I have a Maytag quiet series 300, model # MDBTT60AWW. The front control panel have some green lights on but the start/cancel button won't work. The dishwasher will work for 5 days and quit for 2-3 days then work again. I tried to reset the main electrical panel hoping the dishwasher will reset too but it didn't work. I opened the panel on the front door to see if water is getting into the electronic panel but it is dry. I'm wondering if it is the front control panel itself is the problem. I wanted to make sure I change the right part so I won't have to waste money on the part that don't need to be changed. Please HELP!

The F73 error code means that one or more of the control buttons on the touch pad is defective. You can clear the error code by the pushing clear/cancel button, if it doesn't reoccur all is well. If it ever happens again, you will need to replace the touch pad

Find your circuit breaker for your dishwasher and turn it off for 3-5 minutes. Turn it back on, then turn on your dishwasher. If this works, after the complete cycle of your dishwasher, you have to turn it off manually by pressing "on" botton then press it 1 more time to cancel; this will turn off. The defect is, probably the moisture built up in the control board causing it to ground some of the connections. Suggestion for the manufacturer, insulate the control board to prevent absorbing moisture.

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.

While I am not directly aware of the controls on the dishwasher I'd unplug it for a minute or two to see if the control reboots (for lack of a better term) I've seen many electroic devices that on occasion have this type of problem and simply taking the power from it may correct it.
I hope this helps,

in such cases it is always the control panel(touch panel) that needs to be replaced.it is very simple 2 chg and u could save lot of money.to chge cntrl panel ,open the door and remove all the screws around the white plastic part of door.then pull apart the inner part from outside part.the cntrol panel is held to outer panel with 4 screws.b4 that remove 2 screws holding the control board to panel.do not forget 2 unplug the unit from power b4 doing anything.

Mine was doing the same thing and I just pressed and held down the heated dry button until the light went off. Then I was able to start my machine as usual. Hope this works for you.

Replace the control panel, not the control board, the control panel

I had the same problem. The lock button light was on, nothing happened when pressing start, cancel, etc. I also tried holding the heated dry button (lock) for 3 seconds and no luck UNTIL holding down for three seconds while also pressing the cancel button. I was then able to start cycle as normal.

we have a model mdvtt53aww1 and you can push three buttons and will light up the hi temp wash, heated dry and sanitize is there a code make it start
