault persists after a reset, the appliance cannot be repaired without professional assistance.
