Dishwasher won't cycle

The unit runs but it will not cycle by it self. If you start it it will run in the wash cycle all night. if you move the control to rinse it will rinse only & so on. Do you think the timmer is the problem?

Hi Jeff,

Most likely the problem is a bad timer.

Here are the break down diagrams for the Maytag dishwasher Model MDB4100AWB
