Step 5 · Position and Level New Dishwasher
Carefully slide the new dishwasher part-way into the cabinet opening. Before pushing it all the way in, feed the drain hose, the new water supply line, and the electrical cable through the access hole in the side of the cabinet into the sink base. Once the lines are through, push the dishwasher the rest of the way in. Use a level on the top edge of the inner door to check for levelness side-to-side and front-to-back. Adjust the dishwasher's feet with an adjustable wrench until it is level and fits snugly beneath the countertop.
