Dishwasher not responding LG LDF6920ST

Recommended Posts

My LG dishwasher model  LDF6920ST quit working at the start of the month similar to what it had done 5 months earlier.  I had no response from the washer but had 120v to the PCB so I replaced that and the display PCB together and it resolved the problem.  When it quit working again I assumed the PCB was bad again and just got the new one installed.  It appeared to be working when I installed it and reconnected all the wires,  powered on scroll through selections etc but when I finished reassembling the door and went to test it again no response.  

I have 120v coming to the main PCB and 120v to the display PCB.  What could be causing the dishwasher to not respond?  could it be the noise filter even though I have 120v at the PCB?

Thanks any help is appreciated

Disconnect power.

Remove door panel/cover.

Deliberately examine all of the wires near the bottom of the door...for cracks/breakage (pulled apart).

The thin wires are more suseptible to damage.
