Dishwasher rinse light just keeps blinking

[lance]

My dishwasher model # is GU1500XTKQ0
The rinse light won't stop blinking.
Do I need to replace the control board?

[bigbuck]

make sure what light is blinking, recheck & see if the clean light is blinking.
 
            thank you

Yes you are right it is the clean light.

[bigbuck]

the clean light blinks do to a problem in the heat curcuit, alot of times with this model, i find the door not closing properly due to a 2 switched door latch, make sure door is closing properly / only way to get it back to normal is do a test mode , hi temp wash-air dry- hi temp wash- air dry. this will make the dishwasher run again but does not fix problem. could be heating element, bi-metal or door switch.
 
 
let me know what you fine

I found the tech sheet with the wiring diagram on it.
I tested the heating element, door switches and the bi-metal thing with a multimeter.
The heating element showed some resistance. The door switch checked ok and the bi-metal was shorted.

The door seems to latch good. It's running now, but if it does it again what part do you think I should replace?

[bigbuck]

if the bi-metal showed shorted, replace the bi-metal or cleaning light will blink again after 1 load.

Correct me if I'm wrong, but the thermostat (bi-metal) between the heating element and control board will check closed (shorted) between the terminals. It has to be closed for power to get to the heating element.

If that is what they meant by shorted there may not be anything wrong with the thermostat/bi-metal.

[bigbuck]

shorted between the terminals, yes, but i,m relaying to ground.

if the bi-metal showed shorted, replace the bi-metal or cleaning light will blink again after 1 load.

Attaching some more info about the blinking cleaning light.

[lance]

bi-metal is shorted across the two ends that I unplugged the wires from.

read the attachment and wondering if I need to replace the control board.

[bigbuck]

no, control board does not need replacing, run full cycle with door closed tight, most likely cause i find is door not closing properly on the neutral switch to element.
 sometimes door rubbing on cabinet or countertop can cause this!
 
 bi- metal is good then!
