The dE error code on an LG washer means the machine cannot confirm that the door is fully closed and locked. The washer refuses to start or pauses mid-cycle as a safety measure. Start by firmly closing the door — fabric caught in the seal is the most common cause and costs nothing to fix. If the door clicks shut but dE persists, the door latch or door lock assembly has likely failed and needs to be replaced.
What the dE Code Means
The LG washer dE error code is a door error. It appears when the control board sends power to the door lock motor and does not receive a confirmation signal back that the door has successfully latched and locked. The washer will not start a cycle — or will pause and halt a running cycle — until it detects a secure door.
LG uses sub-codes to identify the exact door fault on many models: dE1 indicates the door is not physically closed (latch not engaged), while dE2 points to a door lock switch or wiring fault even when the door appears closed. If your display shows a plain dE without a number, start with the physical checks below.
The safety logic is deliberate — a washer that runs with an unlatched door risks flooding the laundry room and injuring anyone who opens the door mid-spin. Never attempt to bypass or tape the door switch. If the physical checks don't resolve it, the door lock assembly needs replacement.
Common Causes — Most Likely First
How to Fix the dE Error — Step by Step
Inspect the door seal for trapped fabric
Run your fingers all the way around the rubber door gasket — both on the drum side and the door glass side. Look and feel for any clothing, lint buildup, or foreign objects that might be preventing the door from seating flush against the seal. Remove anything you find.
Close the door firmly until you hear a click
Push the door closed with a firm, deliberate push — not a pull or a gentle press. You should hear and feel a distinct click as the latch hook engages the lock receiver. If you do not hear the click, the door has not latched. Try pushing from the center of the door glass, not the edge.
Power-cycle the washer
Press Power to turn the machine off, wait 10 seconds, then press Power again. This clears the active dE flag so the control board re-checks the door status with fresh eyes. Then attempt to start a cycle normally. If it starts without displaying dE, the door is now properly latched.
Inspect the door latch hook for damage
Look at the plastic latch hook on the door itself — it is the small protruding hook or tab that inserts into the lock receiver on the machine body. If it is cracked, chipped, bent, or worn smooth, it will not engage the receiver properly. A damaged latch hook requires replacement of the door latch assembly, which is a straightforward part costing $10–$20.
Check the door lock receiver on the machine body
With the door open, look at the rectangular or oval slot on the washer body where the latch hook inserts. Press the small visible arm or paddle inside it with your finger — it should move freely and spring back. If it is stuck, cracked, or does not return, the door lock assembly needs to be replaced.
Check for door hinge sag
Open the door fully and look at the top and bottom hinges. The door should hang perfectly flat — if it droops noticeably at the outer edge, a worn hinge is pulling the latch hook out of alignment with the receiver. Replacing the door hinge corrects the alignment and allows the latch to engage again.
If dE persists after all physical checks — replace the door lock assembly
If the door seals cleanly, the latch hook looks intact, and the receiver moves freely but dE still appears, the electronic switch or wiring inside the door lock assembly has failed. This is a direct part swap — the door lock assembly unplugs from a wiring harness and bolts into the washer body. The part costs $15–$35; a technician can complete the replacement in under an hour.
When to Call a Technician
Most dE errors clear by removing trapped fabric and closing the door firmly. Book a professional LG washer repair if:
- dE appears every cycle even though the door closes with a clear click and no fabric is caught in the seal
- The display shows
dE2specifically — this indicates an electronic lock switch or wiring fault rather than a physical latching problem - The door will not open after a cycle ends and the machine is powered off — the lock assembly is stuck closed
- The latch hook or door hinge is visibly broken or bent and you are not comfortable replacing the part yourself
- dE appears alongside other codes such as LE or OE, suggesting the control board may be involved rather than just the door circuit

Frequently Asked Questions
What is the difference between dE, dE1, and dE2 on an LG washer?
All three are door errors, but they point to different parts of the door system. dE is a general door error — the control board cannot confirm the door is locked, but no specific sub-fault is identified. dE1 means the door is not physically closed — the latch hook has not engaged the receiver. dE2 means the door appears closed but the electronic switch inside the lock assembly is not confirming the locked state, pointing to a faulty switch or wiring connection. Start with the physical checks for any of these codes; if dE2 persists after the door closes cleanly, the lock assembly or wiring needs professional attention.
My LG washer door is closed and latched but still shows dE — what now?
If the door clicks shut firmly and dE still appears after a power-cycle reset, the door lock assembly has most likely failed electronically. The physical latch and the electronic switch are two separate components within the same assembly. The door can latch mechanically while the switch inside fails to send the confirmation signal to the control board. Replacing the door lock assembly resolves this in nearly all cases.
Can I run my LG washer with a dE error by holding the door closed?
No, and you should not try. The dE safety interlock exists to prevent the washer from running with an unsecured door. Even if you could hold the door closed manually, the control board will not start the cycle while it is receiving a dE signal. Attempting to bypass the door lock switch by taping or shorting it is dangerous and can void any remaining warranty.
My LG washer door won't open after the cycle — is this related to dE?
A door that won't open after a cycle is typically a stuck door lock assembly rather than the dE error itself, but it involves the same component. The door lock motor that was supposed to unlock the door after the cycle has jammed or failed in the closed position. Do not force the door — this can break the latch hook or crack the door glass. Unplug the washer for 10 minutes; this sometimes resets the lock mechanism. If the door remains stuck, a technician needs to manually release the lock and replace the assembly.
How long does a door lock assembly last on an LG washer?
A door lock assembly typically lasts 8–12 years with normal use. Machines used for large households doing multiple loads daily will wear the assembly faster. Signs that the assembly is nearing failure include the door feeling loose when closed, needing to push harder to get the click, or intermittent dE errors that clear on their own before becoming permanent.
Is the LG washer dE error covered under warranty?
LG's standard one-year limited warranty covers defects in materials and workmanship. A door lock assembly that fails within the first year due to a manufacturing defect should be covered. However, door errors caused by fabric caught in the seal, physical damage to the latch hook, or normal wear over time are generally not covered under warranty. Check your purchase date and contact LG directly if you believe the failure is a manufacturing defect.
