Modern LG washing machines are built with smart diagnostic systems that help homeowners identify problems quickly. Instead of guessing what’s wrong when your washer suddenly stops mid-cycle, LG washer error codes give clues that point directly to the root of the issue. Understanding these codes can save time, reduce repair costs, and help you decide whether the problem is easy to fix at home or requires professional assistance.
This guide explains the most common LG washer error codes, what they mean, and how to troubleshoot them safely. The explanations are written in simple, easy-to-understand language so anyone can use this guide—even without technical experience.
Why LG Washers Display Error Codes
LG washers use sensors to monitor water levels, temperature, drum rotation, motor performance, and internal electronics. When something goes wrong, the machine displays a code to prevent damage. These codes help you:
- Identify the exact issue
- Prevent further damage to the washer
- Decide whether a DIY fix is possible
- Save money on unnecessary technician visits
Most issues can be resolved with basic tools or simple adjustments—like checking hoses or cleaning filters. More serious codes, especially those related to motors or control boards, may need professional repair.
Common LG Washer Error Codes and How to Fix Them
Below are the most frequently seen LG washer error codes and the step-by-step methods for diagnosing and fixing each one.
- OE Error Code – Drain Error
Meaning:
The washer is not draining water properly.
Common Causes:
- Clogged or kinked drain hose
- Blocked drain pump filter
- Faulty drain pump
- Sewer line blockage
How to Fix:
- Turn off and unplug the washer.
- Check the drain hose behind the machine. Make sure it’s not twisted or blocked.
- Remove the drain pump filter, usually located at the bottom front behind a small panel. Clean out lint, debris, coins, or hair.
- Restart the washer to see if the issue is resolved.
- If the pump makes loud noises or still won’t drain, the pump may need replacement.
- IE Error Code – Water Inlet Error
Meaning:
The washing machine is not filling with water fast enough.
Common Causes:
- Closed or partially closed water supply valves
- Low household water pressure
- Clogged inlet filters
- Faulty water inlet valve
How to Fix:
- Ensure both hot and cold water supply valves are fully open.
- Check hoses for kinks or blockages.
- Turn off water supply and clean the small inlet screens inside the hose connection points.
- If water pressure in your house is low, the washer may struggle to fill.
- If none of the above works, the inlet valve may need replacement.
- LE Error Code – Motor Locked
Meaning:
The motor is overloaded or unable to turn the drum.
Common Causes:
- Overloaded drum
- Too many heavy items (e.g., rugs, blankets)
- A worn rotor or stator
- Faulty hall sensor
- Wiring issues around the motor
How to Fix:
- Power off the washer.
- Remove excess laundry from the drum.
- Try running the cycle again with fewer items.
- If the code returns, the motor system may need to be inspected by a technician.
- UE Error Code – Unbalanced Load
Meaning:
The washer cannot spin because the load is uneven.
Common Causes:
- Heavy items grouped on one side
- Too few items in the drum
- Bedding or towels that absorb unevenly
How to Fix:
- Pause the cycle.
- Open the door and redistribute the clothes evenly.
- Add a few lighter items if you only washed one heavy piece.
- Restart the spin cycle.
This code is one of the easiest to fix and requires no tools.
- FE Error Code – Overflow Error
Meaning:
The washer is overfilling with water.
Common Causes:
- Faulty water inlet valve stuck open
- Pressure sensor malfunction
- Blocked air tube to the pressure sensor
How to Fix:
- Turn off the washer immediately.
- Shut off the water supply valves.
- Restart the washer to reset the electronics.
- If water continues to enter the machine even when powered off, the inlet valve must be replaced.
- If the washer does not sense water level correctly, the pressure sensor needs inspection.
- PE Error Code – Water Level Sensor Error
Meaning:
The washer is having trouble reading the water level.
Common Causes:
- Defective pressure switch
- Clogged pressure hose
- Loose wiring connection
How to Fix:
- Unplug the machine.
- Locate the pressure hose (usually near the drum) and check for blockages.
- Inspect the hose for cracks or kinks.
- If the hose is fine, the pressure switch or wiring may need professional service.
- tE Error Code – Thermistor / Temperature Sensor Error
Meaning:
The water temperature sensor is not functioning properly.
Common Causes:
- Faulty thermistor
- Damaged wiring
- Heating element issues (in machines with internal heaters)
How to Fix:
- Turn off the washer for 10 minutes to reset the electronics.
- Restart the cycle.
- If the code returns, a technician may need to replace the thermistor.
- dE Error Code – Door Error
Meaning:
The door is not locking properly.
Common Causes:
- Door not fully closed
- Broken door latch
- Faulty door lock sensor
- Obstruction preventing proper closure
How to Fix:
- Open the door and ensure no clothing is trapped.
- Firmly close the door and restart the cycle.
- Inspect the latch for physical damage.
- If the door still won’t lock, the lock mechanism may need replacing.
- CE Error Code – Overcurrent in Motor
Meaning:
The motor is drawing too much electrical current.
Common Causes:
- Overloaded drum
- Motor failure
- Control board issues
How to Fix:
- Remove some clothes and try again.
- If the code returns, unplug the washer for 10 minutes.
- If still unresolved, the motor or control board needs technician service.
- CL Code – Child Lock Activated
Meaning:
Buttons are locked to prevent accidental use.
How to Fix:
- Press and hold the Child Lock button combination (usually marked on the panel) for 3–5 seconds.
- The machine should beep and unlock.
This is not an error, but many users mistake it for one.
General Troubleshooting Tips for LG Washers
Aside from specific error codes, here are helpful practices to avoid most washer problems.
1. Clean the Drain Pump Filter Regularly
Lint, coins, and hair can clog the filter, causing OE errors. Cleaning it monthly helps prevent draining problems.
2. Avoid Overloading the Drum
Heavy loads strain the motor and suspension system. Fill the drum loosely to extend the washer’s lifespan.
3. Use the Right Detergent
LG washers require high-efficiency (HE) detergent. Using the wrong type causes excessive suds and sensor issues.
4. Level the Washer
A shaking washer causes UE errors. Make sure all legs touch the floor evenly.
5. Check Hoses Annually
Replace hoses that show signs of bulging, cracking, or leaks.
When to Call a Professional
While many error codes can be fixed at home, certain signs indicate it’s time to call a technician:
- Burning smell
- Repeated motor-related errors
- Electrical sparks
- Water leaking from the bottom
- Control panel not responding
- Drum not turning at all
Attempting to repair electrical components without experience can be dangerous.
Final Thoughts
LG washer error codes are designed to protect your machine and guide you toward the right fix. With a little understanding, most common issues—such as drainage problems, unbalanced loads, or water supply errors—can be solved quickly and safely at home. Regular maintenance, proper loading, and using the correct detergent will help keep your washer running smoothly for years.
By learning to interpret these error codes, you gain confidence, save money on unnecessary repairs, and extend the lifespan of your appliance.
