Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove connector CN10 from the PCB

Measurement:

Test 1.
Measure the resistances between the terminals on
the pump harness as per the table below:
Resistances should conform approximately to the table above.
Test 2.
Measure the resistance between terminals 1 and 2,
in turn, to a suitable earth connection.
Expect a resistance of greater than 1 MOhm for each test.
A reading of O.L on test 2 is acceptable as this is greater than 1 MOhm.
