Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to AC Volts 
Gain access to PCB (use Insulation Mat as required)
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Measurement:
Measure the AC voltage between the brown and blue wires at connector X3 on the PCB.
Expect the mains voltage to the pump to cycle, it should be present for 5 seconds and then absent for 5 seconds, this cycle will be repeated for up to 2 minutes.
Does the voltage to the pump behave as described above?
