Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector X25 from the PCB
Remove the connector from the top solenoid (Black)
Remove the connector from the top solenoid (Black)
Measurement:
Test 1:
Measure the resistance between pin 1 (Blue) on connector X25 and the Blue wire on the Black solenoid connector.
Expect continuity.
Test 2:
Measure the resistance between pin 2 (Red) on connector X25 and the Red wire on the Black 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.
