Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector CN09 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.
Note.
A reading of O.L on test 2 is acceptable as this is greater than 1 MOhm.
