Dishwasher: Why won't my dishwasher start?

You fill the dishwasher with dishes and shut the door, but the dishwasher doesn't start. To troubleshoot the problem, start by checking the door switch because the cycle won't start with a broken door switch. Watch our dishwasher won't start video for step-by-step instructions on testing the door switch.

If the door switch is okay, a damaged control panel, failed user interface control or broken electronic control board can prevent the dishwasher from starting. If your dishwasher uses a mechanical timer control, a failed timer can prevent the cycle from starting. Some dishwashers won't start if they don't fill with water. Our dishwasher not filling video provides troubleshooting tips for this problem.

Replace the dishwasher door latch assembly

The dishwasher won't start if the door isn't completely shut and latched. If the door doesn't latch shut, replace the latch mechanism. Even if the door latches fully, a problem with micro-switch in the door latch/switch assembly could keep the dishwasher from starting; in that case, replace the micro-switch.

Replace the dishwasher user interface control

The user interface control houses the selection buttons and display information such as the remaining cycle time. A defective user interface control won't light up or won't respond when you press its buttons. Because it's difficult to pinpoint the user interface control as the source of the problem when it won't light up or respond when you press its buttons, refer to the tech sheet for diagnostic tests (its' usually behind the service panel below the door) or have a service technician test the control. Replace the user interface control if it's defective.
