LG Washer Error Code drn

The drn code on an LG washer means the machine failed to drain water within the allotted time during a cycle. The control board detected that water remained in the drum when it should have been fully evacuated. This fault points to the drain hose, the pump filter, or the drain pump itself as the source of the problem.

It is not advisable to continue running the washer while the drn code is active. The machine will not complete its cycle properly, and water left sitting in the drum can promote mold and mildew growth. Continuing to force cycles without resolving the drainage issue can also put additional strain on the drain pump motor.

Resetting the washer may temporarily clear the drn code, but the error will return if the underlying drainage problem has not been resolved. A reset is useful for confirming whether the code was triggered by a one-time condition, such as a temporary kink in the hose, but it is not a fix on its own. The drain system should be inspected and corrected before running another full cycle.

Start by checking the drain hose at the back of the machine for any kinks, bends, or tight folds and straighten them out. Next, locate and clean the drain pump filter, which is typically behind a small access panel at the lower front of the washer. If both are clear, check that the household standpipe is not clogged. If the problem persists after these steps, the drain pump may need to be tested and potentially replaced.

If the fix is simply clearing a kinked hose or cleaning the pump filter, there is no parts cost involved. If the drain pump motor has failed, replacement pump parts typically range from $30 to $100 depending on the model. Adding professional labor, the total repair cost generally falls between $100 and $250.
