Dishwasher center wash arm, also described as a middle or third-level spray arm. It sprays wash water toward the dish load and mounts beneath the middle rack on applicable models.

Is This the Right Part?

Common Symptoms

• Middle-rack dishes remain dirty when the spray arm is clogged, damaged, or unable to rotate properly.
• Reduced wash coverage when debris or mineral buildup blocks the spray-arm openings.
• A cracked or damaged arm may leak water and fail to rotate effectively.

Check Before Replacing

• With power disconnected, visually inspect the arm for cracks, broken mounting tabs, or warping.
• Check that the spray openings are not blocked by food debris or mineral buildup.
• After installation, manually confirm that the arm rotates freely and does not contact the rack or other components.
