The spray arm rotates during the wash cycle to distribute water across all rack levels. A damaged or blocked spray arm directly reduces wash quality. This OEM part is manufactured to the original specification — same fit, same spray pattern, same performance as the original.
Dishes not getting clean, standing water on dishes after cycle, spray arm not spinning, cracked or broken spray arm, clogged spray arm nozzles that can't be cleared.

Disconnect power to the dishwasher before servicing. Remove the lower rack to access the spray arm. The spray arm typically snaps or screws onto the center hub — note the attachment style before removing the old part. Rinse the new spray arm before installing. Restore power and run a short cycle to confirm even water distribution.
