Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector CN303 from the PCB and electrical connector to the diverter valve actuator
Measurement:
Measure the resistance across each wire of the harness of removed diverter actuator connector and CN303 connector.
(e.g. pin 1 CN303 to pin 1 diverter actuator connector)
Expect continuity / zero resistance on each wire.
Also visually inspect the condition of the wiring and connectors.
Note.
Ensure a good connection is made during resistance tests.
