Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Disconnect connector PL6 at the PCB

Measurement:

Test 1:
Measure the resistance across the brown and blue wires at PL6.
Resistance should be approximately 75 Ohms.
Test 2:
Measure the resistance across the orange and blue wires at PL6.
Resistance should be approximately 32 Ohms.
Test 3:
Measure the resistance across the yellow wires at PL6.
Resistance should be approximately 1.2 Ohms.
Note:
Ensure you consider the resistance of the fused probes when carrying out this test, especially on test 3.
