Key Features

• Optimal Coverage Design: Specifically engineered to rotate and deliver a high-velocity spray pattern, ensuring water reaches all corners of the lower dish rack.
• High-Temperature Durability: Molded from heat-resistant, food-grade polymers that maintain structural integrity during intense sanitize and heated-dry cycles.
• Precision Spray Nozzles: Features calibrated apertures designed to maintain consistent water pressure for effective removal of stubborn food particles.
• Balanced Rotation: The lightweight yet rigid construction ensures the arm spins freely with minimal water resistance, maximizing the efficiency of the wash motor.

When to Replace

• Inadequate Cleaning: Dishes on the bottom rack remain greasy or gritty, suggesting the arm is stuck or the nozzles are blocked.
• Split Seams: The plastic housing has separated at the edges, causing water to spray out of the sides rather than the nozzles, which stops the arm from spinning.
• Heat Damage: The arm has warped or melted due to contact with the heating element or excessive thermal stress.
• Worn Mounting Hub: The center connection has become loose or "stripped," causing the arm to wobble or fall off the support post.
• Visible Clogs: Hard water minerals (calcium/lime) have permanently obstructed the spray holes.

Installation Tips

• Safety First: Ensure the dishwasher is turned off and the lower rack is removed to allow for a clear work area.
• Simple Removal: This arm is typically secured by a center bolt or a snap-fit hub. If there is a center bolt, it may be left-hand threaded (turn clockwise to loosen).
• Clear the Sump: Before installing the new arm, check the dishwasher sump and filter area for debris that could be pumped back into the new spray arm.
• Manual Spin Test: Once the new arm is installed, spin it by hand to ensure it does not hit the heating element or the dishwasher walls.
• Seal Check: Verify the washer or gasket at the base of the spray arm is in good condition to prevent pressure loss at the hub.
