Check the ribbon connector cable FIRST!
« on: May 06, 2009, 08:21:53 PM »

Here's a lessons learned.  I was ready to purchased an electronic PC board for three year old Kenmore Dishwasher 665 series.  It similar to many KitchenAid, Whirlpool, etc. units as well.  I ran into the "classic" blinking light that you've undoubtedly read about on DIY help sites.  I read some comments upon further reading that it appeared that the touch pad or connector could explain the same behavior.  I pulled the PC board looked it over, the connectors, etc. and everything looked pristine.  Replaced the unit and reassembled it and found that the blinking lights had changed and I could even get the pump running in some crazy way.  I then assumed that it could very well be the connectors.  With this low voltage stuff .. it doesn't take much crud,corrosion, etc. to prevent a connection.  I cleaned the pins with iso alcohol, a fine, but stiff nylor brush, exercised the ribbon cable connection with angled nosed precision plyers and what do you know.  EVERYTHING is working perfectly.

As a side bar ... I found a used PC board for the unit on ebay for $4o.  Of course, I don't need it now but I wonder if I shouldn't buy it; the part number is 9744031. They're no longer made but a replacement you can buy NEW is 8530929. I'm keeping my eyes open for a touch pad for this general model on eBay as well, just in case.

Hi bobbyparagon,

Could you post the full model number of your dishwasher?

You can find the full model number on the model/serial number tag located on the dishwasher.
I believe you can find the tag on the inside of the door. It will start with 665 and end with eight digits.
