Customer Questions and Answers for Middle Spray Arm by Bosch

The Middle Spray Arm is an OEM replacement part for Bosch dishwashers. It is a rotating component located in the lower dishwasher rack that assists in evenly distributing water across dishes during the wash cycle. 

Symptoms of a bad spray arm include:

• Incomplete cleaning of dishes, even after multiple cycles  
• Soap scum or food soils remaining in hard-to-reach areas
• Dishes coming out either spotty or dry in areas not rinsed properly

Causes of spray arm failure can be worn out or damaged arm brackets preventing proper rotation, cracks in the arm itself inhibiting water coverage, or mineral buildup inhibiting 360-degree rotation. 

This OEM Bosch replacement part is also compatible with some Thermador, Gaggenau, and Kenmore dishwashers.
