Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove plug from the pump

Measurement:

Test 1:
Measure the resistance between the top and middle connections at the pump.
Resistance should be approximately 225Ω.
If different pump has been fitted resistance may be
different, ErP pumps will be significantly higher
Test 2:
Measure the resistance between the top and bottom connections at the pump.
Resistance should be greater than 1MΩ (or O.L.)
