Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Disconnect leads from pilot solenoid (left hand plug)
Measurement:
Test 1:
Measure the resistance across the two spades of the pilot solenoid.
Resistance should be approximately 1.5kΩ.
Test 2:
Measure the resistance between one of the spades for the pilot solenoid to a suitable earth point.
Resistance should be greater than 1MΩ (or O.L).
