How to Install a New Dishwasher

New Dishwasher

One way to save money on home maintenance is to perform some of the tasks yourself. Kitchen appliance installation can be a great DIY project and learning how to install a new dishwasher can halve the cost of replacement.

Remove the Existing Dishwasher

Before removing the old appliance, make sure you read the installation instructions for the new model. You don’t want to stop in the middle of the project if there are missing parts.

Once you have the required tools and accessories:

  1. Turn off the electricity at the panel.

  2. Turn off the water at the supply valve under the sink.

  3. Remove the front access panel with a screwdriver.

  4. Disconnect the wiring connections in the terminal box.

  5. Disconnect the water supply line from the machine.

  6. Place a bowl or rag under the water connection to catch leaks.

  7. Remove the drain hose from the machine.

  8. Unscrew the brackets that hold the appliance to the countertop and cabinets and remove.

  9. Pull out the old machine and move it out of the way.

  10. Use tape to secure the electrical connect to the floor so you can still access it when the new machine is installed.

Prepare the New Dishwasher Connections

Once the old machine is out of the way, it’s time for the unboxing:

  1. Remove the new appliance from the box, lay it down on its back, and remove the front access panel.

  2. Open the installation kit and attach the 90-degree elbow fitting onto the dishwasher water valve.

  3. Remove the old supply hose and replace with the new one, routing it through the existing access hole.

  4. Remove the old drain hose from the sink drain tailpiece or garbage disposal and replace with the new one.

Install the New Dishwasher

You’re ready to slide the new dishwasher into place and connect it.

  1. Connect the water supply line to the 90-degree elbow and use pliers to tighten. Turn on the water and check for leaks.

  2. Connect the drain hose to the new dishwasher.

  3. Following the manufacturer’s instructions, connect the electrical connections on the dishwasher.

Secure the New Dishwasher

Once the supply, drain, and electrical connections are made, it’s time to install your new dishwasher.

  1. Use a level to make sure the unit is level and use the leveling legs to make adjustments.

  2. Ensure the front of the dishwasher is flush with adjoining cabinets.

  3. Use the brackets included with your new dishwasher to secure it into place and replace the front access panel.
