I have a Maytag Quiet Series 200 dishwasher. The 3 symbol on the face control panel light is on and starts flashing anytime you push any other button and it won't run. What is the problem?

Check the door switch.

press the heated button for 3seconds

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.

The control panel has bee locked. Press and hold the heated dry button for 3 seconds until the light next to the lock "3" button goes off. This feature is to prevent small children from starting it. Locking the controls works the same way, hold the heated dry button for 3 seconds will turn it back on.

1 month old call maytag should have a warranty

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.

Sounds like you have a bad Control Board

But with the price it cost, you might be better off buying a new dishwasher, preferably a different brand, cause that washer has some bad reviews

The 3 symbol on the face control panel light is on and starts flashing anytime you push any other button, and is full of water in the bottom of it. My wife says she stopped the washing cycle a couple of days ago but now it wont start back up.
This is a Maytag series 200

The dishwasher lights are all blinking, it starts randomly, like one in every 50 times you press the buttons. I have unplugged it to reset several times. Nothing is working. I'm looking for a solution to blinking lights and it not starting. is there any other way to reset the controls????
