Step 3 · Prepare New Dishwasher for Installation
Carefully unbox the new dishwasher, making sure to remove all packing materials from the exterior and interior. Lay a piece of cardboard or a blanket on the floor and gently tip the dishwasher onto its back. This provides access to the underside where the plumbing connections are made. Locate the water inlet valve; it's usually a brass or plastic fitting near the front. Tightly wrap the threads of a new 3/8-inch 90-degree brass elbow with Teflon tape, wrapping 3-4 times in a clockwise direction. Screw this elbow into the dishwasher's water inlet valve and tighten it with an adjustable wrench, ensuring the opening faces the rear of the unit where the supply line will come from. Do not overtighten. Next, attach the new drain hose to the dishwasher's drain pump outlet, securing it with the provided spring or screw clamp.
