All of the sudden one day I close my dishwasher and the lights don't come on. I tried turning off the breaker for a while, but nothing changed. I used an Ohm meter to test the door switch, which seems fine, but that's about the limit of my electrical abilities.
With your volt/ohm meter check for power going to the dishwasher. the power supply is located under the kick panel. the power wire may be shorted out due to poor installation. if you are not comfortable testing power, I would advise calling a professional. If no power is found at the power box (this has a power cord or electrical wire going to it) the problem lies within your house electric. if 120 volts is present, check for power @ the door switch. aftrer that you just need to follow the power wire and see where it stops
If this is a newly built house and new to you the builder may have put a light switch above your counter ,the one you didn't think went to anything, check for that! good luck with it!
since you have 120 volts going to the board there is only a few more things to check. first I would try to find the tech sheet, usually you can find it behind the kick plate or between the door panel, I think if you open the door remove the screws the inner panel will pick up. the tech sheet will help you put the unit in diagnostics. most likly you will need a control board or contol panel. these parts aren't cheap and generaly non-returnable. if you can't get the unit diagnostics following the proper steps you will need to replace one or both of the control parts

Thanks, i do have a voltage meter that lights up with live power. I tried and found power in the bottom panel, found it going into the door switch, after pressing the switch the power flowed through some little cylindars, then into the main circuit board. I also see the power popping up at various places on the circuitboard (the little black square towers, in particular). But that's the end of the trail. The display still doesn't come on and the buttons don't work. It's not a new house, 17 years old, and the dishwasher worked fine at least the last 4 years I've lived here. Not sure when it was installed.
