LG Dishwasher door vent gasket MDS65210501, Replaces MDS65210502

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Moisture or water appearing along the lower edge or side of the dishwasher door
• Water escaping from the vent area during a wash cycle
• Steam or condensation escaping around the vent instead of through the intended vent path
• Visible gasket distortion, cracking, tearing, compression, or loss of seating around the vent duct

Check Before Replacing

• With the dishwasher empty and cool, inspect the vent gasket and surrounding vent duct for visible tears, gaps, distortion, or debris.
• Check that the vent cover or vent assembly is seated securely and that the gasket is positioned continuously between the door panel and vent duct.
• Wipe the lower door edge and vent area dry, then observe the area during a supervised cycle to identify whether moisture reappears near the vent; do not place hands near hot water or steam.
• Verify the dishwasher door closes and latches without interference, since door misalignment can prevent the vent gasket from sealing correctly.
• Disconnect electrical power before removing any door panel or attempting part replacement.
