Whirlpool Dishwasher Door Vent Gasket WP8269259, Replaces 8269259

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Visible water or moisture around the vent or nearby lower door area
• A gasket that is cracked, hardened, flattened, displaced, or otherwise damaged
• Moisture marks or mineral deposits near the vent assembly

Check Before Replacing

• With the dishwasher disconnected from power and the door area dry, visually inspect the vent gasket for cracking, hardening, deformation, displacement, or gaps.
• Check that the gasket is seated continuously in the vent assembly groove and that the vent cover is fully secured.
• Inspect the surrounding vent assembly and door panel for cracks, distortion, mineral buildup, or debris that could prevent an even seal.
• If leakage continues after inspection or gasket replacement, check the vent assembly and other door-sealing components rather than assuming the gasket is the sole cause.
