PDW9980NSS profile dishwasher fill no run except in service mode

Recommended Posts

Konbanwa,

It has been ten years since I first signed up on the old forums and you all have helped me many times.

I come to you again with a GE profile dishwasher model PDW9980NSS that will fill and then reset itself to start.

I believe that it is doing this because it knew today was Thanksgiving and company was coming.  It has likely been in the planning stages for months.

Anyhow here are details:

-If I enter service mode, I can fill it, run it for an hour and empty it all NO PROBLEM

-If I run factory test, sometimes it will get past the turbidity sensor portion and sometimes it won't.  The manual says this might be an abnormal value reading from the sensor, or a problem reading the eeprom.

-all the buttons work however in years past, the seal around the vent leaked into the door panel interior.  There is corrosion inside the button ribbon cable

Unless a malfunctioning turbidity sensor would cause the wash motor to not start, I figure I'm looking at an electrical issue.  The corrosion in the ribbon cable is worrysome, but all the buttons work.

It would seem something in it's process of running the steps is where it fails since it manually will run each step no problem.

I'm hoping to fix this the right way instead of just throwing parts at it.

 

What say you wise warriors?

Sorry- I forgot to mention that as it stops and 'resets' itself the the start. There is clearly a click of a relay from the control board.

Whether this relay is the cause of, or a result of the problem I do not know.

I'm thinking corroded ribbon is shorting start/cancel, causing the DW to cancel itself...
