Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove the connector from the flow turbine
Remove connector X5 from the PCB
Remove connector X5 from the PCB
Measurement:
Measure the resistance of each of the wires on connector X5 (Pins 10, 11, 12) to the flow turbine connector.
Expect continuity / zero resistance on each test.
Also visually inspect the condition of the harness and its connectors.
Are the resistances measured as expected and is the harness in good condition?
