Kenmore Dishwasher will not start - no diagnostic code -Solved

Hi, Some perhaps silly questions. But as it seems to work OK when using the diagnostic program and you have replaced the control board I'm thinking about the control panel. Have you tried different wash cycles to see if it is a control button that is the problem? Have you pressed the time delay button in case the delay time light is not showing but the delay time is activated again due to a faulty button?

Well I get the same result with both control boards that I have now. No cycle will start. The lights above the button light up for most. Normal Wash, HE Wash, Pots and Pans, China, but not 1-hour wash. Also, the delay start button that toggles between the 2, 4, and 6 hour starts does not light up. I can run the diagnostic and all lights come on before it runs the diagnostic test.

When running the test, it goes through all of the cycles, water is coming in, it is draining, the heating element get's hot. but I still get no code after it runs. I had the bottom off and everything under the dishwasher looks like it is running.

One other thing to note - is there any high temperature setting that could be having an issue. We did have an issue with our hot water heater and the water was getting VERY hot. Not sure if that could have caused any other issue that the diagnostic test isn't registering.

It will be hard to prove the problem but if you remove the panel from the dishwasher you may be able to access the buttons themselves and with an Ohmmeter prove whether the button contacts (especially the delay time button is OK.Given the panel is connected by a flex cable tothe control board and looking at the part in this link http://www.searspartsdirect.com/part-num... it doesn't seem to have too many wires so it probably has some sort of matrix arrangement (like a keyboard in a PC) to denote which buttons are pressed.

As the new control board didn't fix the problem, find out if you can return it for a refund and get the Control Panel instead if you haven't got the equipment to test it first.

Ok - I'll take a look when I get home tonight to see if I can Ohm out the butons that aren't lighting up. Thanks for the idea! Will post tongith or in AM what I find.

Anyone else with other ideas is appreciated!

Hi, Forgot to add the buttons may be OK in themselves, it may be a short circuit between two or more connections leading from the buttons to whatever connects to the flex cable. It may even be diode leads that are touching for example.
