Why Your Dishwasher is Stopping Mid-Cycle
A dishwasher stopping mid-cycle can happen for various reasons, often linked to a specific part or problem that will need to be resolved for it to run properly. Signs of a specific issue may include blinking lights, or starting and then stopping abruptly when filling. It's normal for dishwashers to pause mid-cycle to drain or heat water up, but there's a distinct difference between pausing and shutting off completely. Resetting your dishwasher or manually activating the drain can resolve it stopping mid-cycle, but the underlying cause must still be fixed, which means inspecting and testing a number of parts. Whether it's a simple fix like a clogged drain filter or a more complex issue like a malfunctioning door latch assembly or control board, this article will guide you through the required supplies, and instructions for diagnosing and fixing your dishwasher if it's stopping in the middle of a cycle.
General Problems that Cause a Dishwasher to Stop Mid-Cycle
It can be frustrating when your dishwasher stops mid-cycle, but understanding some general problems that can cause it will help you fix it quicker. We'll explore a few common issues, like a clogged filter and drain hose, low water pressure, and power failures, to help you resolve this stopping problem quickly and easily.
Clogged Filter and Drain Hose
A dishwasher's filter and hose, which are parts of the draining system, are used to trap food particles and debris from harming valuable parts like the pump, and remove dirty water from the dishwasher. If either of these parts is clogged, blocked, or damaged, the dishwasher will stop to avoid any overflow or potential damage to your home or its parts. If you see a series of lights or an error code appear when this occurs, note it and refer to your user manual for further information on the issue.
- Unplug your dishwasher and turn off its water supply.
- Open the dishwasher door and remove its filter. This may require a screwdriver or pliers to remove.
- Inspect the inside of the filter and its housing for any clogs caused by gunk or debris, and use a brush or sponge, and warm soapy water to clean the filter. If the filter is damaged, replace it immediately.
- Once the filter and its housing are cleaned, locate the dishwasher's drain hose underneath the sink, and inspect the drain hose for any clogs or foreign objects lodged inside.
- Place a large bowl or bucket underneath the drain hose opening and disconnect it from the sink drain. Lift the hose and water should rush into the bucket if there's any left. Then use a drain brush to clean it, or replace it if necessary.
- Reassemble the drain hose and filter assembly, start a cycle, and monitor it for any more stoppages.
Low Water Pressure
The pressure of the water being supplied to the dishwasher is important, because if it's too weak it will cause extended filling times and poor cleaning performance. This is why many dishwashers feature sensors that can accurately detect issues with it, and will stop your dishwasher mid-cycle if not enough water is being supplied.
- Locate the water supply valves in your home, and inspect its gauge. The reading should be between 14.5 to 80 psi, and a rating over 116 psi would be too high.
- If your water supply doesn't have a gauge, shut the valves closed.
- Unplug your dishwasher.
- Use a screwdriver to unthread the kick plate at the bottom of your dishwasher, and disconnect one of the fill hoses. Expect some water to spill out.
- Put the fill hose into a bowl or large bucket and turn the corresponding water supply valve until it's open.
- If the water strength going into the bowl or bucket is weak, you have an issue with your home's water supply. If the water flow is strong, continue reading this guide.
Power Failure
Dishwashers can stop suddenly during a cycle due to power problems, either with your home or the appliance itself. Check your circuit breaker for burn marks, and the dishwasher's power cord for damage like breaks or exposed wires. If necessary, contact an electrician to properly inspect and fix your home's circuit breaker or dishwasher's power cord.
What Parts You Need to Replace to Fix a Dishwasher That Stops Mid-Cycle
When your dishwasher abruptly stops mid-cycle, it's often due to issues with key parts like the door latch, float switch, heating element and fuse, inlet valves, drain pump, and electronic control board. We'll walk you through how to inspect, test, and replace each of these parts, so you can effectively resolve the mid-cycle stopping problem with your dishwasher.
How to Replace a Door Latch to Fix a Dishwasher That Stops Mid-Cycle
The door latch assembly is the most common culprit for dishwashers that stop mid-cycle because the door switch, handle, and latch mechanisms ensure the safe and proper operation of the dishwasher. When these parts break or stop working properly, they can cause the dishwasher to stop mid-cycle due to safety triggers that interpret the door as being open. Unless there's a specific code or indication otherwise, a bad door latch assembly in some models is indicated by the dishwasher stopping mid-cycle and blinking its lights. If your door latch assembly is broken or not working, you may also notice it's easy to open, and tough to close fully.
Supplies You'll Need
