Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove pump electrical cover
Remove electrical connections from pump assembly

Measurement:


Test 1. Measure for resistance across live and neutral terminals of the pump.
Expect approximately 164 ohms or greater.
Test 2. Measure for resistance across live and earth terminals of the pump.
Expected resistance greater than 1Mohm.
(O.L is acceptable because it is greater than 1MOhm)
Are the resistances measured as expected?
