Part WPW10340504 Dishwasher Middle Spray Arm
Purpose
Distributes water to clean the upper dish rack.
Details
The WPW10340504 is a genuine OEM middle (center) spray arm assembly for Whirlpool-built dishwashers. Mounted directly to the bottom of the upper dish rack, this rotating arm utilizes high-pressure water jets to ensure thorough cleaning of dishes, glassware, and utensils. Its precision-engineered nozzles are designed to create a specific spray pattern that covers the entire upper compartment. Over time, the plastic arm can become clogged with mineral deposits, food debris, or sustain physical damage from tall utensils, leading to poor wash performance or spotted dishes. Replacing a damaged spray arm restores the necessary water pressure and rotational speed required to meet factory cleaning standards without the need for manual pre-scrubbing.
