Our dishwasher won't run, and it seems to be the control panel or some part of it.

I am able to run something -- is it the diagnostic test? -- when you hit hi-temp scrub and Dry alternatively 5 times each. Water runs, the machine makes noise like it's running, a few lights go on, but then it stops and doesn't give any kind of code.

When I press the buttons on the control panel, none of the wash cycle lights will go on when I press them directly.

When I press heat dry or another option button, then press start, the light for normal wash (or another wash cycle) will go on, but the start button will only blink (as if the cycle were interrupted). No matter how many times I press start, nothing changes and nothing happens.

I see online that Kitchen-Aid has had a ton of problems with the control panels. This dishwasher is a little over 5 years old. Sigh.

Thanks.
