Common Causes
A dishwasher that keeps turning off unexpectedly often has simple causes. Understanding these common issues helps fix the problem quickly. Most cases relate to drainage, door security, or power supply. Troubleshooting these areas saves time and avoids costly repairs.
Clogged Drain And Filter
A clogged drain or filter stops water flow inside the dishwasher. This blockage can cause the machine to shut off mid-cycle. Food particles and debris build up in the filter over time. Removing the lower rack and cleaning the filter helps restore proper drainage. Check the drain hose for kinks or blockages too. Keeping the drain clear prevents interruptions during the wash cycle.
Faulty Door Latch
The door latch ensures the dishwasher stays closed during operation. A loose or broken latch triggers a safety shutdown. The dishwasher stops immediately to prevent leaks or damage. Check the latch for wear or misalignment. Make sure the door closes tightly and locks securely. Replacing a faulty latch can solve frequent power-offs.
Power Supply Issues
Power problems cause the dishwasher to turn off suddenly. A tripped circuit breaker or blown fuse cuts electricity to the appliance. Inspect the home’s electrical panel for any switched-off breakers. Also, examine the dishwasher’s power cord for damage or loose connections. Resetting the breaker or fixing wiring issues restores power. Reliable power supply is vital for smooth dishwasher operation.

Basic Checks
Performing basic checks can help identify why your LG dishwasher keeps turning off. Simple issues often cause this problem. Checking these basics first can save time and avoid unnecessary repairs.
Reset The Dishwasher
Unplug the dishwasher or switch off the circuit breaker. Wait for about five minutes. Turn the power back on to reset the control board. This can clear minor electrical glitches causing the shutdown.
Inspect Power Supply
Check your home’s electrical panel for tripped breakers or blown fuses. Examine the dishwasher’s power cord for cuts or damage. A faulty power supply can cause the dishwasher to stop suddenly.
Check Door Latch
The door latch ensures the dishwasher door is closed properly. A loose or broken latch can stop the dishwasher mid-cycle. Press the door firmly and listen for the latch click. Replace the latch if it does not hold securely.
Drainage Problems
Drainage problems often cause an LG dishwasher to turn off unexpectedly. Water must flow out smoothly for the dishwasher to complete its cycle. Blockages can trigger safety features, causing the machine to stop. Checking and fixing drainage issues can restore proper function quickly.
Clean The Filter
The dishwasher filter traps food particles and debris. A clogged filter blocks water flow and may cause the dishwasher to shut off. Turn off the power before removing the lower rack. Take out the filter and rinse it under running water. Use a soft brush to remove stubborn dirt. Clean filters improve drainage and prevent mid-cycle stops.
Examine Drain Hose And Air Gap
The drain hose carries wastewater away from the dishwasher. Check for kinks, bends, or clogs in the hose. Remove any visible blockages carefully. The air gap, usually located near the sink, prevents backflow. Clear debris from the air gap to ensure proper drainage. Proper hose and air gap function help prevent shutdowns during cycles.
Component Issues
Component issues often cause an LG dishwasher to keep turning off unexpectedly. These internal parts control key functions and ensure the appliance runs smoothly. When any component malfunctions, the dishwasher may stop mid-cycle or fail to complete its program.
Checking these components can help identify the root cause of the problem. Understanding how each part works will guide you in fixing the issue or deciding if professional help is needed.
Float Switch Malfunction
The float switch detects water levels inside the dishwasher. It prevents overfilling by stopping the water flow when the correct level is reached. If the float switch gets stuck or fails, it may cause the dishwasher to turn off suddenly. Dirt or debris can block the float, causing it to misread water levels. Cleaning or replacing the float switch often solves this problem.
Thermal Fuse Failure
The thermal fuse protects the dishwasher from overheating. It cuts power to the appliance if the temperature gets too high. A blown thermal fuse will stop the dishwasher from running altogether or cause it to shut down mid-cycle. Testing the fuse with a multimeter can confirm if it is faulty. Replacing a bad thermal fuse restores proper operation.
Control Board Problems
The control board acts as the dishwasher’s brain. It manages all electrical functions and cycle timing. A damaged control board can cause erratic behavior, including the dishwasher turning off by itself. Signs of control board issues include flickering lights or unresponsive buttons. Resetting or replacing the control board may be necessary to fix the problem.
When To Seek Help
Knowing when to seek help for your LG dishwasher is important. A dishwasher that keeps turning off can signal deeper problems. Early professional intervention can save time and money. Understanding the signs and common repairs helps you decide when to call a technician.
Signs You Need A Professional
The dishwasher stops frequently during cycles. It does not complete the washing process. Strange noises come from the machine. Water leaks around the door or base. The dishwasher does not turn on at all. Error codes appear on the display panel. The door latch feels loose or broken. There is a burning smell or sparks. These signs suggest a problem beyond simple fixes.
Common Repairs By Technicians
Technicians often replace faulty door latch assemblies. They fix or replace control boards causing power issues. Drain pump repairs are common to clear clogs. Power supply problems may require wiring checks. Heating element replacements restore proper drying. Sensors and switches might need calibration or replacement. Technicians also clean internal parts to improve function. These repairs usually restore dishwasher reliability and performance.
