# How to Fix LG Washing Machine Error dE (Door Error)
The LG washing machine error code **dE** (or sometimes **dE1** or **dE2**) indicates a problem with the door locking mechanism, meaning the machine cannot detect that the door is securely closed and latched.
When this error appears, the washer will typically stop mid-cycle or refuse to start the cycle altogether. Since the drum spins at very high speeds, the machine will not operate for safety reasons unless the door is confirmed to be locked.

## 1. Explanation: What This Code Means
| Code | Meaning (Plain English) | Likely Culprit |
| :— | :— | :— |
| **dE** | Door Error / Door Not Closed | Door Latch, Door Switch, or Control Board |
The most common cause for the dE error is a **faulty Door Latch Assembly** (which contains the Door Switch). This switch is responsible for telling the main control board whether the door is properly locked.

## 2. Step-by-Step Fix: How to Diagnose the dE Error
Follow these steps, starting with the simplest checks first.
### Step 1: Physical Door Check (Simple Fix)
The dE error can often be triggered by a simple physical obstruction or poor contact.
1. **Power Off:** Unplug the washer for 5 minutes and then plug it back in (this often clears temporary glitches).
2. **Examine the Door:** Open the door and check the rubber gasket (boot seal) just inside the opening. Look for any clothing (especially socks or small items) or debris caught in the seal area that might prevent the door from closing completely flush.
3. **Inspect the Latch:** Look at the plastic or metal “strike” plate on the door itself, and the latch mechanism built into the washer body. Ensure neither is damaged or misaligned.
4. **Re-close Firmly:** Close the door firmly, but do not slam it. You should hear a distinct *click* as the latch engages. Try wiggling the door after closing to ensure it is tight.
5. **Restart Cycle:** Attempt to start a new cycle. If the error persists, move to Step 2.
### Step 2: Test the Door Switch Assembly (Advanced Diagnosis)
If the door is closed properly but the error persists, the door lock assembly itself may be malfunctioning and needs replacement.
**Safety First:** Before performing any inspections inside the machine, unplug the washer from the wall outlet.
1. **Access the Switch:** The door switch is usually mounted on the front panel, directly behind the door opening.
* You will need to remove the two or three screws holding the switch in place (often accessible after peeling back the rubber door gasket slightly).
2. **Check for Continuity (Recommended Tool: Multimeter):**
* Disconnect the wiring harness from the latch assembly.
* Use a multimeter set to Ohms ($Omega$) to test the connectivity of the switch.
* When the latch is open (unlocked), you should read an open circuit (or very high resistance).
* When the latch is manually engaged (you can use a screwdriver to simulate the door closing into the lock mechanism), you should read continuity (near 0 Ohms).
* *If the switch shows no continuity when manually engaged, it is faulty and needs replacement.*
3. **Check for Visible Damage:** Look for burnt marks, corrosion, or broken plastic pieces inside the latch mechanism. Damage here confirms the need for replacement.
### Step 3: Check the Wiring
Sometimes the dE error is caused by loose or damaged wires leading from the door switch to the main control board.
1. **Inspect Connections:** Follow the wiring harness leading from the latch assembly back into the machine.
2. **Look for Pinches:** Ensure the wires haven’t been pinched, cut, or chewed (if you have rodents) or that the connectors are secure and free of rust or corrosion.
### Final Assessment
If you have confirmed that the door is closed and the wiring is sound, the **Door Lock Latch Assembly (Dryer Door Switch)** is the likely culprit and needs replacement. This is a common wear-and-tear item, as it cycles hundreds of times throughout the machine’s lifespan.
