The control touchpads do not respond when pressed. When I press the start button on the front, the dishwasher starts on the last cycle that I selected before the controls stopped working and the indicator light next to that setting lights up. HELP!

Here are your parts
Replacement parts for MAYTAG MDB8751BWS | AppliancePartsPros.com

Here is an operators manual
http://shared.whirlpoolc...0Guide%20-%206920186.pdf

And here is a tech sheet
https://www.servicematters.com/d...atic%20-%20W10128608.pdf

First try to unlock the keypad Page 10 of Operators Manual

Next try removing power from the units for half an hour or so to see if it will reset.

Next try to run the diagnostics on the tech sheet

Next RIBBON CABLE CLEANING
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.

Next check the keypad switches with a meter, see the tech sheet
Also check the wires going from the control to under the unit.
There has been a lot of problems with rinse aid leaking and causing all sorts of problems.
