The Frigidaire 809006501 Bottom Door Gasket seals the lower edge of the dishwasher door to prevent water from leaking during wash cycles. This replacement gasket fits along the bottom of the door and creates a tight barrier between the door and tub when closed. A properly fitted gasket keeps wash water inside the dishwasher and can reduce leaks around the door area. A worn, cracked, or damaged gasket may allow water to escape during use. Replacing the gasket can restore proper sealing and support cleaner, more controlled dishwasher use.
