If the dishwasher stops during a cycle, first open and close the door to make sure it's latched. Check whether the house circuit to the dishwasher is 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. In other models, a failed vent fan can cause the dishwasher to stop 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.
These repairs may help solve your dishwasher 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.
One reason a dishwasher won’t start could be a broken dishwasher latch assembly—the assembly includes the latch itself and a microswitch. You can replace the latch assembly yourself in about half an hour, following the steps in this repair guide and video.
Because the electronic control board runs every stage of the dishwashing cycle, it's hard to know if the problem is the board or something it controls. If you or a repair technician determines the dishwasher control board is faulty, this repair guide and video show how to install a new one.
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 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.
Your dishwasher gives some clear clues if the dishwasher's heating element stops working: the water doesn't get hot (no steamy kitchen) or your dishes don't dry. You can replace the heating element in less than an hour, following the steps in this DIY repair guide and video.
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.
The dishwasher fan blows hot air from the dishwasher. If the fan fails, the control panel lights turn off and the dishwasher stops. This DIY repair guide and video shows how to install a new fan and vent assembly in less than 30 minutes.
