LG Washer Error Code dE3

The dE3 code means the washer detected an open or unsecured lid during the spin check step called t9. The machine performs this safety check before allowing the drum to spin, and if the lid sensor does not confirm a closed lid at that point, the cycle is halted. The issue can be as simple as a lid that was opened during the cycle, or it may point to a faulty magnet, sensor, or wiring.

A reset may temporarily clear the dE3 code, but if the underlying cause is a faulty sensor, a misaligned magnet, or a damaged latch, the error will return when the machine reaches the spin check step. To reset, unplug the washer for one to two minutes, then plug it back in. A reset is only a lasting solution if the lid was simply open or unlatched when the code was triggered.

If only the lid magnet or sensor needs replacement, parts typically cost in the range of $10 to $50 depending on the specific component. If a service technician is needed for diagnosis and labor, total repair costs generally fall in the range of $100 to $200. A damaged wiring harness or a failed control board would push costs higher, though control board failure is an uncommon cause of this specific error.

Start by firmly closing the lid until it latches, then restart the cycle to see if the error clears. If it returns, inspect the lid magnet and the sensor on the machine body for misalignment or damage. Check the wiring harness for loose connectors or broken wires. If the sensor or magnet is confirmed faulty through testing, the defective component will need to be replaced.

The washer will not allow the spin cycle to proceed while the dE3 error is active, which is the intended safety behavior. Do not attempt to bypass the lid sensor or interlock system. Spinning with an unsecured lid is a safety hazard, and the machine is designed to prevent this. Diagnose and resolve the root cause before continuing to use the appliance.
