The dishwasher will not start when you push the start key you can slect normal and the LED lights but when you push start nothing happens Usually it will blink at you telling it is set to go.

I have pulled out the keypad and cleaned the contacts and switches and it worked for 2 weeks before it acted up again. I pulled the keypad again cleaned contacts and switches and worked for another 4 days. I ordered a new key pad in the mean time and popped it in and nothing same symptom. I cleaned the ribbon cable contacts and checked the continuity which was good. I put it back together and no go.

As I am sitting in front of it trying to figure out the diagnostics and timing diagram I wiggled the door microswitch and it started up. This makes no sense as with the door open as you select the buttons it blinks at you once start is pushed and begins washing once the door is closed. This thing is has me baffled. I am going to replace the switch which is cheap but still don't understand what is causing the problem.

Can the main controller be intermittent like that? I pulled and flexed the boards and ribbon cable, pushed on the connections with no luck.

Any other ideas, before it started to act up the wash cycle seemed to be getting extremely long almost 90 minutes, could a flakey thermistor be the culprit?

Thanks any advice would be appreciated.

replace door micro switch or switches ,maybe intermittant problem

It's not the microswitch, I am thinking maybe a heater element fault locking out the controller. I will be checking heater and thermister next. It has to be something simple. Is there a key switch combo to reset the controller other than what is on the tech sheet?

I bypassed it and no change, however when I tested the heater element it was open. I out a new one in this afternoon and am washing a load now. With the new controller and hardwired micorswitch I was getting the clean light blinking 7 times just like the Whirlpool bulletin. I will let you know if the heater element was the fix. It seemed like everything I tried before would allow at least one load t go through before it would lock up.

Did you check the hi-limit thermostat (#30 on the break down diagram) for continuity? If it's open then it will give you the same symptoms - blinking Clean light.
