Seeing the DE error code on your LG washing machine? Don’t worry—this is a common and usually easy-to-fix issue. The DE error stands for “Door Error,” which means the washer isn’t able to detect that the door is securely closed. This article explains what’s causing the problem, how to fix it safely at home, and when it’s time to call a professional.

What does the DE error code mean?

When your LG washer shows the DE error, it’s indicating that the door isn’t locking properly. As a safety feature, the washer won’t start or continue a cycle unless the door is securely shut and locked.

Common causes of the DE error include:

• Door not fully closed or latched

• Obstruction between the door and the seal

• Worn or damaged door latch, hinge, or handle

• Faulty door lock mechanism

• In rare cases, a control board issue

Understanding the cause is the first step toward fixing the problem.

Before You Start: Safety First

Always unplug your washing machine before inspecting or touching any internal parts. Even though the DE error is usually mechanical, handling the door lock or latch area while the machine is powered on could pose a safety risk or trigger further errors. Also, make sure the floor around the washer is dry to avoid slipping or electric shock during troubleshooting.

Step-by-step troubleshooting

1. Try Manually Closing the Door

Gently but firmly push the door until you hear it click. If the door isn’t making full contact, the washer can’t lock it.

2. Check for Obstructions

Open the door and inspect the door seal (gasket) and surrounding area. Make sure no small clothing items, lint, or foreign objects are trapped between the door and the frame.

3. Inspect the Door Lock and Handle

• Look for visible damage or cracks in the latch, handle, or hinge.

• Wiggle the door gently to see if it feels loose or out of alignment.

• Clean the latch area with a soft cloth to remove any buildup that could prevent locking.

Sometimes, the door may appear closed but isn’t fully aligned with the lock. This can happen if the hinge is loose or slightly bent—often due to heavy slamming or long-term use. Open the door fully and gently lift it up to check for any sagging. If there’s noticeable movement or misalignment, a technician may need to realign or replace the hinge assembly.

If you’re comfortable with basic repairs, you can remove the washer’s top panel (usually two screws at the back) and inspect the door lock assembly from above. Look for any disconnected wires or burnt smells. However, do not attempt to open or repair the door lock unit itself—it’s a sealed electronic component.

4. Unplug and Reset the Washer

Sometimes the issue is caused by a minor software glitch:

• Unplug the washer for at least 1 minute.

• Plug it back in and restart the machine.

• Try running a short wash or spin cycle to see if the LG washer DE error clears.

Safety Tip: Never force the door closed or tamper with internal locks—this could cause more damage.

When to call a technician

If you’ve tried the steps above and the DE code keeps coming back, it may be time to seek professional help. Contact a certified LG appliance technician if:

• The door doesn’t click or stay closed when pushed

• The lock engages but the washer still won’t start

• You hear clicking but no response, or the control panel becomes unresponsive

• You suspect a faulty door lock assembly, wiring issue, or control board failure

A technician can test electrical connections, inspect the door sensor, and replace worn or faulty components safely.

Tips to prevent door errors in the future

• Close the door gently after each use—don’t slam it

• Avoid pulling or tugging the door mid-cycle

• Clean the gasket and latch area regularly to prevent lint and soap buildup

• Don’t overload the washer—heavy loads can push against the door and stress the locking mechanism

By following these habits, you can extend the life of your door lock and reduce the chance of future LG washer door errors.

Conclusion

The LG washer DE error means the door isn’t locking properly—often due to a small misalignment, obstruction, or latch issue. Most problems can be solved at home with basic steps like checking the seal, resetting the machine, or inspecting the latch. The average cost to fix an LG washer door lock issue ranges from $100 to $250, depending on your location and whether parts need to be replaced. Door lock assemblies themselves typically cost $40–$90, while labor makes up the rest. A certified technician can confirm whether it’s the lock, wiring, or control board and complete the repair safely under warranty. Many LG front-load washers include a child lock setting. Activating this mode prevents the door from being opened mid-cycle, which can reduce wear and tear on the latch mechanism. Check your user manual to see how to enable it—it’s usually done by holding a button combo for 3–5 seconds.

If those steps don’t fix the problem, don’t force it—call a technician to avoid damaging the washer and ensure it continues to work safely.
