I have a Maytag Jetclean Dishwasher model mdb4000aww. When I set the dail to Normal Wash which will should activate it to start nothing happens. If I push the door in just slightly it will activate and turn on. I have confirmed that the racks are pushed in all the way so I know there is nothing preventing the door from completely closing. If I eleveate the extra pressure of pushing the door in the maching will shut off. As soon as I push the door slightly it was activate and turn back on. Any ideas ?
