Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Remove the connector from the pump assembly
Measurement:
Test 1:
Measure the resistance between the bottom and middle pins on the pump.
Expect a resistance of approximately 237 ohms.
(If pump has been replaced with an ErP version
then resistance will be significantly higher)
Test 2:
Measure between the top and bottom pins on the pump.
Expect a resistance of 1 MOhm or greater.
Are the resistances as expected?
