Dishwasher Spray Arm Top Nut

About This Part

When your dishwasher's spray arms aren't rotating properly or water isn't reaching your dishes, a worn or damaged top nut is often the culprit. This small but essential component holds the spray arm securely in place, and general wear over time can cause it to loosen or fail completely. This genuine AEG replacement nut (OEM reference 8072403010) restores the tight fit your spray arm needs to function correctly. It's a straightforward fix that most DIY homeowners can tackle in just a few minutes. Installation difficulty is rated at level 2, making this one of the more accessible repairs. Before you begin, simply unscrew the old nut by hand or with a spanner, then thread the new one on until snug. Don't overtighten, as this can crack the plastic fitting underneath. The whole job typically takes less than five minutes, and you'll immediately notice improved spray coverage across your dishes. Before ordering, please verify your dishwasher's E-Nr model number matches our compatibility information to ensure this part is correct for your appliance.
