Customer Questions and Answers for Middle Spray Arm Hub (Dishwasher) by Ge

This middle spray arm hub mounts the mid-level spray arm to its supply tube so it can spin freely and distribute wash water to the upper rack. Replacing a worn hub restores cleaning and keeps the arm secure.

• Attaches and centers the mid-level spray arm on its mount
• Provides a smooth bearing surface for proper arm rotation
• Helps deliver even spray coverage to the upper rack
• Common symptoms: poor cleaning on upper rack, middle arm not spinning, arm wobbling or falling off, unusual rattling from the arm area

• Disconnect power and shut off water before servicing
• Remove the middle spray arm assembly to access the hub
