Secure your lower spray arm to the pump hub and maintain full water pressure across the lower dish rack. This genuine factory OEM lower wash arm retainer nut screw fastens the spray arm spindle directly to the center conduit, keeping the arm level and rotating smoothly without wobbling loose under heavy wash cycles.

  • Part Numbers: WP8268873 (Replaces: 9742945, 8268873, AP6012351, PS11745564, EAP11745564, 830911, AH11745564, EA11745564)

  • Design: Molded heavy-duty polymer center retainer bolt with engineered reverse/standard coarse retaining threads and a textured top flange for secure seating.

  • Compatibility: Whirlpool, Kenmore (665 series), KitchenAid, Maytag, Estate, Roper, and Inglis built-in dishwashers.

Pro Tip: Note thread direction when removing the old retainer—many center wash arm spindle screws use reverse (left-hand) threads to keep from loosening during water rotation.
