Upper Rack Not Cleaning on Your Whirlpool or KitchenAid Dishwasher? Replace Upper Spray Arm W11043430 and Restore Full Wash Coverage
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.
⚠️ While You're In There: If the spray arm was clogged rather than cracked, the spray arm feed tube and upper rack manifold may also be partially blocked. Flush the feed tube and inspect the manifold connection before reassembling — a blocked feed tube will starve the new arm of water pressure and leave you with the same poor cleaning result.

Pull out the upper rack, locate the spray arm mounting point at the centre of the rack, twist or unclip the old arm counterclockwise to release it, and snap or twist the new arm into place.

💡 Pro Tip — Check the Feed Tube Before You Close It Up:
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.
