Dishwasher will not start. Light will not light up when you select the wash cycle. Dishwasher does has power to it. Checked connections to all electronics on the control panel. Any ideas???

Here are your parts
Replacement parts for Maytag MDB7601AWQ DISHWASHER- UNDERCOUNTER | AppliancePartsPros.com

See the attachment for the tech sheet

If you are sure that the control board is getting power and both door latch switches close then try the following.
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.

If that does nothing then you will have to check the the control panel/keyboard with a meter (see the tech sheet) as it could be either the control panel or the control board.
If it checks out OK then I would replace the control board.
Still a bit of a crap shoot but your odds are better.

With an ohm meter in hand, how do you determine if the control panel or control board is bad?
