Dishwasher Stopping Mid-Cycle? All the Easy Fixes You Need to Know
Nothing is a more valuable timesaver than a dishwasher. This appliance makes quick work of cleaning everything from dishes to glassware and everything in between. But when it suddenly stops mid-cycle, that can put a damper on your day. While an open door or a tripped circuit is a common culprit, there are other problems that can cause this issue. Our friends at Sears Parts Direct have some quick fixes to get your dishwasher running smoothly again.
Replace the Door Latch Assembly
Your dishwasher won't run if it detects that the door is open. If you close the door tightly but the latch doesn't shut, the door latch assembly may be damaged and should be replaced. Even if the latch does properly close, the micro switch could still fail to signal to the dishwasher that the door is closed. If that is the case, the micro switch should be replaced.

Replace the Electronic Control Board
The electronic control board is responsible for controlling all of the dishwasher's many moving parts. If the electronic control board is receiving electricity yet fails to communicate with other parts, it may be damaged or defective. This can cause the machine to stop mid-cycle or not start at all. In this case, it needs to be replaced.

Replace the Control Panel
If the control panel on your dishwasher shows visible signs of damage or has become loose from the unit, it could fail to signal a cycle from continuing or beginning. Additionally, a single button or group of buttons could get stuck, which might also prevent the dishwasher from continuing to run. When a button is stuck, you might notice a flashing light on the control panel. If your control panel is damaged, loose or stuck, it may need to be replaced.

Replace the Pump and Motor Assembly
A faulty pump and motor assembly can cause a dishwasher to stop suddenly. There are many different factors that hinder this portion of the machine. If your dishwasher has a damaged impeller or pump housing, this could cause the motor to fail to produce adequate water pressure through your dishwasher’s spray arms. If the motor on the circulation pump fails entirely, your dishwasher may fail to run at all. Seals inside could also deteriorate over time, which could also cause your dishwasher to leak. In any of these scenarios, it's best to replace the pump and motor assembly.

Replace the Heating Element
The heating element is responsible for heating the dishwasher tub, which works to both get your dishes clean during the cycle and dry at the end of it. If the machine stops mid-cycle, examine your heating element for visible signs of damage or disfunction. Make sure to check for any faulty wiring, issues with the control settings or a blown fuse in the heating circuit.

Replace the Bi-Thermal Fuse
A bi-thermal fuse helps to protect various parts in your dishwasher from a power surge. When this fuse blows or is even slightly damaged, this can damage other parts in your appliance, causing it to stop mid-cycle or not run at all. If this component is broken, make sure to replace it immediately.

Replace the Vent and Fan Assembly
Once your dishwasher begins its drying cycle, the vent opens so the fan can move all of the hot air and moisture out of the tub. When the fan breaks down, your dishwasher will stop in the middle of a cycle. If either that or the vent fails, it's time to replace them.

Replace the High-Limit Thermostat
When the water in your dishwasher tub reaches a certain temperature, the high-limit thermostat turns off the heating element to prevent the unit from overheating. If the high-limit thermostat malfunctions, this could cause your dishwasher to operate at a cooler temperature by turning off the heating element too soon. Higher temperatures help your dishes dry faster during the cycle, and cooler operation could prevent the drying cycle from completing. To troubleshoot your high-limit thermostat, use a multimeter to see whether electricity is running properly. If no electricity is measured at room temperature, you will need to replace your high-limit thermostat.

Replace the Power Supply Control Board
Certain dishwashers have a power supply control board, which sends electrical power to the logic board. If the supply board is broken, different parts throughout the machine will not have power. This can cause your dishwasher to stop mid-cycle or not turn on.
Examine and Clean the Circulation Pump
Any loose debris such as leftover food particles can make their way into the circulation pump. This might affect the transfer of water through the pump and sump area during a cycle, causing your dishwasher to stop mid-cycle. Locate the circulation pump and clean it thoroughly of any trapped debris. If you notice visible signs of damage to your circulation pump while cleaning, it should be replaced.

Examine the Chopper Blade Area
If any loose food particles left on your dishes or silverware fall into the chopper blade section of your dishwasher, it can stop the machine. You'll know there is a problem if you hear a loud, grinding noise. To access the chopper blade area, remove the lower spray arm and upper part of the sump, and make sure the area is clear of anything that might be stuck. If the chopper blade has become damaged due to excessive grinding, it should be replaced.
