Restore proper lower-rack spray coverage with this genuine OEM Whirlpool Dishwasher Lower Spray Arm - WPW10319027. This lower spray arm rotates and distributes wash water across the lower rack to improve cleaning performance.

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

Fitment / What To Verify: Verify that your original part is the lower spray arm and compare the hub connection before ordering. Whirlpool-family dishwashers can use different lower, center, upper, and third-level wash-arm designs.

This part commonly replaces previous part numbers including W10319027.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Poor cleaning on the lower rack, weak spray action, or dishes that come out with residue.
• Visible/Sensory Cues: Cracked spray arm body, clogged spray holes, worn hub area, or an arm that no longer spins freely.

Pro Tip: Clean the filter and feed area while replacing the spray arm. Restricted water flow can mimic spray-arm failure and reduce the performance of the new part.
