What is this symptom?
Experiencing LG washing machine drain pump failure? Common symptoms include the OE error code, water remaining in the drum after cycles, or a humming pump that fails to remove water. These issues often stem from a clogged drain pump filter or an obstruction in the drain hose, which can prevent proper drainage.
