The Upper Spray Arm Water Tube is an OEM part for Bosch dishwashers. It is a vital component of the washing mechanism responsible for spraying water across the upper rack.
Over time, mineral deposits can clog the narrow openings of the water tube, reducing water pressure and spray effectiveness. Accidental bending or cracking of the flexible water tube could also cause spray issues.
Symptoms of a bad upper spray arm and water tube include:
- Incomplete cleaning of dishes on the upper rack
- Dried food soils left behind after washing
- Noticeably weaker water spray pressure from the arm
- Possible leaks or drips around the arm connection point
Replacing with this OEM Bosch part restores full spray coverage and optimized washing for all rack levels. It is also compatible with certain Miele, Asko, and Jenn-Air professional-grade dishwashers.
