I have a Maytag Legacy Series dishwasher that is about 2 1/2 years old. About two months ago one of the LED lights on the control panel started flickering, then one stopped working all together. Now, all but one of the LED lights will come on if you press the buttons, but the dishwasher will not start.

Here are the parts
Replacement parts for MAYTAG MDBH945AWB Dishwasher - Undercounter |

Here is a tech sheet

Your problem is a pain to troubleshoot effectively as either the control board or the keypad (panel-con) can cause this, it is a bit of a crap shoot.
In this case I would lean towards the control board as LED's are being turned on.
I would check the keypad keys with a meter just to be sure that you do not have a stuck key (closed all the time)

I would try removing power from the unit for half an hour or so to see if it will reset.
Try running the diagnostics, though I doubt they will run.
Try the below cleaning procedure.
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.
