Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Water or puddling at the front, sides, or bottom of the dishwasher door during or after a cycle
• Visible cracking, tearing, brittleness, flattening, or deformation of the gasket
• Door closure feels different, requires extra force, or does not compress the seal evenly
• Visible residue, mold, or mildew on the gasket that cannot be adequately cleaned

Check Before Replacing

• With the dishwasher empty and power disconnected, visually inspect the gasket around the tub opening for cracks, tears, gaps, flattening, twisting, or sections pulled out of the channel.
• Check that the gasket is seated evenly and continuously in its channel, without pinched or displaced sections.
• Inspect the mating sealing surfaces for food debris, detergent residue, mineral buildup, or other contamination that could prevent uniform contact.
• Close the dishwasher door slowly and check for obvious areas where the gasket folds, bunches, or fails to contact the mating surface; do not force the latch.

Installation Notes

• Disconnect electrical power to the dishwasher before servicing.
• Open the door and gently remove the old gasket from its channel; a suitable flat-blade tool may help lift an edge if needed, but avoid damaging the tub or sealing surface.
• Clean debris and residue from the channel and allow it to dry before fitting the replacement.
• Locate the midpoint of the new gasket and press it into the top-center of the channel, then work evenly toward both sides.
• Do not stretch or twist the gasket. Confirm it is fully and evenly seated around the perimeter.
• Close the door slowly to check that the gasket is not pinched and that the door closes and latches normally. Follow the appliance-specific service literature if it differs.
