Dishwasher Has No Power

This video from Sears PartsDirect shows what to do if your dishwasher won’t start because it has no power. Visit us at Or call 1-800-437-1673 to speak with a parts specialist. 

1. Check the power switch.

 Many dishwashers have an on/off wall switch, often next to the garbage disposal switch. Turn this switch on if it's off. 

2. Check the house circuit breaker. 

Because you often can't tell whether the breaker has tripped, reset the breaker for the dishwasher by shutting it off and turning it back on. Check the dishwasher now to see if it powers up. 

3. Check the power source. 

If your dishwasher has a power cord that plugs into an electrical outlet, make sure the power cord is plugged in. If so, check that the outlet is working by plugging in a small appliance like a blow dryer or night light to see if it works. If not, have an electrician repair the outlet. If your dishwasher doesn’t plug into an electrical outlet, it’s hardwired into the junction box.  Here’s how to check it: --Shut off the house circuit breaker for the dishwasher to disconnect electrical power, so you don’t get shocked. --Remove the mounting screws that hold the front access panel and toe panel in place and remove the panels. --Remove the screw from the junction box cover and pull off the cover. --Check the black wire connection and the white wire connection. Reconnect any loose or disconnected wires. Reinstall the junction box cover and then reinstall the bottom front access panel and toe panel. Restore electrical power to the dishwasher and see if it works. 

4. Check the user interface control wire harness. 

The control panel won't light up if the wire harness is disconnected. --Shut off power to the dishwasher. --Open the dishwasher door and remove the Torx screws from the outer edges of the inner door panel. So the outer door panel doesn’t fall off, support it with one hand as you remove the final screws. --Separate the outer door panel and control panel and rest the outer panel on the floor. --If the user interface control wire harness is unplugged, reconnect it. Reassemble the dishwasher and restore power. 

5. Have a technician diagnose the problem. 

If the dishwasher still doesn't power up, a failed user interface control, a failed electronic control board or a broken wire could be preventing the dishwasher from starting. Have a Sears service technician examine and repair the dishwasher. Additional diagnosis requires live voltage checks that require proper training.
