Julie J Lawton , OK April 20, 2025 I needed a new dishwasher upper spray arm for a bosch dishwasher i couldn't find it other web sites they all said it had been discontinued not so apparently Super easy fix. I just needed the spray arm itself. Unscrewed the arm part and installed successfully, less than 1 min. Saved a lot of money buying the part instead of a whole new dishwasher.
