If the dishwasher stops before it's done, first try these simple troubleshooting steps:
Open and close the door to make sure it's latched.
Check whether the house circuit for the dishwasher and reset the breaker if it's tripped.
If a light switch on the wall near the dishwasher controls power to the dishwasher, make sure it's in the On position.
If these basic tips don't help, then a broken door latch, faulty control panel or failed electronic control board could be the problem.
In some models, a failed heating element causes the dishwasher to stop. A failed vent fan can be the problem when a Kenmore, Whirlpool or KitchenAid dishwasher shuts off or stops mid-cycle.
Follow the troubleshooting steps in our dishwasher won't start video to restart the dishwasher after it stops mid-cycle. Use the tips in our dishwasher has no power video if the dishwasher is dead after stopping during the cycle.
