LG Washer Error Codes

LG washers are engineered for efficiency and durability, but error codes may occasionally appear due to operational issues. Understanding these codes can help you diagnose and resolve problems quickly. In some cases, replacing essential LG Washer Parts may be necessary to restore peak performance. Below is a comprehensive guide to common LG washer error codes, their possible causes, and effective troubleshooting solutions.

1. Error Code IE - Water Inlet Error

Issue: The correct water level is not reached within 8 minutes, or the preset level is not reached within 20 minutes.

Possible Causes & Solutions:

• Check if the water supply valve is fully open.

• Inspect the inlet hose for kinks or blockages.

• If the issue persists, the inlet valve may need replacement.

2. Error Code UE - Unbalanced Error

Issue: The load is unbalanced, causing instability.

Possible Causes & Solutions:

• Ensure laundry is evenly distributed in the drum.

• Avoid overloading or underloading the machine.

• Place the appliance on a flat, stable surface to prevent tilting.

3. Error Code 0E - Drain Error

Issue: Water is overflowing, and the drain pump activates to remove excess water.

Possible Causes & Solutions:

• Check if the drain hose is clogged or kinked.

• Inspect the drain pump for blockages.

• Clean the filter to ensure proper water flow.

4. Error Code FE - Overflow Error

Issue: Water is overflowing beyond the safe limit.

Possible Causes & Solutions:

• The water inlet valve may be malfunctioning; inspect and replace if necessary.

• A faulty water level sensor may be misreading the water level and require replacement.

5. Error Code PE - Pressure Sensor Error

Issue: The pressure sensor assembly is malfunctioning, leading to incorrect water level readings.

Possible Causes & Solutions:

• Inspect and clean the pressure sensor hose for blockages.

• If the error persists, replace the pressure sensor assembly.

6. Error Code dE1, dE2 - Door Open Error

Issue: The door is not fully closed, or the door switch is malfunctioning.

Possible Causes & Solutions:

• Ensure the door is securely shut before starting a cycle.

• Check for loose electrical connections at the door switch and control board.

• Replace the door switch assembly if necessary.

7. Error Code tE - Heating Error

Issue: The thermistor is defective, preventing proper temperature regulation.

Possible Causes & Solutions:

• Inspect the thermistor for damage or disconnection.

• Replace the thermistor if faulty.

8. Error Code LE - Locked Motor Error

Issue: The motor harness connections are loose or disconnected, causing the motor to lock.

Possible Causes & Solutions:

• Ensure the motor harness connectors are properly attached.

• Check for damaged wiring between the stator assembly and control board.

• Replace the motor harness if necessary.

9. Error Code EE - EEPROM Error

Issue: The EEPROM is malfunctioning, causing system errors.

Possible Causes & Solutions:

• This error occurs during the Load Test Mode. Restart the appliance and attempt a reset.

• If the issue persists, the control board may need replacement.

10. Error Code PF - Power Failure

Issue: A sudden power failure occurred during operation.

Possible Causes & Solutions:

• Ensure the power cord is securely plugged in.

• Check the circuit breaker for any tripped switches.

• Restart the appliance and resume operation.

11. Error Cod Sud - Suds Error 

Issue: The washing machine detects excessive suds and activates a Suds Reducing cycle, adding about two hours to the cycle time. If suds persist during spinning, the machine stops to prevent leaks. 

Possible Causes & Solutions:

• Using too much detergent. Try reducing the amount of detergent.

• Use only high-efficiency (HE) detergent.

• Run an extra rinse cycle to remove excess suds.

12. Error Code uS - Vibration Sensor Error 

Issue: The vibration sensor has malfunctioned.

Possible Causes & Solutions:

• Restart the washer to reset the sensor.

• Ensure the washer is on a level surface.

• If the error persists, contact LG support for sensor replacement.

13. Error Code Ed1 - Breakdown Detergent Pump 

Issue: The detergent in the reservoir did not decrease, possibly due to hardened detergent. 

Possible Causes & Solutions:

• Regularly check and clean the detergent reservoir.

• Use liquid detergent to prevent hardening.

• If the pump is faulty, consider replacing it.

14. Error Code Ed2 - Open Circuit Pump 

Issue: The liquid detergent level did not change.

Possible Causes & Solutions:

• Inspect the pump for blockages.

• Ensure the detergent reservoir is not clogged.

• If needed, replace the detergent pump.

15. Error Code Ed3 - Breakdown Softener Pump 

Issue: The fabric softener in the reservoir did not decrease, likely due to hardened softener.

Possible Causes & Solutions:

• Clean the softener reservoir regularly.

• Use liquid fabric softener to prevent clogging.

• Check for pump functionality and replace if necessary.

16. Error Code Ed4 - Open Circuit Softener Pump 

Issue: The fabric softener level remained unchanged.

Possible Causes & Solutions:

• Inspect and clean the softener reservoir.

• Ensure the pump is working correctly.

• Replace the softener pump if required.

17. Error Code Ed5 - Communication Defect 

Issue: Poor communication with the PCB (Printed Circuit Board) causes the washer to malfunction.

Possible Causes & Solutions:

• Restart the appliance.

• Check wiring connections between the PCB and control board.

• Contact LG support for a PCB inspection or replacement.

18. Error Code OPn - Drawer Open 

Issue: The washer was started without fully closing the detergent drawer or was opened during operation.

Possible Causes & Solutions:

• Ensure the drawer is completely closed before starting the cycle.

• If the drawer sensor is faulty, consider a replacement.

19. Error Code 0E - Drain Error 

Issue: The machine fails to drain properly due to an imbalance or obstruction.

Possible Causes & Solutions:

• Make sure the load is balanced.

• Check if the appliance is tilted and adjust it.

• Avoid placing non-distributable items in the drum.

• Clean the drain pump filter and hose for blockages.

20. Error Code IE - Water Inlet Error

Issue: The washer does not reach the correct water level within the required time.
