The lower spray arm is responsible for distributing water across every dish on the bottom rack during each wash cycle. When it cracks, breaks, or its jets clog beyond cleaning, water pressure drops and the bottom rack stops getting clean — dishes come out with food residue, spots, or grit no matter how long the cycle runs. Part 5304507158 is the genuine OEM lower spray arm for compatible Frigidaire and Electrolux dishwashers, replacing 154821902, 154821903, 5304496935, 5304498139, and 5304507159.

💡 Pro Tip — Clean Before You Replace:
Before ordering, remove the spray arm and flush the jets under running water — mineral deposits and food debris can clog the holes and mimic a broken arm. If cleaning restores spin and pressure, you may not need a new arm. If the arm is cracked, warped, or still won't spin freely after cleaning, replacement is the correct next step.
