Customer Questions and Answers for Coupling by Whirlpool

This replacement coupling links and seals wash-system components so pressurized water reaches the spray arms. Replacing a cracked or worn coupling restores cleaning performance and helps prevent drips at the connection point.

• Provides a secure, watertight connection within the dishwasher wash system
• Helps deliver proper water flow to the spray arms
• Failure symptoms can include poor cleaning, spray arms not turning, a loose/detached feed tube, or leaks at the connection
• Replace if the coupling is cracked, deformed, or stripped

• Disconnect power and shut off water before servicing
• Remove dish racks and access the coupling at the manifold/feed-tube area per your model
• Inspect existing seals/O-rings and replace if worn
• Seat and lock the coupling fully; run a short cycle to check for leaks
