Bosch 00448806 Dishwasher Lower Spray Arm

Dishwasher Lower Spray Arm – Bosch

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