3920DD3005H Genuine Tub Door Seal for LG Dishwashers, LG Packing Gasket 3920DD3005 Series, H Version

LG lists 3920DD3005H simply as packing, its term for a rubber seal. The 3920DD3005 number family is used for the seal that runs around the tub opening of LG dishwashers, where the door closes against it, and H marks this particular version. No model list is on file, so make sure the code on your old seal, including the last letter, matches before you order.

LG dishwasher leaking from the door

The tub seal is a moulded rubber strip pressed into a channel around the front of the tub. When the door closes it squashes against the seal and keeps wash water inside. Over time the rubber hardens, shrinks, splits or gets chewed by cutlery and food scraps, and water starts to escape. Signs include puddles in front of the dishwasher, water marks or rust at the bottom of the door, damp kick boards and swollen benchtop or cabinet edges. Check that the door closes square and the dishwasher is level before replacing it.

Fitting the dishwasher seal

Turn the dishwasher off at the wall. Pull the old seal out of its channel and clean away any grime or detergent build-up underneath. Note where the ends of the old seal sat, then press the new one into the channel from the same spot, working evenly around without stretching it. A little warm water softens a seal that has been folded in its packet. Run a cycle and check for drips.

Questions about this part

Will 3920DD3005A or 3920DD3005J fit instead?

Not necessarily. LG uses the final letter to separate versions of the same seal, and length or profile can differ between them. Match the full code on your old seal, or send your dishwasher's model number through the parts enquiry form.
