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

Measurement:

Test 1:
Measure the resistance between the pump terminals as
per the table below:
Resistances should conform approx. to the table above.
Test 2:
