LG Washing Machine dE Error Code: Understanding Common Door-related Error Codes:

When it comes to LG washing machines, encountering dE error codes can be frustrating. Let’s explore the most common dE error codes and their meanings:

Error codeThe Meaning:
dEDoor Lock Error
dE1Door 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.
dE2Door Not Locked Error: This dE2 error occurs when the washer fails to lock the door securely.
dE4Door 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 is the reason for the dE error code appearing on my LG front-load or top-load washing machine?

The dE error code on LG front-load or top-load washing machines typically indicates a problem with the door switch. This error, which stands for “Door Lock Error,” occurs when the washer detects an issue with the door. Let’s explore the possible reasons behind this error:

  • 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 do or 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.

If the dE error on the LG washing machine is displayed, here are some troubleshooting steps to help resolve the issue:

  • 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.


It’s crucial to understand that when a dE error is displayed on the control panel of an LG front-load or top-load washer, the machine will not operate unless the door is securely locked. The dE error code itself serves as a safety feature, ensuring the proper functioning of the machine and preventing any accidental leaks or hazards during its operation.
