  On Miele F51 is pressure switch error.
  
  The pressure switch is located in the drain system. Its function is determining if there is water inside the tub.
  
  Trip the circuit breaker or disconnect the power cord for a couple of minutes. Inspect the drain system for blockage. The pressure switch can be tested by a technician bypassing it.
  
  To get parts or repair service, call the number listed on the user manual.

    hi,
    
    F51 fault is more than likely the heater relay is faulty but it could be your circulation pump is jammed up. if you are confident you can easily replace the replace the relay if it is faulty. you would need to put a meter across the terminals. if it is ok then the pump is blocked. if you are not confident you would require a service call. Miele have there own deadicated service team if you live in a metro area
    
    hope this helps.

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.

Here is an earlier Fixya answer addressing the query:

Whirlpool cabrio error code f51 what does it mean

Sensor is item 20 below. Clean it.

F51: Pressure Sensor
Symptom

The program is stopped, the water intake valve is closed, and the drain pump is
switched on for 120 seconds.

Electrical defect in analog pressure sensor (ADS). The values are out of range.
x

This will usually require a professional to repair.

Search the internet for:

Make + Model + the word "F51"

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. "

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.
