Customer Questions and Answers for Upper Spray Arm (Dishwasher) by Whirlpool

This replacement upper spray arm restores strong spray coverage to the upper wash level of your dishwasher. It channels water through its jets and spins under pressure to help deliver consistently clean dishes on the top rack.

• Directs pressurized wash water to the upper wash level for thorough cleaning
• Rotates under water pressure for even spray coverage
• Helps clear food soils and detergent residue from dishes and glasses
• Common symptoms: poor cleaning on the upper rack, spray arm not spinning, clogged or cracked arm

• Disconnect power and shut off the water supply before servicing
• Open the dishwasher; remove the upper rack if needed for access
• Release or unthread the retainer and pull the old arm straight off; clear debris from the hub/feed port
• Seat the new arm and secure the retainer hand-tight; ensure the arm spins freely and run a test cycle
