Went to start the dishwasher and it wouldn't start. Could select the cycle I wanted but couldnt select the start button. Reset the breaker still nothing. Removed the panel cover and wiggled the connectors. Would then let me select start, but then just ran for hours and wouldn't stop. I reset power to stop, but could not get it to start again. I read many blogs I believe it is either the control panel or board. Tried to get the tech sheet to check the control panel with volt meter but PDF is not found. Should I try cleaning all the connections first before I order parts and which one part would you try first. Thanks Joe. Model mdb6759aws1 maytag
