Customer Questions and Answers for Spray Arm by Bosch

The Spray Arm is an OEM part for Bosch dishwashers. It is responsible for evenly distributing water across the dish racks during wash cycles using a rotating arm and nozzle design.

Causes of a bad spray arm can include mineral or limescale buildup that inhibits water pressure/flow, or damage from accidental impact that impacts its rotation. Over time, normal wear and tear on plastic spray arms can also affect optimal spray coverage.

Symptoms of a bad spray arm include:

• Poor or uneven cleaning results
• Dirt or food debris remaining on dishes after cycles complete
• Clogs or blockages in the arm and nozzle openings

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.
