• Routes water from the rear feed tube to the upper/middle spray arm
• Self-adjusts with rack position to keep a secure, leak-resistant connection
• Replace if cracked, deformed, or the coupling no longer seals
• Common symptoms include poor cleaning on the upper rack, weak spray, upper spray arm not turning, or a small leak at the back of the tub

• Disconnect power and shut off water; wear gloves for protection
• Remove the upper rack by releasing the rail end caps and sliding the rack out
• Unclip the manifold from the rack and disengage it from the rear feed port; seat the new manifold fully
• Reinstall the rack and ensure the spray arm spins freely
