WPW10448645 is a genuine OEM Whirlpool dishwasher center wash arm assembly used when the original arm cracks, clogs, or no longer rotates correctly. Official Whirlpool sources identify it as a center wash arm assembly, even though some secondary listings describe it more generally as an upper spray arm.

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 Whirlpool sources identify this part as a center wash arm assembly, so it should not be ordered as a lower-arm replacement.

This part commonly replaces previous part numbers including W10448645.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Poor cleaning results, weak spray action, or dishes left with residue in the affected spray zone.
• Visible/Sensory Cues: Cracked arm body, blocked spray holes, worn hub area, or an arm that no longer rotates freely.

Pro Tip: Inspect the feed connection and any support bracket during the repair. Water-delivery or mounting problems can reduce the performance of the replacement arm.
