Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector X4 from the PCB
Remove the connector from the diverter valve motor
Remove the connector from the diverter valve motor
Measurement:
Measure the resistance across each of the wires in the diverter valve harness.
Expect continuity / zero resistance on each of the wires in the harness.
Also visually inspect the condition of the harness.
Are the resistances measured as expected and is the harness in good condition?
