Common Reasons For Flashing Lights
Flashing lights on your LG dishwasher often signal an issue that needs attention. Understanding the common causes helps you address the problem quickly. These lights act as alerts for specific faults inside the machine. Ignoring them can lead to more serious damage or poor dishwasher performance.
Below are some common reasons why your LG dishwasher lights might be flashing.
Control Board Errors
The control board manages the dishwasher’s functions. Errors here can cause lights to flash continuously. Faulty wiring or a software glitch might trigger this issue. Resetting the dishwasher often clears minor errors. Persistent flashing may need professional repair or board replacement.
Door Latch Problems
The door latch ensures the dishwasher door stays closed during cycles. If the latch is broken or not aligned, lights will flash. The dishwasher may refuse to start if it thinks the door is open. Check the latch for damage or dirt. Cleaning or realigning the latch often solves the problem.
Power Supply Issues
Unstable or interrupted power can cause flashing lights. Loose plugs or faulty wiring in the home circuit affect performance. Power surges may also confuse the dishwasher’s control system. Ensure the dishwasher is plugged securely. If the problem continues, check your home’s electrical supply.
Performing A Hard Reset
Performing a hard reset on your LG dishwasher can often clear flashing light errors. This process helps reset the control board and can fix temporary glitches. It is a simple and effective troubleshooting step. Follow these easy instructions to perform a hard reset safely.
Power Off At Circuit Breaker
Locate the circuit breaker that controls your dishwasher. Flip the switch to the off position to cut power to the appliance. This step ensures the dishwasher is completely powered down. Do not just unplug the dishwasher; using the breaker is safer and more effective.
Waiting Period
After turning off the power, wait for at least one minute. This pause allows the dishwasher’s internal components to fully discharge. Waiting helps clear any temporary errors stored in the control board. Do not rush this step for best results.
Restoring Power
Flip the circuit breaker back to the on position to restore power. Your dishwasher will restart and the lights should reset. Observe if the flashing lights stop or if the dishwasher begins to work normally. If flashing continues, further troubleshooting may be needed.
Checking Door And Latch
Checking the door and latch on your LG dishwasher is a key step to fix flashing lights. The dishwasher will not start or work properly if the door does not close or latch correctly. Small problems like dirt or misalignment can cause the lights to flash. A careful check of the door and latch helps find and fix these issues fast.
Ensuring Door Is Fully Closed
Make sure the dishwasher door closes completely. Press the door firmly until you hear a click. This sound means the latch has caught and the door is secure. A door that is slightly open can cause the lights to flash. Do not force the door if it feels stuck. Check for anything blocking the door from closing all the way.
Inspecting Latch Assembly
Look closely at the latch assembly for damage or wear. Dirt or food bits can get stuck in the latch, stopping it from working well. Check if the latch moves freely when you open and close the door. A broken or bent latch must be replaced. A latch that does not lock properly often causes the flashing light error.
Cleaning Door Switch And Contacts
Clean the door switch and contacts gently with a dry cloth. Dust, dirt, or grease on these parts can block the electrical connection. This prevents the dishwasher from sensing the door is closed. Avoid using water or cleaning sprays. Make sure the contacts are dry before closing the door again. Clean contacts help the dishwasher work without flashing errors.
Interpreting Error Codes
Understanding the flashing lights on your LG dishwasher helps you identify problems quickly. The dishwasher uses blinking lights to signal different errors. Learning to interpret these codes can save time and prevent bigger issues. Each pattern of flashing lights points to a specific problem.
Reading the error codes correctly guides you to the right fix. Without this knowledge, it can be confusing to know what the dishwasher is trying to tell you. Below are key tips to help you decode these signals easily.
Blinking Patterns And Their Meanings
LG dishwashers flash their lights in certain patterns to indicate issues. For example, a slow blink might mean a minor error, while rapid blinking can signal a serious problem. Some common patterns include:
- One blink followed by a pause: Door latch is not secure.
- Two blinks repeated: Water supply problem.
- Three quick blinks: Drainage error.
- Continuous blinking: Control board malfunction.
Each blinking pattern corresponds to a specific error. Recognizing these patterns helps you decide the next steps. You can try basic troubleshooting or call a technician if needed.
Consulting The Owner’s Manual
The owner’s manual is the best place to find detailed error code information. It explains each blinking pattern clearly. Manuals often include diagrams and troubleshooting tips. This helps you fix small issues on your own.
Keep your manual handy for quick reference. If you lost it, you can download a copy from LG’s official website. Checking the manual first saves time and avoids unnecessary repairs.
Follow the manual’s instructions carefully. This ensures safe and correct handling of your dishwasher. Proper use and maintenance extend the appliance’s life and keep it running smoothly.
Inspecting Control Panel
The control panel is the brain of your LG dishwasher. It sends commands to start, stop, and run cycles. When flashing lights appear, the control panel might have issues. Inspecting it can help find the cause of the problem. Look closely at the buttons and touchpad. Small faults here can stop your dishwasher from working properly.
Unresponsive Buttons
Buttons that do not respond can signal control panel trouble. Dirt or moisture may block the button contacts. Press each button firmly and see if any feel stuck. Clean around the buttons with a soft cloth. Avoid using water directly on the panel. If buttons stay unresponsive, the control panel may need repair or replacement.
Touchpad And Board Issues
The touchpad controls many dishwasher functions. Faulty touchpads cause flashing lights or error codes. Inspect the touchpad for cracks or damage. Sometimes, the circuit board behind it can fail. Look for burn marks or loose wires. Resetting the dishwasher may clear minor glitches. Persistent issues often require a professional to test the control board’s electronics.

When To Seek Professional Help
Knowing when to seek professional help for your LG dishwasher is important. Some issues with flashing lights need expert diagnosis. Avoid wasting time on fixes that don’t work. A technician can find and solve complex problems safely and quickly.
Persistent Flashing After Resets
If the flashing lights continue after multiple resets, it signals a deeper problem. Simple power cycling may not clear errors from the control board. Repeated flashing often means a fault in the system that requires technical attention. Do not ignore ongoing blinking; it may worsen over time.
Potential Component Failures
Flashing lights can indicate failing parts inside the dishwasher. Common components that fail include the door latch, control board, or sensors. These parts affect the machine’s operation and safety. A professional can test each component with proper tools. Replacing or repairing parts yourself may cause further damage.
Finding A Qualified Technician
Choose a technician with LG dishwasher experience for accurate repairs. Certified professionals understand LG error codes and flashing light signals. Local appliance repair services often offer quick and reliable support. Verify credentials and customer reviews before hiring. Proper repairs extend your dishwasher’s lifespan and ensure safety.
Preventive Maintenance Tips
Preventive maintenance keeps your LG dishwasher running smoothly and avoids flashing light issues. Simple care steps reduce wear and tear. Regular upkeep improves performance and extends the appliance’s life.
Regular Cleaning
Clean the dishwasher interior often to prevent buildup. Remove food particles from filters and spray arms. Wipe door seals and edges to stop mold and grime. Use a dishwasher cleaner monthly for deep cleaning. Clean parts work better and reduce error signals.
Proper Door Handling
Always close the door gently but firmly. Make sure the latch secures well each time. Avoid slamming or forcing the door open. Check for debris that blocks the latch. A well-closed door stops flashing light problems linked to door errors.
Routine System Checks
Check the dishwasher’s control panel regularly for error codes. Listen for unusual sounds during cycles. Inspect hoses and connections for leaks or damage. Test the power supply and reset the machine as needed. Early checks catch small problems before lights start flashing.
