LG Washer Error Code DC2

DC2 on an LG washer indicates a door check error caused by a problem with the door lock switch unit. The washer detected that the door was not confirmed as locked after a door close operation, or the lock disengaged during a boil wash cycle due to internal pressure changes. The machine stops as a safety precaution to prevent operation with an unsecured door.

No, you should not attempt to run the washer while DC2 is active. The error indicates the door lock has not been confirmed, and running the machine without a secured door creates a risk of the door opening during the spin cycle or when the drum contains hot water. The washer's control system intentionally halts operation to protect both the user and the machine.

A reset may temporarily clear the DC2 code, but it will return if the underlying problem with the door lock switch unit or wiring has not been corrected. To reset, unplug the washer for a few minutes and then plug it back in. If DC2 reappears when you start a new cycle, proceed with inspecting and testing the door lock switch unit and its wiring harness.

Some causes of DC2 are DIY-friendly. Start by checking that the door is fully closed and that no laundry is caught in the door seal. Then inspect the wiring harness connected to the door lock switch unit for any loose or disconnected plugs. If the wiring looks intact and the door closes properly, the door lock switch unit itself likely needs to be replaced, which is a moderate-difficulty repair requiring disassembly of the front panel on most LG models.

If the fix is simply reseating a loose wiring connector, there may be no parts cost at all. If the door lock switch unit needs replacement, parts typically range from $20 to $75 depending on the specific LG model. Adding professional labor for diagnosis and installation, total repair costs generally fall in the range of $100 to $250.
