Set Appliance State:
Set Multimeter to Resistance 
Isolate Mains Power to appliance as per TOPs P4
Disconnect connector CN3 from Sequence Control PCB
Disconnect connector CN3 from Sequence Control PCB
Measurement:
Measure the resistance across connection MN (Brown wire) and connection ML (Blue wire) on the disconnected plug.
The resistance should be approximately 4.8Kohms.
Note 1:
Measurements taken at the disconnected plug not at the PCB.
Note 2:
On some models sequence control PCB may have only numbered connections in which connections will be numbered 11, 12 & 13 test to be carried out on Brown and Blue wires on the plug that were connected to connections 11 and 12.
The resistance should be approximately 4.8Kohms.

Isolate as per TOPs P4
and refit as necessary
