LG dryer error codes

Fill the steam feeder with tap water to the max line and confirm the drawer is closed.

Hold the model's Child Lock or Control Lock button combination for about 3 seconds.

Clean the lint screen, check the outside vent, and inspect the dryer duct before running another heated cycle.

Stop and verify the full vent path, especially the exterior hood and any crushed duct behind the dryer.

Do not keep restarting heated cycles. Clear or inspect the duct and exterior vent first.

Remove anything caught at the door, close it firmly, and inspect the latch for visible damage.

Check for a kinked, crushed, clogged, or frozen drain hose before another cycle.

Confirm the dryer is on the correct circuit and do not keep resetting a breaker that trips again.

Reset power once and restart the cycle only if the outlet and breaker look normal.

Power reset once; if it returns, the temperature sensing circuit likely needs service.
