Installing the New Dishwasher

Bring your new dishwasher unit with you to the installation site. Take it apart and read the instruction manual. Turn the dishwasher over so that the underside is visible and reachable.

  1. Turn on the water source.

Attach a piece of Teflon tape to the bottom of the dishwasher’s water inlet line. Using an adjustable wrench, screw the brass fitting at a 90-degree angle onto the taped inlet pipe. Brass fittings are available at hardware stores. However, the majority of dishwasher units do not come with these.

After obtaining the fitting, attach the new water supply line to the brass fitting’s elbow. Place the other end of the waterline on the floor beneath the kitchen sink after passing it through one of the cabinet openings.

  1. Join the drain pipe.

Find the dishwasher drain discharge pipe, attach the dishwasher’s drain line to it, and tighten the connection with a hose clamp. The other end of the drain line should be directed towards the washbasin drain tailpiece after passing through the cabinet opening.

  1. Place the dishwasher by sliding it in.

Affix the movable legs to the dishwasher’s front. Gently slip the dishwasher into the cabinet beneath the countertop. Before sliding it all the way in, stop midway and make sure everything is in its proper place. Attach the other end of the water line to the dual shut-off valve beneath the kitchen sink to complete the connection.

Connect the drain hose to your sink’s drain tailpiece or, if you have one, your garbage disposer by means of an air gap. Before attaching the drain hose to the trash disposal or sink drain tailpiece, create a high loop with it if there isn’t an air gap.

  1. Attach the electrical cables

Take off the access panel’s lid and unscrew the junction box’s cover plate. Join the wire at the junction box with the wire coming from the circuit breaker. After that, attach the black wire to the black, the green wire to the ground wire, and the white wire to the white wire at the junction box.

To firmly fasten the connection in the junction box, use wire nuts. After closing the access panel, screw back the junction box’s cover plate. If a power cord was wired to your new dishwasher during production, you can skip this step.

  1. Finish Up the Install

To make sure the dishwasher is working properly, give it a test run. Inspect the water and drain lines for any leaks. Furthermore, look for leaks near the dishwasher. If there’s no problem, raise or lower the dishwasher’s legs to change its height.

Using a screwdriver, attach the metal brackets to the countertop’s underside. By doing this, you can stop the dishwasher from tipping forward and maintain it in place. Lastly, tidy up the floor and pack away your tools.

Generally Accepted Guidelines for Dishwasher Installation

Choosing the Correct Position Is Crucial
