Whirlpool Dishwasher Spray Arm - W11579565

Restore proper dishwasher spray coverage with this genuine OEM Whirlpool Dishwasher Spray Arm - W11579565. This lower spray arm rotates and directs wash water across the dish load so detergent and water can reach the correct rack area.

W11579565 is a dishwasher lower spray arm used when the original arm is cracked, clogged, melted, loose, or no longer rotates correctly.

Compatibility: Fits select Whirlpool-built dishwasher platforms including Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, and some Kenmore models that use the W11579565 stainless-style lower spray arm assembly.

This part commonly replaces previous part numbers including W11164607, AP7180514.

Fitment / What To Verify: Verify full dishwasher model number, lower spray-arm position, mounting post, feed tube, overall arm length, rack clearance, and whether your model uses W11579565 or the later W11806547 replacement.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Dishes not cleaning well, poor spray coverage, food residue on one rack, spray arm not spinning, water hitting the door incorrectly, or noise from a loose arm.
• Visible/Sensory Cues: Cracks, melted plastic, clogged spray holes, broken mounting hub, worn support point, arm dragging on dishes, or arm that does not spin freely by hand.

Pro Tip: Before replacing the arm, clean debris from the sump/filter area and check the feed tube or support. A blocked filter, weak pump, or misloaded rack can cause poor cleaning even with a new spray arm.
