Whirlpool Dishwasher Lower Spray Arm - WPW10340527

Restore proper lower-rack spray coverage with this genuine OEM Whirlpool Dishwasher Lower Spray Arm - WPW10340527. This lower spray arm rotates during the wash cycle and helps distribute water across the lower rack for more even cleaning.

WPW10340527 is a genuine OEM Whirlpool dishwasher lower wash arm used when the original arm cracks, clogs, or no longer spins correctly. Official parts sources identify this part as a lower wash arm, so lower-rack location matters when ordering.

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. This lower-arm design is not interchangeable with middle, upper, or third-level spray-arm parts.

This part commonly replaces previous part numbers including W10340527.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

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

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