The spray arm shaft supports the rotation of the spray arm (the rotating wash or rinse arm) in the professional dishwasher, complete with bearings for smooth, quiet rotation.

Connected components: the ring nut with hook (without cross-piece, for C43/48/60E models) secures the arm to the shaft, the oval rinse nozzles (calibrated bore, sold in packs of 6 with matching O-ring) regulate water pressure and direction.

Frequently asked questions

The spray arm no longer turns: what should I check?
Check the shaft and its bearings: if worn or seized, the wash arm won't rotate correctly.

Rinsing is uneven on some dishes?
Check the nozzles: if clogged or damaged, the water jet loses its uniformity.
