Cabrio F51 Fault (Stored Fault Code F51) The Cabrio's F51 fault code flashes on the washing machine's display when there is a motor rotor position sensor (RPS) failure.
Check for good contact at the control Board and at the RPS. Sometimes disconnecting and reconnecting the RPS plug connection several times will clean off corrosion that may be affecting the contacts.

Search the internet for:

The most common reason for this code is :-

F51 error is caused by a faulty or blocked heater pressure switch. It is not a job for an unqualified person.

"The program is interrupted and the drain pump is operated. The display shows Technical fault F51. Call Service Department. The buzzer is activated for 2 minutes. "

On some machines the F51 is a slow or long drain error. Possibly a clogged filter in the drain pump or a bad pump. You did not provide enough information for me to offer any more help. I do not know the washer type, manufacturer, age, or model.

The F51 fault code on your Cabrio washer indicates that the control board is not sensing the proper drive motor spin. To clear the fault code, press the Pause/Cancel button.

Make sure that the drain hose is not stuck way down the stand pipe. This can cause siphoning of fill water which will inhibit proper motor rotation.

Check to see if the wash basket spins freely. If it does not, you may have an item of clothing stuck between the outer tub and the inner basket. This restriction in rotation will also cause an F51 fault code.

If these tips do not help you resolve the F51 problem, then you probably have a component failure. Possible failures include: wire harness or wire connection problem between the machine control and the RPS sensor (Rotor Position Sensor), a failed RPS sensor, a failed drive motor, and a failed machine control board.
