Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove connector X25 from the PCB
Remove the connector from the bottom solenoid (White)

Measurement:

Test 1:
Measure the resistance between pin 7 (Blue & Black) on connector X25 and the Blue wire on the White solenoid connector.
Expect continuity.
Test 2:
Measure the resistance between pin 8 (Red) on connector X25 and the Red wire on the White solenoid connector.
Expect continuity.
Also inspect the condition of the harness visually to check
there are no sections of damaged insulation.
Note:
Each pin on the PCB connector is numbered.
