Bosch 00357045 Dishwasher Spray Arm

Dishwasher Spray Arm – Bosch

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