Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Gain access to PCB (use Insulation Mat as required)
Remove X14 pump connector from the PCB

Measurement:

Test 1.
Measure for resistance across pins 1 (Brown) and 2 (Blue) of X14.
Expected resistance greater than 1MOhm (or O.L).
Test 2.
Measure for resistance across pin 1 (Brown) and a suitable Earth
Expected resistance greater than 1MOhm (or O.L).
Test 3.
Measure for resistance across pin 2 (Blue) and a suitable Earth
Expected resistance greater than 1MOhm (or O.L).
