Door Latch Issues
The door latch plays a vital role in your LG dishwasher’s operation. If the latch is faulty, the dishwasher may start and then stop abruptly. This happens because the machine senses the door is not securely closed. A damaged or loose latch can confuse the control board and halt the washing cycle.
Understanding door latch issues helps you fix the problem quickly. It prevents interruptions and ensures your dishwasher runs smoothly every time.
Signs Of A Faulty Latch
One sign is the dishwasher stopping soon after starting. The door may not stay closed properly. You might hear clicking sounds as the latch tries to hold the door. Sometimes, the door feels loose or does not lock tightly. These symptoms often mean the latch needs attention.
Checking Door Closure
Check if the door closes fully and clicks into place. Gently push the door and see if it stays shut. Look for any visible damage on the latch or door frame. Dirt or debris can also block the latch from closing correctly. Clean the latch area to ensure smooth operation.
Replacing The Latch Assembly
Turn off power to the dishwasher before starting. Open the door and locate the latch assembly. Remove screws holding the latch in place carefully. Disconnect any wires attached to the latch. Install the new latch assembly by reversing these steps. Test the door to make sure it closes firmly and the dishwasher starts properly.
Clogged Filters And Spray Arms
Clogged filters and spray arms often cause problems in LG dishwashers. Dirt, food particles, and debris can block these parts. This blockage stops water from flowing properly. The dishwasher may start but then stop suddenly. Cleaning these components helps the machine work better and last longer.
Effects On Dishwasher Performance
Clogged filters reduce water flow inside the dishwasher. This lowers cleaning power and leaves dishes dirty. Spray arms with blocked holes cannot spin freely. Water jets become weak or uneven. The dishwasher may stop mid-cycle to protect its motor. Over time, the motor can overheat and break down.
Cleaning The Bottom Filter
Remove the bottom rack to access the filter. Twist the filter counterclockwise to unlock it. Pull the filter out carefully to avoid spilling debris. Rinse the filter under running water. Use a soft brush to scrub away stuck particles. Check the filter housing and clean any residue. Reinstall the filter by locking it in place firmly.
Clearing Debris From Spray Arms
Take out the spray arms by unscrewing or snapping them off. Inspect the holes for any clogs. Use a toothpick or small brush to clear blocked holes. Rinse the spray arms with water to remove loosened debris. Make sure the spray arms can spin freely before reinstalling. Properly cleaned spray arms improve water coverage and dish cleanliness.
Performing A Hard Reset
Performing a hard reset on your LG dishwasher can fix many common issues. It clears minor glitches in the control board. This process is simple and often restores normal function quickly. A hard reset can stop the cycle from starting and then stopping unexpectedly.
Many problems like unresponsive buttons or error codes disappear after a reset. It is a quick step before calling for repairs. Understanding when and how to reset helps keep your dishwasher running smoothly.
When To Reset
Reset your LG dishwasher if it starts and stops suddenly. Also try resetting when buttons do not respond. If you see error codes or the dishwasher acts strange, a reset can help. Perform a reset after cleaning filters or checking the door latch. Avoid resetting too often as it does not fix hardware issues.
Step-by-step Reset Guide
- Turn off your dishwasher by pressing the power button.
- Unplug the dishwasher from the power outlet.
- Wait for 5 minutes to let the system fully power down.
- Plug the dishwasher back into the outlet.
- Press the power button to turn it on.
- Start a new wash cycle to test if the problem is fixed.

Float Switch And Water Inlet Valve
The float switch and water inlet valve play key roles in your LG dishwasher’s operation. They control water flow and ensure the dishwasher fills correctly. Problems with either can cause the machine to start and stop unexpectedly.
Understanding these parts helps with basic troubleshooting and maintaining your dishwasher’s performance.
Role Of The Float Switch
The float switch acts as a water level sensor inside the dishwasher tub. It rises with the water level. When the water reaches a certain height, the float switch signals the machine to stop filling. This prevents overflow and water damage.
If the float switch is faulty, the dishwasher may not fill properly or may stop mid-cycle. It acts as a safety device to control water intake.
Identifying A Stuck Float
A stuck float can cause the dishwasher to stop working. Dirt or debris may trap the float in the down position. When stuck, it tells the machine the water level is too high, even if it is not.
Check the float by gently moving it up and down. It should move freely without resistance. Clean the area around the float to remove any dirt or buildup that may block its movement.
Inspecting The Water Inlet Valve
The water inlet valve controls water flow into the dishwasher. It opens to let water in during the wash cycle and closes to stop it. A faulty valve can cause no water to enter or cause leaks.
Look for signs of damage or blockages in the valve. Listen for a clicking sound when the valve opens. Testing the valve with a multimeter can confirm if it is working properly.
Electronic Component Failures
Electronic component failures often cause LG dishwashers to start and then stop suddenly. These parts control the dishwasher’s key functions. When they fail, the dishwasher may not complete its cycle. Understanding common electronic issues helps in troubleshooting effectively.
Most electronic problems involve the thermal fuse, motor relay, or control board. These components protect the dishwasher and control its power and operations. Faults in any of these parts can interrupt the cycle and cause the dishwasher to stop.
Thermal Fuse And Motor Relay Problems
The thermal fuse prevents overheating by cutting power if needed. When it blows, the dishwasher will not start or will stop quickly. A faulty motor relay can also stop the motor from running. This causes the dishwasher to halt mid-cycle. Both parts need testing if the dishwasher stops suddenly.
Control Board Malfunctions
The control board acts as the dishwasher’s brain. It sends signals to start and stop the machine. If it malfunctions, the dishwasher may start and then stop unexpectedly. Control board errors can be caused by power surges or water damage. Resetting or replacing the board may be necessary to fix these issues.
When To Seek Professional Help
Diagnosing electronic failures can be tricky without proper tools. If basic checks do not solve the problem, call a professional. They have the right equipment to test and replace faulty components safely. Attempting repairs without experience can cause more damage or void warranties.

Basket Positioning
Proper basket positioning in your LG dishwasher is crucial for smooth operation. Incorrect placement can cause the door to not close fully, leading the dishwasher to start and then stop unexpectedly. This section explains how basket placement affects door closure, how to adjust the bottom basket, and ways to prevent cycle interruptions.
How Basket Placement Affects Door Closure
The dishwasher door must close tightly to start a cycle. If the basket is not in the right position, it can block the door. This slight blockage signals the dishwasher to stop for safety. A basket pushed too far out or loaded unevenly can cause this problem.
Check that the baskets slide in smoothly without forcing. The door should close easily without resistance. Proper basket alignment helps the door latch securely and prevents the dishwasher from stopping mid-cycle.
Adjusting The Bottom Basket
The bottom basket often holds heavy items and can shift during loading. Make sure the basket is fully seated in the rails. Adjust the wheels or guides if the basket does not slide evenly.
Remove large or oddly shaped items that might stick out and block the door. Load plates and pans flat to avoid tilting. Proper adjustment reduces the chance of door interference and cycle interruptions.
Preventing Cycle Interruptions
Cycle interruptions occur if the dishwasher senses the door is open. Secure basket placement keeps the door closed and the cycle running. Avoid overloading baskets to maintain space for the door to close.
Regularly check baskets for damage or misalignment. Replace broken wheels or guides to keep baskets stable. Maintaining correct basket positioning ensures your LG dishwasher starts and finishes each cycle without stopping.
