Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector from pump and unclip
cover to expose electrical connections
cover to expose electrical connections
Measurement:
Measure the resistance (continuity) across the pump harness:
Connections are;
CN2 pin 4 (brown) to the connection marked L at the pump wiring.
CN2 pin 1 (blue) to the connection marked N at the pump wiring.
Expected resistance is continuity (zero resistance)
across each wire of the harness.
Inspect harness and connectors for good overall condition.
Note:
Connector CN2 may differ in appearance
but test points remain the same.
