If you have encountered the Lg Washing Machine dE2 Error on your display, it indicates that the appliance believes the door is closed but the locking mechanism has failed to engage properly. This common fault prevents the wash cycle from starting as a safety precaution, ensuring the machine does not operate with an unsecured door. While it can be frustrating, this error code often points to specific mechanical or electrical issues that can be diagnosed and resolved with a systematic approach.
Understanding the LG washer dE2 error code
The DE2 code specifically stands for “Door Error,” implying that the main control board is not receiving the correct signal from the door switch sensor. Unlike a simple “door open” error, this code usually means the door is physically shut, but the bolt or hook inside the lock assembly hasn’t fully extended or latched.
For a front-load washer, this system relies on a precision-aligned door latch strike and an electronic lock assembly. If you own a top-loading model, a similar mechanism involves the lid lock. In both cases, if the computer cannot verify that the unit is safely locked, it will trigger the DE2 alert and halt operation.
Common causes of the Lg washing machine dE2 error
Several factors can trigger this specific error code, ranging from minor obstructions to component failure.
1. Obstructions and misalignment
The most frequent cause is a physical obstruction. Small items like socks or accumulated lint can get trapped between the door glass and the rubber gasket, preventing the door from closing fully. Additionally, if the door latch strike—the plastic or metal hook on the door itself—is slightly bent or misaligned, it will not slide correctly into the lock assembly.
2. Faulty door lock assembly
The door lock assembly is an electrical component that secures the door during the cycle. Over time, the internal solenoid or wax motor can fail, or the plastic housing can crack. If this part malfunctions, it cannot send the “locked” signal to the control board, resulting in the error.
3. Wiring and control board issues
In rarer cases, the issue lies deeper in the machine’s electronics. The wiring harness connecting the door lock to the main control board may become loose or damaged due to the machine’s vibration. If the wiring is intact, the main control board itself might be suffering from a glitch or a blown component, failing to interpret the sensor data correctly.

How to fix LG washing machine dE2 error
Before ordering replacement parts or calling a professional, follow these steps to isolate the problem.
Step 1: Perform a hard reset
A simple electronic glitch can sometimes cause false error codes.

- Turn off the washer and unplug it from the power outlet.
- Press and hold the “Start/Pause” button for 5 seconds to dissipate residual power.
- Wait for 5 minutes before plugging the machine back in.
- Attempt to run a small cycle to see if the error clears.
This reset procedure often resolves temporary communication failures between the control board and the sensors.
Step 2: Check for obstructions and alignment
Inspect the door area carefully.
- Wipe down the door seal and glass.
- Check the door latch strike for any signs of damage or looseness. Tighten the screws if necessary.
- Close the door firmly. Sometimes, a gentle push on the handle area while the cycle starts can help the latch engage.
Step 3: Use LG smart diagnosis
Modern LG appliances are equipped with LG Smart Diagnosis technology. This feature allows your washer to communicate directly with the LG ThinQ app on your smartphone.
- Open the app and select your washer.
- Follow the prompts to run a diagnosis.
- The app can provide a more detailed analysis of the DE2 error, confirming if the door switch sensor is the culprit.
Repair and component replacement
If the basic troubleshooting steps do not resolve the issue, hardware replacement may be necessary.
Replacing the door lock assembly
For a DIY-savvy homeowner, replacing the door lock assembly is a moderate repair.
- Unplug the washer.
- Remove the spring clamp holding the door boot seal to access the lock mechanism.
- Unscrew the lock assembly from the front panel.
- Disconnect the wiring harness and install the new part.
Always ensure you purchase OEM replacement parts specific to your model number to guarantee compatibility.
Inspecting internal components
If a new lock does not fix the problem, inspect the wiring harness for continuity using a multimeter. Breaks in the wire can prevent the signal from reaching the main control board. If the wiring tests fine, the control board itself may need replacement, which is a more complex and expensive repair.
When to call a professional
Working with high-voltage appliances carries risks. If you are uncomfortable handling electrical components, or if the diagnosis points to a main control board failure, it is advisable to contact a certified appliance repair technician. They have the tools to safely test the lid lock or door switch sensors and can ensure the repair is performed according to safety standards.
By understanding the mechanics behind the Lg Washing Machine dE2 Error, you can determine whether a quick reset will suffice or if a part replacement is required to get your laundry routine back on track.
Frequently asked questions
What exactly does the LG DE2 error code mean?
The DE2 error indicates a “Door Error.” It occurs when the washing machine’s control board perceives that the door is closed but cannot confirm that the locking mechanism has successfully engaged. For safety reasons, the machine will not begin a wash cycle until the door is securely locked.

How do I perform a hard reset to clear the DE2 error?
To perform a hard reset, turn off the washer and unplug it from the wall. Press and hold the “Start/Pause” button for five seconds to dissipate any residual electricity. Wait about five minutes before plugging the unit back in and attempting to run a new cycle.
Can a physical obstruction cause this error even if the door looks closed?
Yes. Small items like socks, threads, or accumulated lint can get caught between the door glass and the rubber gasket. Even if the door appears shut, these obstructions can prevent the door latch strike from aligning perfectly with the lock assembly, triggering the DE2 code.
What should I do if the hard reset does not fix the problem?
If a reset fails, you should inspect the door latch strike for damage and ensure it is tightened properly. You can also use the LG Smart Diagnosis feature via the ThinQ app to get a detailed analysis. If the hardware is faulty, you may need to replace the door lock assembly or contact a professional technician to inspect the internal wiring and control board.
