Customer Questions and Answers for Lower Spray Arm by Frigidaire

The Lower Spray Arm is an OEM component specifically designed for Bosch dishwashers. It spreads cleaning water and detergent beneath dishes on lower racks and shelves. 

Uniform coverage is provided through the spinning spray of multiple strategically placed nozzles. Dedicated lower basket washing power tackles tough soils.

Causes of spray arm malfunction can include clogs from food debris accumulations over time. Impeller damage from hard impacts inside the wash chamber is also possible.

Symptoms of a defective lower spray arm include: 

• Poor or ineffective cleaning on lower racks and surfaces
• Dried-on food remaining in hard-to-reach crevices below  
• Noticeable decreases in water pressure impacting lower wash

This OEM Bosch replacement part is also compatible with Thermador, Gaggenau, and some Kenmore models sharing uniform wash architectures. Replacement ensures balanced upper and lower cleaning performance.
