Last night we couldn’t get the dishwasher to start. Most buttons on the control panel would not respond. For the past few weeks, the lights to indicate that the dishes were clean and sanitized failed to come on after the washing was complete. Tonight, we hit the start button and while no lights came on, the dishwasher did start. From what I’ve read, it seems that Maytags have had problems with control panels. Any ideas on how we should proceed?
Here are your parts

Here is the tech sheet

And a manual

Will probably be the keypad or the control board.
It is a biot of a crap shoot as to which one so check the keypad with a meter (see the tech sheet) if it checks out OK then I would go with the control board first.
You could try the following cleaning method but this is a long shot unless the connector has a lot of dirt in it.
Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
My washer is giving an od code on the display. The lid won’t lock and the service paperwork say to go to the "lid lock test". Can’t find this test anywhere in the paperwork. Does anybody have any suggestions?
What is the model number?
