The 3920DD3002D is the OEM LG dishwasher door packing — the rubber seal that runs around the dishwasher tub opening to create a watertight barrier when the door is closed. When this packing cracks, hardens, tears, or loses its shape, water escapes around the door during the wash cycle, causing leaks onto the floor. This is a genuine OEM part engineered to LG's original specifications for a guaranteed fit and leak-free seal.

✓ Model-Specific Repair Pages

The 3920DD3002D door packing fits a range of LG dishwasher models. The packing seats into a channel around the perimeter of the dishwasher tub and compresses against the door liner when the door is latched. Over time, heat and detergent exposure cause the rubber to harden and lose its sealing ability. Inspect the packing for cracks, tears, or deformation if your dishwasher is leaking from the door.

✓ Common Symptoms Fixed

Water leaking from the bottom of the dishwasher door during wash cycle. Puddles forming on the floor in front of the dishwasher. Water visible around the door seal during operation. Door packing cracked, torn, hardened, or deformed. Dishwasher not seating the door firmly against the tub.

✓ Installation Tips

Disconnect power to the dishwasher before servicing. The door packing seats into a channel around the perimeter of the tub opening — no tools are required for most LG models. Starting at one corner, pull the old packing out of the channel. Clean the channel with a damp cloth to remove any residue. Press the new packing firmly into the channel starting at the top center and working around both sides to the bottom. Close the door and check for even compression around the full perimeter. Run a short wash cycle and inspect for leaks.
