LG Washer Error Code dL

The dL code on an LG washer indicates a door fault detected while the machine is running. It means the control board received a signal that the door was open, improperly latched, or not correctly communicating its locked state. Causes include a physically opened door, pressure buildup during high-temperature cycles, faulty door lock switch terminals, damaged wiring, or a main PCB issue.

No, you should not continue running the washer while the dL code is active. The machine stops operation as a safety measure because an unsecured door during a wash cycle can result in water leaking out of the drum. Resolve the door issue before resuming use.

Costs vary depending on the cause. If only a loose wiring connection is involved, repair costs may be minimal, primarily covering a service call in the range of $75 to $150. Replacing the door lock switch assembly typically adds $20 to $80 in parts. A main PCB replacement is the most expensive outcome, with parts and labor potentially ranging from $200 to $400 or more depending on the model and service provider.

In many cases, yes. Start by making sure the door is fully closed and latched, then restart the cycle. If the error returns, inspect the wiring harness and connector terminals at the door lock assembly for loose connections, corrosion, or damaged insulation. If you are comfortable checking 220V wiring safely, these inspections are within the reach of a knowledgeable DIYer. However, if the door lock switch itself needs replacement or the main PCB is involved, a technician with proper tools may be needed.

A reset may temporarily clear the display, but the code will return if the underlying problem is not fixed. If the door was simply opened accidentally during a cycle, closing it securely and restarting should resolve the error. If a wiring fault, faulty lock switch terminal, or PCB issue is the root cause, the dL code will reappear once the machine attempts to operate again.
