Description
Product Overview
The HLTIT dishwasher lower spray arm (part number WPW10491331) is engineered to match the original equipment specifications of Whirlpool, Amana and Ikea dishwashers. Constructed from high‑grade stainless steel, the arm resists corrosion and maintains structural integrity even after repeated exposure to hot water and detergent. Its integrated heat shield protects the rotating components from thermal stress, extending the service life of the spray arm and preserving the efficiency of the wash cycle.
Measuring 1.89 x 0.7 x 0.89 inches and weighing just 5.9 ounces, the unit fits seamlessly into the lower rack of compatible models. The design incorporates precision‑machined spray nozzles that deliver a fine, evenly distributed water mist, ensuring that every dish, glass, and utensil receives thorough cleaning. The central tower extends upward through the hydraulic lower frame, providing stable rotation and optimal water coverage.
Each HLTIT lower spray arm comes with a one‑year manufacturer warranty, reflecting confidence in material quality and manufacturing processes. The part is packaged with all necessary components for a straightforward installation, eliminating the need for additional hardware in most cases. Compatibility is verified against part numbers W10491331, PS11755592, and 2312843, among others, guaranteeing a perfect fit for a wide range of dishwasher models.
Beyond its functional attributes, the spray arm is designed with user convenience in mind. The smooth surface reduces the likelihood of food particles adhering to the arm, simplifying routine cleaning and maintenance. The heat shield also minimizes the buildup of mineral deposits, a common issue in areas with hard water, thereby preserving spray performance over time.
Overall, the HLTIT lower spray arm delivers a balance of durability, performance, and ease of installation, making it an ideal choice for homeowners seeking to restore or upgrade their dishwasher’s cleaning capability without compromising on quality.

Usage
This replacement part is intended for use in residential kitchen environments where dishwashers are a daily necessity. It is suitable for standard load cycles, including heavy‑pot and delicate glass settings, providing consistent water distribution regardless of the selected program. Homeowners can expect reliable operation during both short, quick washes and longer, high‑temperature cycles, thanks to the built‑in heat shield that mitigates thermal wear.
Installation typically requires the removal of the existing lower spray arm, followed by the attachment of the new HLTIT unit using the supplied mounting hardware. The process can be completed in under fifteen minutes by a DIY enthusiast with basic hand tools, or by a professional appliance technician. Once installed, the arm operates silently, contributing to a quieter kitchen environment during dishwasher operation.
For optimal performance, it is recommended to periodically inspect the spray nozzles for any blockage and to clean them with a soft brush if necessary. This maintenance step ensures that water flow remains unobstructed, preserving the arm’s ability to deliver a uniform spray pattern across all dishes.
The part is also compatible with aftermarket dishwasher models that share the same mounting dimensions and hydraulic specifications, expanding its applicability beyond the primary brand list. Whether replacing a worn component or upgrading an older unit, the HLTIT lower spray arm integrates seamlessly into existing dishwasher systems.
