What the E20 / F20 Error Means
The E20 or F20 error code indicates that the machine has detected heating occurring outside of an expected heating phase. This is an abnormal heating event and the machine stops the cycle as a precaution.
Common Reasons This Error Appears
Faulty heating relay on the control board
If the relay that controls the heating element sticks in the on position, the element will heat when it should not. This is a common cause of this error.
Faulty NTC temperature sensor
If the temperature sensor is giving incorrect readings, the control board may believe heating is occurring unexpectedly.
Control board fault
In some cases the main control module may be sending incorrect signals to the heating circuit.
Safe Checks You Can Try
Restart the washing machine
Neff advises carrying out a reset by turning the machine off at the mains and leaving it for several minutes before restarting. This can clear a temporary fault and allow the machine to complete a cycle normally.
