If your appliance display is flashing the Lg Washing Machine De Error, it indicates that the system cannot detect that the door or lid is securely locked. This safety feature prevents the machine from operating when the door is open, but it can interrupt your laundry routine when triggered falsely.
Understanding the dE error code
The “dE” code stands for “Door Error.” In simple terms, the washing machine’s main PCB (Printed Circuit Board) has not received the “locked” signal from the door mechanism. Without this confirmation, the control board will not allow the drum to fill with water or spin.

While this often points to a simple obstruction, it can also indicate a failure in mechanical components like the door lock assembly or electrical issues within the wiring harness. Diagnosing the problem varies slightly depending on whether you own a front load washer or a top load washer.
Common causes and preliminary checks
Before dismantling your machine, perform these initial inspections to rule out non-technical issues.

1. Check for obstructions and alignment
The most frequent cause is a physical obstruction. Clothes can easily get trapped between the door glass and the door seal gasket.
- Inspect the Gasket: Run your hand around the rubber seal to ensure no small items (like socks) are preventing the door from closing fully.
- Check the Door Strike: The door strike is the small hook or tab on the door that slides into the lock mechanism. Ensure it is not bent, loose, or misaligned.
2. Perform an error code reset
Electronic glitches can sometimes trigger false positives.
- Unplug the washing machine from the power outlet.
- Press and hold the “Start/Pause” button for 5 seconds to dissipate any residual static electricity.
- Wait for 3 to 5 minutes.
- Plug the machine back in and attempt to start a cycle.
Fixing the Lg washing machine DE error on top load models
Top loaders use slightly different mechanisms than front loaders. The error is often related to the lid switch or magnetic detection system.

Inspecting the magnetic sensor
Many modern LG top loaders use a magnet embedded in the lid and a magnetic sensor (Hall sensor) in the cabinet to detect closure.
- Locate the Magnet: Check the front edge of the lid. If the magnet has fallen out or is rusted, the sensor will not trigger.
- Test with a Spare Magnet: You can place a small refrigerator magnet over the sensor area on the bezel while the machine is on. If the error disappears, the lid magnet is the issue.
Checking the lid switch
Older top load models may use a physical mechanical lid switch. If the plastic tab on the lid is broken, it will not depress the switch inside the lock assembly. Visually inspect the lid strike for damage.

Troubleshooting front load washers
For a front load washer, the issue is almost always mechanical and related to the locking assembly located inside the front panel.
Replacing the door lock assembly
If the door clicks but the error persists, the door lock assembly usually has a failed internal solenoid or PTC (Positive Temperature Coefficient) switch.
- Access the Lock: Open the door and locate the door latch area.
- Remove the Seal Clamp: Use a flathead screwdriver to remove the spring clamp holding the door seal gasket in place around the lock.
- Unscrew the Assembly: Remove the two screws holding the lock assembly to the front panel.
- Disconnect Wires: Reach inside, pull the assembly out, and disconnect the wiring harness.
- Install New Part: Connect the new lock, secure it, and reattach the seal.
Wiring and control board issues
If replacing the lock does not fix the Lg Washing Machine De Error, the issue may lie deeper in the electrical system.
- Inspect the Wiring Harness: Vibrations during the spin cycle can cause wires to chafe or disconnect. Check the continuity of the wires running from the door lock to the control board.
- Main PCB Failure: If the harness and lock are functional, the main PCB may be failing to send the voltage required to lock the door. Look for burn marks or swollen capacitors on the board. This is a complex repair that typically requires a professional technician.
Summary of fixes
| Component | Symptom | Solution |
|---|---|---|
| Door Seal Gasket | Door won’t close flush | Remove trapped laundry; clean the seal. |
| Door Strike | Wobbly or bent hook | Tighten screws or replace the strike. |
| Door Lock Assembly | Door closes but won’t click/lock | Replace the assembly. |
| Control Board | New lock installed, error persists | Inspect PCB for damage. |
By systematically checking the door latch, alignment, and electrical connections, you can resolve the Lg Washing Machine De Error and return your appliance to full functionality. Always ensure the machine is unplugged before touching internal components to ensure safety.
Frequently asked questions
What exactly does the dE error code mean on an LG washer?
The “dE” code stands for Door Error. It signifies that the washing machine’s main control board (PCB) cannot confirm that the door or lid is securely closed and locked. For safety reasons, the machine will not fill with water or begin a cycle until this signal is received.
How do I perform a hard reset to clear a temporary dE error?
To reset the electronics, unplug the washing machine from the power outlet. Press and hold the “Start/Pause” button for approximately 5 seconds to drain any residual power. Wait 3 to 5 minutes before plugging the unit back in and attempting to start a fresh cycle.
Can a top-load washer have a dE error even if the lid is physically closed?
Yes. In many top-load models, the machine uses a magnet in the lid and a sensor in the frame to detect closure. If the magnet has fallen out, rusted, or shifted, the sensor won’t trigger. You can test this by placing a small refrigerator magnet over the sensor area to see if the error disappears.
What is the most common mechanical cause for this error in front-load washers?
The most common cause is a faulty door lock assembly. Over time, the internal solenoid or switch inside the locking mechanism can fail. Other frequent issues include laundry getting caught in the rubber door seal gasket or a misaligned door strike that prevents the latch from clicking into place.
What should I do if replacing the door lock doesn’t fix the dE error?
If a new lock assembly does not resolve the issue, the problem is likely electrical. You should inspect the wiring harness for any loose or damaged wires caused by machine vibrations. If the wiring is intact, the main PCB (control board) may be damaged and unable to process the locking signal, which typically requires a professional repair.
