How often should a dishwasher door gasket be replaced?

A dishwasher door gasket typically lasts many years. Replacement is generally needed only when visible signs of wear, damage, or leaks appear. Regular cleaning can help extend its lifespan by preventing food debris and detergent buildup from degrading the material.

Can a leaky door gasket damage my floor?

Yes, persistent water leaks from a faulty door gasket can cause significant damage to kitchen flooring, cabinetry, and subflooring over time. Prompt replacement is important to prevent water damage and potential mold growth, protecting your home's structure.

Is it normal for a new gasket to feel stiff?

Yes, a new door gasket may feel stiffer than the old one, and the dishwasher door might be harder to close initially. This is normal as the new seal needs time to compress and conform to the door frame. Running a few hot wash cycles can help it soften and seat properly.
