How to Fix dE Error on LG Washing Machine: Troubleshooting Tips
In this guide, we’ll explain the LG washing machine dE error code, what it means, its common causes, and how to fix it step-by-step.
The dE error on LG washing machines stands for Door Error. It means the washer is unable to detect that the door is properly closed and locked, so the machine will not start or continue the cycle for safety reasons.

How to Fix the dE Error on LG Washing Machines:
Common Door-related Error Codes:
| Error code | The Meaning: |
|---|---|
| dE | Door Lock Error |
| dE1 | Door Open Error: This dE1 error on the LG washing machine indicates that the washer has detected that the door is not properly closed or latched. |
| dE2 | Door Not Locked Error: This dE2 error occurs when the washer fails to lock the door securely. |
| dE4 | Door Open Fault: This dE4 error code suggests a problem with the door sensor or switch, preventing the washer from recognizing the door as closed. |
What Does the “dE” Error Mean?
The dE (door error) indicates the following:
- The washer door is not fully closed, or
- The door lock system is not engaging correctly
Because modern washers are safety-controlled, the cycle will not run unless the door is securely locked.
Common Causes of LG dE Error Code
- The door is not closed properly. This can happen if the door is not fully closed or if there is an obstruction preventing it from locking securely.

- Warped or misaligned door: If the door is warped or misaligned, it may not engage the door switch properly. This can lead to the dE error code.
- Inability to start: If the door hook on an LG washing machine is broken, it can result in an inability to start. The door latch is responsible for securing the washing machine door during operation, and if it’s damaged or malfunctioning, the machine may not initiate the cycle and display the dE (door error) code. This error code indicates that the door is not properly closed or the latch mechanism is faulty. Consequently, you won’t be able to use the washing machine until the door hook is replaced.

- Loose connection at the main board or door switch: A loose electrical connection between the main board and the door switch can trigger the “dE” error code.

- Bad door switch: If the door switch itself is faulty or damaged, it may not send the proper signal to the washer, resulting in the dE error code.
- Bad main board: In rare cases, a malfunctioning main board can cause the dE error code to appear. The main board is responsible for receiving signals from the door switch. If it fails to interpret these signals correctly, the error code can be triggered.
How to Fix LG Washer’s dE Error Code
- Double-check that the door is firmly closed and is not blocked by any objects.
- Ensure that the door is securely latched.
- Inspect the door for any signs of warping or misalignment. If you notice any abnormalities, consider realigning or replacing the door to ensure proper engagement with the door switch.
- Check the connections between the main board and the door switch. Make sure they are securely attached.
- Reconnecting or tightening the connections might resolve the issue.
- Inspect the door strike for any damage. The strike should align properly with the door lock.
- If there are alignment issues, adjust the strike or door to ensure proper alignment.
- If the above steps don’t resolve the issue, try the following: unplug the unit, close the door, and measure the resistance at the door lock. The resistance should read between 700 and 1500 ohms. If an open circuit is detected, it indicates a faulty door lock that needs replacement.

- Plug the unit back in and start the cycle. Listen for an audible “click” sound from the door lock. If no click is heard, check if a 120-Vac pulse can be measured from pin 2 to pin 4. If no voltage is present, it suggests a problem with the main board, and it may need to be replaced.
Final Thought
The LG washing machine dE error code is a door locking issue that prevents the machine from starting safely. In most cases, the problem is caused by an improperly closed door, trapped clothing, or a faulty door lock assembly.
