Maytag Quiet Series 300 - Control Panel doesn't work

You have a bad control board. Sensitive electronics and a high humidity environment do not go together. Replace the control board.

their is power to the dishwasher but the control panel does not light up and the machine will not start or run

I had no lights on my control panel, eventhough power was good.
I replaced the control panel ($265 part), it worked for 2 weeks, then I now have the same problem.
Frustrated, I am probably going to buy new from a different manufacturer.
Whirlpool/maytag does not warranty electronic parts if you do it yourself.

I had the same issue try hitting delay 1hr and start the 1hr was solid not flashing and an hr later it's running just fine. Think I need a new control panel but for now this is working.

We had the same issue with our Maytag quiet series 200 dishwasher. The Start/cancel button would not work all the time. We ended up removing the front panel from the machine and on the backside of the panel there is a plastic ultra thin ribbon cable that runs from the computer box to the push button control panel. We wiggled the ribbon cable and the start button began to work, but only if the ribbon cable was held in a certain position. So we super glued the cable in that position and it's been working consistently now.

Upon closer inspection the ribbon cable appeared to have 3 or 4 very tiny dark spots on the wires.
That would indicate to me that somehow moisture slowly eroded the tiny wires and bending the cable made the connections touch again, but for how long it will work like this is anyone's guess.
Also, it appears that the ribbon cable is permanently attached to the push button control panel. So you can't replace the ribbon cable itself without buying the hole front panel.

ck fuse / also ck it the hookup box behind the tow panel in middle . wire get hot and melt connectors . if you find bad wires make shure you remove bad ends and use new twist locks . mm

The electronic control panel has gotten wet and needs to be replaced (about $200 for parts plus about $200 for service call/labor) I just had mine replaced about 10 month ago, stopped using the type of dishwasher soap I had based on Maytag Service staff recommendation, stopped using hot wash to prevent high condensation at the door and now its broken again and in need of a new control panel again. You may be money ahead to go buy a new dishwasher that does not have the plastic encased control panel at the top. My understanding is the control panels are poorly engineered and made for most dishwasher manufactures by one of the mega electronic/appliance companies.

do any of the lights on the touch panel light up? if the answer is yes then you need a touch panel. if no light light up you might have a control board issue or a blown thermal fuse.

A water softner will not make the dishes any cleaner, it just makes it so they don't have water spots on them.
If the dishes are dirty, it is most likely that the nozzles (holes) in arms may be plugged.
Also check to make sure you are getting plenty of water to dishwasher. Make sure all water valves are full turned open.

If the control panel does not work all the time, it is very likely you have either a shorted wire, or a fualty main board which is very common in newer machines.

Order and replace the front panel only - not the control card. This will resolve the problem.
