# How to Fix LG Error dE (Door Error)
The LG error code **dE** stands for **Door Error** or **Door Open**. This is one of the most common issues reported by LG washer owners.
The machine’s control board is signaling that it cannot confirm the door is securely closed and locked. For safety reasons, the machine will refuse to fill with water or spin until this connection is made. While the door may *look* closed, the electrical signal confirming the lock status is missing.
In 90% of cases, the problem lies with the **Door Lock Assembly** (also called the Door Interlock) failing to engage or communicate with the main control board.

## Step-by-Step Troubleshooting and Fix
Before assuming the part is broken, follow these steps sequentially, starting with the simplest fixes.
### Step 1: The Reset and Recalibration Check
Sometimes, the door sensor simply gets out of sync during a cycle interruption.
1. **Unplug the Machine:** Completely unplug the washer from the wall outlet or flip the circuit breaker.
2. **Wait:** Give it 5–10 minutes. This allows the main control board to fully discharge its electrical memory.
3. **Plug Back In:** Plug the machine back in, and firmly slam the door shut (do not be overly gentle).
4. **Test:** Try running a short cycle (like a rinse/spin). If the error persists, move to Step 2.
### Step 2: Check for Obstructions and Latch Alignment
A loose article of clothing, or debris in the latch area, is often enough to prevent the latch from fully engaging.
1. **Inspect the Latch:** Open the door and carefully inspect the latch hook (the piece attached to the door itself). Is it broken, bent, or obstructed?
2. **Inspect the Strike Plate (The Hole):** Look inside the hole where the latch goes (the Door Lock Assembly). Check for socks, coins, or bunched fabric that could be jamming the mechanism. Use a flashlight if needed.
3. **Verify Alignment:** Ensure the strike plate and the latch line up perfectly. If your machine has been moved recently, the door might have shifted slightly, causing misalignment.
### Step 3: Test the Handle and Release Mechanism
The door handle mechanism must allow the latch to properly connect with the electronic interlock switch.
1. **Handle Movement:** Gently pull the handle. Does it feel loose or unusually stiff? If the internal cable or lever connecting the handle to the lock mechanism is broken, the machine may never register the door as closed.
2. **Relieve Pressure:** If you stopped a cycle mid-wash, there might be pressure on the door. Try gently pushing *in* on the door before attempting to open it, and then close it again very firmly.
### Step 4: The Door Lock Assembly Failure (The Permanent Fix)
If Steps 1 through 3 fail, the problem is highly likely an internal electrical failure within the **Door Lock Assembly**. This component contains a solenoid and a micro-switch responsible for locking the door and signaling the control board. These switches wear out over time.
**Required Action:** Replace the Door Lock Assembly.
This is a DIY-friendly repair that requires basic tools (a screwdriver) and usually involves the following steps (consult your specific model’s service manual for precise instructions):
1. **Safety First:** **UNPLUG THE WASHER** from the power source.
2. **Access:** Remove the two or three screws securing the rubber door gasket clamp (usually a metal spring or wire clamp) just inside the door opening.
3. **Peel Back Gasket:** Gently pull the front of the rubber door gasket back into the drum. This exposes the Door Lock Assembly secured to the front panel.
4. **Unscrew/Disconnect:** Remove the two screws holding the assembly in place. Disconnect the wire harness plug from the old assembly.
5. **Install New Part:** Connect the wire harness to the new lock assembly, screw it back into the frame, and reinstall the door gasket and clamp.
