Nut, Upper Spray Arm

About This Part

If your AEG dishwasher's upper spray arm has become loose or won't stay in place properly, a worn or damaged retaining nut is likely the culprit. This small but essential component holds the spray arm securely in position, and when it fails through general wear, your dishwasher won't clean dishes effectively. This genuine replacement nut (OEM reference 140176494015) is a straightforward fix for most DIY homeowners. The installation difficulty rating of 2 means it's relatively simple—you'll just need to access the upper basket area and secure the nut firmly without over-tightening, which could crack the plastic fitting underneath. Before ordering, it's worth taking a few minutes to locate your dishwasher's E-Nr model number, usually found on a sticker inside the door frame or on the side wall of the cabinet. This ensures complete compatibility with your specific AEG model and prevents any fitting issues. With this genuine part and a bit of care during installation, your spray arm will be working like new again.
