Bosch 00298594 Dishwasher Upper Spray Arm

Dishwasher Upper Spray Arm – Bosch

The dishwasher upper spray arm rotates during the wash cycle and distributes water through its nozzles downward to clean the dishes loaded in the upper rack. When the arm cracks, warps, or its nozzles become permanently clogged, water distribution is uneven and upper rack dishes come out dirty. This direct-replacement upper spray arm restores full, even water coverage on compatible Bosch dishwasher models.
