Dishwasher: Stops mid-cycle

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 not been flipped to the Off position. Failure of a control board or the pump and motor assembly could also cause the dishwasher to stop mid-cycle.

These repairs may help solve your Dishwasher problem:

Replace the dishwasher door latch assembly

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

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

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 pump and motor assembly

Sump and motor assembly

Several situations can require the replacing the pump and motor assembly in a dishwasher. If the motor on the circulation pump fails, then the dishwasher pump won't run at all. Sometimes the motor runs but doesn't generate water pressure through the spray arms, because the damaged impeller or pump housing is damaged. The pump housing and/or the seals could also deteriorate or become damaged, causing the dishwasher to leak. Problems inside the pump and motor assembly can create abnormal noises in the dishwasher. In all these situations, the pump and motor usually must be replaced.

Replace the dishwasher heating element

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.

Replace the dishwasher bi-metal thermal fuse

Thermal fuse

The bi-metal thermal fuse protects the electronic control board and other components from a power surge. The fuse blows if there's a short to the metal cabinet or a short circuit in the wire harness of the dishwasher. A failed component can also cause the thermal fuse to blow. If the dishwasher control is completely dead even though electrical power is supplied to the dishwasher, the thermal fuse could be blown and should be replaced.

Replace the vent and fan assembly

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.

Replace the high-limit thermostat

High-limit thermostat

Located at the bottom of the dishwasher tub, the high-limit thermostat shuts off the heating element when it detects water temperature above 207 degrees Fahrenheit. A defective high-limit thermostat trips at a cooler temperature such as room temperature, preventing the heating element from heating. Dishes won't dry as well without heat. You can check for electrical continuity through the high-limit thermostat using a multimeter. If you measure no continuity at room temperature, replace the high-limit thermostat, because it tripped at room temperature and is defective.

Replace the dishwasher power supply control board

Power supply control board

Some models of dishwashers have a separate power supply control board that supplies electrical power to the logic board. If the logic control board or the components are not getting power, then the power supply control board should be replaced.

Clean the dishwasher circulation pump

Sump and motor assembly

A foreign object such as an unpopped popcorn kernel or a shard of glass sometimes migrates into the circulation pump where it causes a grinding noise and interfere with water movement through the pump and sump area. In that situation, you will need to dismantle and clean the circulation pump. The foreign object and/or any debris will need to be removed, and the pump will then need be reassembled.

Clear the dishwasher chopper blade area

Soil separator

A kernel of popcorn or a similar foreign object can drop into the chopper blade area of the dishwasher, causing a loud grinding noise when the pump runs. Remove the lower spray arm and the upper part of the dishwasher sump to access and clear debris from the chopper blade area. If the chopper blade is damaged, replace it.
