The MDS65210409 is the current genuine OEM door seal gasket for select LG dishwashers, superseding the older part number MDS65210402. If your dishwasher is leaking water around the door, leaving puddles on the floor, or the existing gasket is cracked, torn, or pulling away from the channel, this is the direct OEM replacement to restore a watertight seal.

The door gasket runs along the perimeter of the dishwasher tub opening and compresses against the door to form a watertight seal during every wash cycle. Over time, heat, detergent, and repeated cycling cause the rubber to harden, crack, or deform. This OEM part is manufactured to LG's original specification — same profile, same rubber compound, same fit as the factory original.

✓ Common Symptoms Fixed

Water leaking from the bottom of the dishwasher door, puddles forming on the floor during or after a cycle, visible cracks or tears in the door seal, gasket pulling away from the door channel, musty odour from moisture escaping the tub.

✓ Installation Tips

Disconnect power to the dishwasher before servicing. Open the door fully to access the gasket channel around the tub opening. Starting at a corner, pull the old gasket out of the channel — it is typically press-fit or seated in a groove. Clean the channel thoroughly to remove any residue or debris. Begin seating the new gasket at the top centre and work outward toward the corners, pressing firmly into the channel as you go. Close the door and run a short cycle to verify the seal before returning the unit to service.
