GE Dishwasher Upper Spray Arm WG04L00566, U.S. Cross-Reference WD22X10081

WG04L00566 is a genuine GE dishwasher upper spray-arm assembly. Its matching U.S. service reference is WD22X10081. The spray arm rotates during the wash cycle and distributes pressurized water across dishes in the upper rack. A cracked, blocked or damaged spray arm may contribute to poor upper-rack cleaning, food residue remaining on dishes or uneven spray coverage. The spray arm distributes wash water to the upper rack but does not pump or drain water. Confirm the complete dishwasher model before ordering — similar-looking spray arms may use different mounting connections, dimensions or water-feed designs.

Is This the Right Part?

Confirm the complete model number before ordering. Similar spray arms may differ in length, mounting connection, and water-feed design. Do not order based on appearance alone.

Common Symptoms

• Upper-rack dishes not cleaning properly — food residue remaining on glasses or cups
• Weak or uneven water coverage across the upper rack
• Spray arm not rotating freely during the wash cycle
• Water spraying in the wrong direction or with reduced pressure
• Visible cracks, distortion or blocked spray openings on the arm

Check Before Replacing

• Remove the spray arm and inspect for cracks, distortion and blocked spray openings — clean blocked holes with a toothpick or thin wire
• Confirm the arm spins freely on its mounting post — a worn or damaged mount can restrict rotation without damaging the arm itself
• Check the water-feed conduit and upper-rack water supply connection for blockage or damage
• Verify the dishwasher filter and sump are clean — a restricted filter reduces water pressure to all spray arms

Installation Notes

1. Disconnect electrical power and shut off the water supply before servicing the dishwasher.
2. Remove the upper rack to access the spray arm mounting post.
3. Photograph the mounting connection and water-feed attachment before removal.
4. Compare WG04L00566 with the original arm — confirm length, mounting connection and spray-opening pattern match.
5. Inspect the water-feed conduit and mounting post for damage before installing the new arm.
6. Restore power and water, then run a wash cycle to confirm the arm rotates freely and upper-rack cleaning is restored.

Use a qualified technician when diagnosis or installation is outside your experience.
