Thread: GU1200XTLQ1 Rinse Only LED Blinking

Hey everyone,

My GU1200XTLQ1 Whirlpool Gold Dishwasher is about 5 years old and is just now giving me problems. The dishes don't seem to clean very well anymore, I don't think it completes a full cycle. The other day I opened up the dishwasher and it hadn't full drained (LED's blinking).

Right this moment, the "Rinse Only" LED is blinking. Nothing happens if I press any of the other buttons, except for the "Cancel" button -- it just begins to blink in unison with Rinse Only. I tried turning off the power to the dishwasher for 60 seconds, but nothing happens -- it goes back to the blinking.

I have done some research online and have found the following resources potentially useful to my problem:

tech sheet

My problem matches a note in the first link: "NOTE: If the line voltage is normal and a single Cycle, Option or Rinse Only light is blinking, the problem is usually a stuck or shorted keypad on the active overlay, not the control. A resistance check of the active overlay should always be made, using the keypad matrix in the product tech sheet, prior to replacing the electronic control.

I am 20 years old studying mechanical engineering so I would like to fix this on my own and avoid ridiculous servicing charges. Is the problem the control panel? Where can I find the replacement part? How do I put the machine into service mode, etc?

Thanks alot,

Javier
