Restore upper-level dishwasher spray coverage with this genuine OEM Whirlpool Dishwasher Upper Spray Arm Spinner - WPW10327455. This upper spray arm spinner, often described as the third-level spray arm, rotates and directs water to improve cleaning at the upper portion of the dishwasher.

Compatibility: Whirlpool, KitchenAid, Maytag, Jenn-Air, Amana, Estate, Roper, Admiral, and select Kenmore dishwasher platforms

Fitment / What To Verify: Verify the original spray-arm location before ordering. Official sources identify this part as an upper wash arm spinner / third-level spray arm, not a lower-arm assembly.

This part commonly replaces previous part numbers including W10327455.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Poor cleaning at the upper level, weak spray action, or residue left on upper items.
• Visible/Sensory Cues: Cracked arm, blocked spray openings, worn hub, or an arm that no longer spins freely.

Pro Tip: Check the feed tube and any retaining fastener during the repair. Restricted water flow or a missing fastener can reduce spray-arm performance.
