Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector X2 from the main PCB
Remove the connector from the flow turbine assembly
Remove the connector from the flow turbine assembly
Measurement:
Measure the resistance between each of the pins listed below on connector X2 and the corresponding wire on the flow turbine connector.
Expect continuity (zero resistance) on each test.
Also inspect the condition of the harness visually for general condition and any signs of damaged insulation.
| Connector CN12 | Flow Turbine Connector | Pin 5 (white) | White |
| Pin 6 (Blue) | Blue |
| Pin 7 (Red) | Red |
Expect continuity (zero resistance) on each test.
Also inspect the condition of the harness visually for general condition and any signs of damaged insulation.
