Inventory the job
List the water supply connection, drain arrangement, electrical connection and mounting method separately. Then compare the appliance’s included parts with the installer’s quote. This prevents buying a second drain hose while overlooking the required power connection or inlet fitting.
Built-in, rolling portable and countertop machines need different hardware. A faucet quick-connect kit does not serve the same purpose as a built-in supply line. Panel-ready appliances may also need model-specific brackets or decorative-panel hardware.
Match part numbers and fittings
Use the approved cord or junction arrangement, hose dimensions and connection types in the installation instructions. Manufacturer accessory catalogs can include parts serving several appliances, so an accessory appearing in a broad catalog is not proof it fits yours.
KitchenAid’s support listing illustrates the variety: supply lines, elbows, drain extensions, cords and mounting kits are separate items. Choose only the part specified for the model and installation. Have the installer resolve code-dependent electrical and drainage details.
Before checkout
- Ask which new hoses, fittings and seals the installer requires.
- Confirm hose length and routing without tight bends or unsupported extensions.
- Check whether an air gap or other drainage arrangement is required for the location.
- Include any countertop mounting bracket needed for the surface material.
- Get a written list of parts, labor and excluded work before delivery.
- Retain receipts and exact part numbers with the installation documentation.
