Whirlpool KitchenAid Dishwasher Upper Spray Arm W11043430 – Genuine OEM Replacement
When the upper spray arm in your Whirlpool or KitchenAid dishwasher cracks, clogs beyond clearing, or stops spinning freely, the top rack stops getting clean — glasses come out cloudy, bowls come out with food still stuck, and you're running loads twice. Part W11043430 is the genuine OEM upper spray arm that restores full water distribution across the upper rack. It's a direct-fit replacement requiring no modifications, designed to seat and spin exactly as the original.

The upper spray arm gets its water through a feed tube that runs up the back of the upper rack. If the arm was clogged, there's a good chance the feed tube has mineral buildup too. Run water through it before installing the new arm — a restricted feed tube will starve the arm of pressure and leave you with the same weak cleaning result even with a brand new part.
