Figured it was either the capacitor and/or motor. Ordered both parts to be sure. tried changing the capacitor first; same problem. Replaced the motor (leaving the new capacitor in place).

Dishwasher in a rental unit. Tenant says it won’t work. After verifying power to the appliance, I removed the front panel to access any possible internal fuses (bi-metal or otherwise). Troubleshooting process was simplified due to the discovery of a chewed through ribbon connecting the user control panel to a wire harness (which was also chewed up pretty badly) that connected to the main control board.

Do-It-Yourself Stories from Customers like You Broken door handle on Maytag dishwasher   Thomas S. • Meriden , KS • May 01, 2020

First of all, I should have taken it apart before I ordered parts. I thought all I needed was the handle and the door latch assembly. Ordered those parts and received them in 2 days. I soon found that there was another issue. The front panel has 2 plastic latches that the handle snaps in to. It also has a plastic stud that the handle screws to. One latch and the stud were broken. Then I ordered just the front panel - the plastic part that has the buttons and led lights. It arrived the next day.... Read more
