O-ring,heater,circulation Pump,58x3,6mm

About This Part

If your AEG dishwasher isn't heating water properly or you've noticed leaks around the circulation pump area, a worn o-ring could be the culprit. This essential seal deteriorates over time through normal use, causing water to escape from the heating circuit and reducing your dishwasher's cleaning performance. Replacing this o-ring (OEM reference 140039688019) is a straightforward repair that most DIY homeowners can tackle confidently. The installation difficulty rating of 2 means it's accessible without specialist knowledge or expensive callout fees. Before you start, make sure the dishwasher is completely drained and powered off. A helpful tip: apply a thin layer of food-grade silicone grease to the new o-ring before installation—this makes fitting easier and helps create a better seal against future leaks. This seal addresses general wear and failure issues in the circulation pump system, restoring proper heating function and preventing water damage to your appliance. Before ordering, please verify your dishwasher's E-Nr model number matches our compatibility information to ensure you receive the correct part.
