Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove connector 20 from the PCB
Gain access to pump connections (top of pump)

Measurement:

Measure the resistance (continuity) across the pump harness leads, from connector 20 to pump connections (top of pump).
Expected resistance is continuity (zero resistance).
Note.
1. PCB connector numbers can be found on the board.
2. Ensure a good connection is made or misdiagnosis will occur.
