Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Disconnect connector CN8 from the PCB
Measurement:
Test 1:
Measure the resistance between the brown wire and the blue wire next to it on CN8.
Resistance should be approximately 225 Ohms.
Note: If appliance fitted with an ErP pump resistance should be significantly higher
Test 2:
Measure the resistance between the brown wire on CN8 to a suitable earth point.
Resistance should be greater than 1M Ohm.
Measure the resistance between the brown wire and the blue wire next to it on CN8.
Resistance should be approximately 225 Ohms.
Note: If appliance fitted with an ErP pump resistance should be significantly higher
Test 2:
Measure the resistance between the brown wire on CN8 to a suitable earth point.
Resistance should be greater than 1M Ohm.
Isolate as per TOPs P4
and refit as necessary
