This generic lower spray arm is a compatible replacement for Smeg parts 764570114 and 764570188. It's an aftermarket arm rather than a Smeg branded one, made to suit Smeg dishwashers such as the DWA147X and DWA157X, the DWA314X and DWA315X, plus DWA6214S, DWA6314X2 and DWAU315X1. Fit it when the old arm is cracked, warped or no longer spinning freely.

Smeg dishwasher not cleaning the bottom rack

The lower spray arm sits under the bottom basket and spins on jets of water forced out through its nozzles, blasting the dishes from below. When the arm cracks, water escapes through the split instead of the jets, so pressure drops and the arm may stop turning. Blocked nozzles, a broken hub or a bent arm that catches on the basket cause the same problem. The usual result is dirty plates and pots on the lower rack and gritty residue in corners, while the top basket still comes out clean. Spin the arm by hand and look for cracks along its length.

Changing the lower spray arm

With the dishwasher switched off at the wall, roll out the lower basket. Most lower arms lift straight off or release with a twist of the centre hub. Clear the hub seat and filter area of any debris before fitting the new arm, then press it on and spin it by hand to confirm it turns without catching on the basket or the filter.
