What the F51 Fault Code Means
The F51 fault code indicates a problem with the pressure sensor or level switch — the component responsible for measuring and monitoring the water level inside the drum. Without accurate water level information, the machine cannot safely manage the fill and drain processes and will stop the cycle.
Common Reasons This Fault Appears
Faulty pressure sensor
The pressure sensor itself may have failed and is no longer providing accurate water level readings to the control board.
Blocked pressure sensor tube
A small rubber tube connects the pressure sensor to the drum. If this tube becomes blocked with detergent residue or debris, the sensor cannot take accurate readings.
Disconnected or split pressure tube
If the pressure tube has come loose from either end or developed a split, the sensor will not function correctly.
Faulty level switch
The level switch relay may have worn out and is no longer responding correctly to pressure changes.
Wiring fault
A loose or damaged connection to the pressure sensor can cause the control board to receive incorrect or no readings.
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. A power reset can sometimes clear a temporary sensor fault.
Run a drum clean cycle
Running a hot empty cycle with a washing machine cleaner may help clear any detergent residue that could be affecting the pressure tube.
