Door Gasket

OEM: 140055636017

Is water pooling around your dishwasher door or escaping during the wash cycle? A worn door gasket is likely the culprit. Over time, the rubber seal deteriorates from repeated opening and closing, losing its ability to create a watertight barrier and allowing water to leak onto your kitchen floor. This genuine AEG door gasket (OEM reference 140055636017) restores a proper seal between the door and tub, eliminating leaks and preventing water damage to your kitchen. Replacing it is straightforward, making it an ideal DIY repair for most homeowners. Installation is rated difficulty level 2, typically taking less than an hour. The most important tip is to ensure the gasket sits evenly in its groove all the way around before closing the door. Uneven seating is the most common cause of continued leaks after replacement. The gasket slots into the channel around your dishwasher's inner door frame, and removal simply requires gentle prying to release the old seal. Before ordering, verify your appliance's E-Nr model number on the rating plate inside the door frame to confirm compatibility with your specific AEG dishwasher model.
