Waking up to a load of wet laundry and an Lg Washing Machine dE1 Error flashing on the display can be a major inconvenience. This specific error code indicates that the washing machine’s main control board has detected that the door is not locked properly, preventing the cycle from starting or continuing. While it often points to a simple obstruction, it can also signal a failure in the electronic locking mechanism that requires a more technical approach to resolve.
This guide serves as a comprehensive resource for diagnosing and fixing the dE1 error, covering everything from basic resets to advanced hardware replacements.

What causes the LG washer dE1 error?
The dE1 error is distinct from a general “door open” error (often just “dE”) because it specifically relates to the locking mechanism’s failure to engage or signal that it is secure. In a Front Load Washer, the system requires a positive confirmation that the door is physically latched and electrically locked before it allows the drum to spin or fill with water.
The most common triggers for this error include:
- Physical Obstructions: Small items like socks or lint buildup preventing the door from closing fully.
- Misalignment: The door hinges may have sagged, causing the Striker Assembly (the hook on the door) to miss the latch opening.
- Faulty Components: The Door Lock Assembly or the internal Door Switch may have failed mechanically or electronically.
- Electrical Issues: Loose connections in the Wiring Harness or a malfunction in the Main Control Board.
Troubleshooting Guide: Step-by-Step Fixes
Before ordering replacement parts, follow this logical progression of troubleshooting steps. Most dE1 errors can be resolved without tools.
Step 1: Perform a hard reset
Electronic glitches are a frequent cause of false error codes. The Reset Procedure clears the machine’s short-term memory and can resolve the error if the sensor logic has simply frozen.
- Press the Power button to turn the washer off.
- Unplug the washing machine from the wall outlet or flip the circuit breaker.
- Press and hold the Start/Pause button for 5 to 10 seconds. This discharges any residual static electricity in the capacitors.
- Plug the washer back in and turn it on.
- Attempt to run a small “Rinse & Spin” cycle to see if the door locks successfully.
Step 2: Inspect the door alignment and striker assembly
If the reset does not work, the issue is likely physical. The Striker Assembly is the metal or plastic hook located on the door itself. When you close the door, this striker must insert perfectly into the lock assembly on the machine’s frame.

- Check for sagging: Open the door and lift it gently. If it moves upward significantly, the hinges may be loose. Tighten the hinge screws with a screwdriver.
- Inspect the striker: Look for cracks or damage on the striker hook. If it is bent, it will not engage the lock switch.
- Clear obstructions: Run your hand around the rubber door gasket. A small item like a coin or sock trapped in the fold can prevent the door from closing that final millimeter required to trigger the Door Sensor.
Pro Tip: For front load models, try closing the door by pushing firmly on the center-right side (where the handle is) rather than the top or bottom. If the error disappears, your door is slightly misaligned.

Step 3: Test the door lock assembly
The Door Lock Assembly is the most common part to fail when the dE1 error persists. This component contains a solenoid and a wax motor or magnetic switch that physically secures the door.
To inspect or replace this part:
- Safety First: Unplug the machine.
- Access: Open the door. You will see the lock mechanism mounted behind the front panel.
- Remove the Boot Seal: Use a flathead screwdriver to remove the spring clamp holding the gray rubber gasket (boot seal) to the front panel. Peel the gasket back to reveal the lock assembly.
- Remove Screws: Unscrew the two screws holding the lock assembly to the front of the washer.
- Inspect: Pull the assembly out through the hole. Check for burning smells, melted plastic, or clicking sounds when you manually simulate the striker entering it.
If the lock fails to click or looks damaged, it likely needs to be replaced.
Step 4: Check the wiring harness
Sometimes the lock is functional, but the signal never reaches the brain of the washer. The Wiring Harness connects the door lock assembly to the main control board.
- Vibration Damage: Washing machines vibrate intensely during the spin cycle. Over time, this can cause wires to chafe against the metal cabinet, exposing copper or severing the connection.
- Loose Plugs: Ensure the wire connector plugged into the door lock is seated firmly. Corroded terminals can also interrupt the low-voltage signal used by the Door Switch.
- Continuity Test: If you have a multimeter, you can check for continuity in the wires leading from the door lock to the control board. If a wire is broken, the harness needs repair or replacement.
Step 5: The main control board
If you have replaced the lock and checked the wiring, the issue may lie with the Main Control Board. This is the computer located (usually) at the back of the machine that controls all functions.
If the board has a “stuck relay,” it may think the door is open even when it is locked. Inspect the board for burn marks or swollen capacitors. Replacing the control board is a more expensive repair, so it should be the last resort after confirming the lock and wiring are sound.

Special note: Top load washers and the lid latch
While the dE1 error is predominantly associated with front loaders, it can occur on top load models as well. In this context, the entity to focus on is the Lid Latch.
Unlike front loaders, which use a heavy-duty locking solenoid, top loaders often use a lighter Lid Latch mechanism. The troubleshooting logic remains the same:
- Check if the magnetic magnet on the lid is missing (common on some older models).
- Inspect the slot where the latch enters the machine body for lint buildup.
- Listen for the “click” of the lid locking before the spin cycle. If it tries to click three times and fails, the Lid Latch sensor is likely defective.
Prevention and maintenance
To avoid recurring door errors:
- Do not slam the door. This damages the Striker Assembly and the internal plastic of the lock.
- Keep the seal clean. Regularly wipe down the door glass and rubber gasket to ensure a tight seal.
- Don’t Overload: stuffing the machine too full puts outward pressure on the door glass, straining the lock mechanism during the wash cycle.
By systematically checking these components—starting with a simple reset and moving toward the Door Lock Assembly and Wiring Harness—you can diagnose the “LG Washer dE1 Error” accurately. Most homeowners find that a simple realignment or a replacement of the inexpensive door latch restores their appliance to full working order without the need for a service call.

Frequently asked questions
What is the difference between a dE and a dE1 error code?
A general “dE” error typically indicates that the door is simply open. However, the dE1 error is more specific, signaling that the washing machine’s main control board cannot confirm that the door is successfully locked and secured, even if it appears to be closed.
How do I perform a hard reset to clear the dE1 error?
To perform a hard reset, power off the washer and unplug it from the wall. Press and hold the Start/Pause button for 5 to 10 seconds to discharge any remaining electricity. Plug the machine back in and run a “Rinse & Spin” cycle to see if the error has cleared.
Can a dE1 error be caused by how I load my laundry?
Yes. Overloading the machine can put outward pressure on the door glass, which strains the locking mechanism and may prevent it from engaging properly. Additionally, small items like socks or excess lint trapped in the rubber gasket can prevent the door from closing the final millimeter required to trigger the sensor.
What should I check if the door seems to be sagging?
If the door is misaligned, the striker assembly (the hook on the door) may miss the latch opening. Check the door hinges for loose screws and tighten them with a screwdriver. For front-load models, you can also try pushing firmly on the center-right side of the door near the handle to ensure the lock engages.
Is the dE1 error repairable on top-loading LG washers?
While more common on front loaders, the dE1 error can occur on top loaders. In these cases, it usually points to a faulty lid latch, a build-up of lint in the latch slot, or a missing magnet on the lid that signals the sensor to lock.
