Customer Questions and Answers for Sump Gasket (Dishwasher) by Lg

This dishwasher sump gasket seals the joint between the sump assembly and the tub to prevent leaks and maintain wash performance. Replace it if the old seal is worn, flattened, cracked, or damaged to stop water escaping beneath the unit.

• Creates a watertight seal where the sump attaches to the tub
• Helps prevent water leaks from the base of the dishwasher
• Supports proper circulation and overall wash performance
• Common failure signs: puddles under the unit, leaks during a cycle, or a visibly torn/deformed gasket

• Disconnect power and turn off the water supply before servicing
• Access the sump from inside the tub (remove lower rack, spray arm, filters, and sump cover) or from below, depending on model
• Clean mating surfaces; install the new gasket evenly without twists or gaps
• Reassemble and run a short cycle to check for leaks
