I have a maytag MDB8600AWQ dishwasher that started to start a wash cycle on its own in the middle of the night. At first I though that someone may have accidentally set it up for a time delay wash, but the next day the dishwasher started 2 different times and on its own. I have tried turning the power off and back on, but that did not help. Now I cannot use it at all. Some of the buttons don't do anything, and the display only shows random lights flashing. I suspect either the control panel, or the board. I replaced the control panel once already for another issue a couple of years ago. Please help. Note, the S/N is 20972779CT. If I need a board or control, please advise which P/N. Thanks.
