This walk follows a dishwasher install in the order the work usually runs. The goal is a unit that sits level, drains clean, takes water and power where the manual says, and runs a test cycle without leaks. Use the manufacturer's install sheet for the exact fittings on your model, and check local code for the drain and power routes.
Before delivery
Measure the width, height, and depth of the opening, and note the clearance at the top and sides. Check the floor under the opening for level and for soft spots. Confirm the water shutoff valve under the sink turns freely, and note where the drain outlet and the power source sit. Clear the path from the door to the opening.
Water and drain
Connect the supply line to the valve, using the fitting the model calls for. Route the drain hose with a high loop, or use the air gap the install sheet and local code require, then connect to the disposal inlet or drain as the sheet shows. Tighten fittings by hand first, then snug them. Keep the hoses clear of sharp edges and heat.
Power and placement
Confirm the outlet or circuit meets the manual's requirement and stays reachable after the unit is in. If the outlet or circuit needs new work, that is a licensed trade job. Slide the unit into the opening without pinching the hoses or the cord. Set the leveling feet, then check the top edge with a level. Secure the unit to the cabinet at the mounting points the manual lists. The Dishwasher page has the typical service life for planning after the install is done.
The first cycle
Run an empty cycle while you watch the supply connections, the drain hose, and the floor under the unit. Look for drips, slow drainage, or water tracking along the cabinet bottom. Then run a short cycle with a load, and check the door seal, the drain, and the sound of the pump. If anything leaks, shut off the water valve before you touch a fitting.
