I have a kitchenaid dishwasher model KUDL02IRBS1. It stopped working with water remaining in the bottom. There are several green lights across the top panel and none of the lights, light-up. When I hit any button nothing happens. We went away for a week, when I returned the lights were on when I closed the door. It made it through part of a cycle and then quit again. Now I get no lights. There is power to the unit, and I am reading 118V at the circuit panel. I first pulled out the thermal fuse and tested it for continuity. It reads 0. To double check I put it back in and applied power. It reads 0 volts across the fuse and 118 on either side. So I am assuming it is good. The door switch appears good as well. Everything I read hinted that the thermal fuse was the likely culprit, but unfortunately it does not appear that it is. I did not know what else to check. I am assuming the possibility of a short because the fact that after it sat for a while, it worked for a short period. My guess is that I need to look at replacing the wiring harness or the circuit board. Any suggestions on how to further diagnose the problem, or what the likely cause is? Thanks.:confused:

Thank you very much. I will give it a try and get back. In the parts, I did not see the ribbon cable listed or shown. If that is broken is there a replacement part?

I checked P2,4,6,8 and they looked good. I cleaned the contact and did a visual inspection and everything looked good. I saw no corrosion. I did the keypad check and all buttons checked good. So I ordered the control board.

You said it was still a "crap shoot". So is there any further checks? Any other likely culprits? My wife will give me about a week before she either makes me pay to get someone to fix it, or buy her a new one. So I am better off ordering some extra parts. Do I need to check the wiring harness?
Thanks again.

OK, I will cross my fingers. Thanks again for the great help.

[COLOR="Blue"]Please Help. I ordered both the control board and the control panel (to be safe). I installed the control board and nothing happened. Then installed the control panel and still nothing.[/COLOR]
Damn!!!

I checked the power at the board. I am not very skilled at reading the tech sheet or using the multimeter, but here are my measurements[/COLOR]
[COLOR="Blue"]P2: 121[/COLOR] Neutral
[COLOR="Blue"]P3:0 [/COLOR] Heater thru board relay to P4
[COLOR="Blue"]P4: 121[/COLOR] Neutral thru a door switch
[COLOR="Blue"]P5: 0 [/COLOR] Motor thru a board relay to P4
[COLOR="Blue"]P6: 119 [/COLOR] L1 thru the fuse
[COLOR="Blue"]P8: 116[/COLOR] L1 thru the fuse and a door switch
[COLOR="Blue"]P9: 0 [/COLOR] Motor (other side) thru a board relay to P8[/COLOR]

I am a little confused by the above readings.
I need to know where the other meter lead was.
It cannot be on Neutral as you see a voltage on P2 which is the Neutral.
When measuring the voltage one meter lead should always be kept on the Neutral (a common reference point).

[COLOR="Blue"]at the thermal fuse I read 119 on each side and it goes from infinity to 0 when testing the resistance[/COLOR]
This looks good
[COLOR="Blue"]
at the door switch I read 119 on the tan side and 116 on the bl-w side[/COLOR]
This looks weird. When the switch is closed it should be a dead short so you should see the same voltage on both sides re: the same as the fuse.
I would pull the wires off it and check it for continuity

[COLOR="Blue"]I am desperate and irritable[/COLOR]
I can sympathize as I have been at the same point numerous times during my career. Sometimes a deep breath and counting to ten does not help but often leaving it and forgetting it for a day or so does the trick.
If you find yourself getting more and more frustrated and you start going in circles then it may be time for a second opinion.
