Why does my dishwasher stop mid-cycle?

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 electronic control board

The electronic control board runs all dishwasher functions. If the electronic control board is getting voltage, but not operating properly, it should be replaced.

Replace the dishwasher control panel

When the control panel, also called the control console, becomes visibly loose or damaged, replace it. A stuck button can also cause the dishwasher to become unresponsive. A light may flash constantly on the control panel when a button is stuck.

Replace the dishwasher heating element

Replace the dishwasher heating element if it's visibly broken or not heating properly. If the heating element isn't visibly broke, check for a wiring failure, control failure or a blown fuse in the heating circuit before replacing the heating element--those issues could also be responsible for the heating element not working properly. You’ll also need to replace the heating element if broken element water seals allow water to leak through the bottom of the tub.

Replace the dishwasher vent and fan assembly

The vent opens during the drying cycle so the fan can direct hot, moist air out of the dishwasher through the vent opening at the bottom of the dishwasher door. Dishes won't dry as well if the vent fails to open or the fan fails to run. Also, the control panel goes blank and the dishwasher stops in the middle of the cycle if the fan fails. Replace the vent and fan assembly if either the fan or vent fails.
