Safety Precautions

Before you begin, safety should be your top priority. Make sure to turn off the power and water supply to avoid accidents. Additionally, wear appropriate safety gear, such as gloves and safety glasses.

Gather Your Tools and Materials

To start the installation, gather the necessary tools and materials. You’ll likely need an adjustable wrench, screwdrivers, a drill, pliers, a hose clamp, and a new dishwasher installation kit.

Turn Off Power and Water

Before you proceed, turn off the power and water supply to the dishwasher and garbage disposal. This is crucial to ensure your safety during the installation process.

Remove the Old Connections

If you’re replacing an old dishwasher, disconnect the existing drain hose and water supply line. Remove any mounting brackets as well.

Install the Air Gap (if required)

In some areas, building codes necessitate the use of an air gap to prevent wastewater from flowing back into the dishwasher. Install the air gap on the sink’s countertop or the sink itself.

Connect the Drain Hose

Attach the new drain hose to the dishwasher’s drain outlet. Secure it with a hose clamp to prevent leaks. Connect the other end of the hose to the garbage disposal unit’s dishwasher inlet.

Connect the Water Supply Line

Attach the water supply line to the dishwasher’s water inlet valve. Make sure the connections are secure to prevent leaks.

Secure the Dishwasher in Place

Carefully slide the dishwasher into its designated space, ensuring it’s level and secure. Use mounting brackets to secure it to the underside of the countertop.

Test for Leaks

Turn on the water supply and check for any leaks around the connections. If you spot any, tighten the connections as needed.

Reconnect Power and Test the Dishwasher

Once you’re certain there are no leaks, reconnect the power supply and turn on the dishwasher. Run a test cycle to ensure everything is functioning correctly.
