Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Disconnect connector X11 from the PCB
Measurement:
Test 1:
Measure the resistance between the blue and brown wires on the right hand side of X11.
Resistance should be approximately 220 Ohms.
(if an ErP pump is fitted resistance will be significantly higher)
Test 2:
Measure the resistance between the brown wire to a suitable earth point.
Resistance should be greater than 1M Ohm.
