This coupler and hose assembly connects your portable dishwasher to the sink faucet during operation. It supplies fresh water and returns drain water to the sink, helping stop leaks and restore reliable filling and draining.

  • Provides a quick-connect link to a compatible faucet adapter for temporary hookup
  • Carries incoming water to the dishwasher and routes drain water back to the sink
  • Maintains a secure, leak-resistant seal during wash and drain cycles
  • Replace if the coupler won't attach or stay on the faucet, hoses are cracked/kinked, or you see leaks and poor fill/drain performance
What's included: One coupler with attached hose assembly
  • Unplug the appliance and turn off water before service
  • Verify the faucet adapter and O-rings are in good condition; hand-tighten only—do not overtighten with tools
  • Route hoses to avoid kinks and sharp bends
  • Open the faucet slowly and run a short test cycle; check all connections for leaks

Stephanie, The part number you supplied is designed for a portable dishwasher. You'd most likely be better off to order and install W10849778. This component was designed and installed on compact washing machines when installed in a "portable" configuration similar to your description. You may have to make a few minor modifications to make it work on your unit, depending on brand and model number you select.
