00668385 Bosch Upper Wash Arm Assembly

The Upper Wash Arm Assembly is a crucial part found in Bosch dishwashers, also suitable for certain models from Thermador, Gaggenau, and Kenmore. This Original Equipment Manufacturer (OEM) component is positioned on the lower rack of the dishwasher and rotates to distribute water uniformly over the dishes throughout the cleaning cycle.

Common indicators of a malfunctioning spray arm include dishes that are not thoroughly cleaned after several wash cycles, residual soap scum or food particles in difficult-to-clean spots, and dishes that have dry patches or spots due to inadequate rinsing.

The typical reasons for spray arm failure often involve worn or broken arm brackets that restrict proper movement, cracks in the arm that reduce water flow, or mineral deposits that block the arm’s full rotation.

This replacement part ensures compatibility with various dishwasher brands and models, maintaining optimal performance in water distribution during the wash cycle.
