How To Install A Dishwasher Where There Was None?

Before installing a dishwasher in your kitchen, you should first know both the dimensions of the under-counter space and the cabinet opening. Then prepare the line of hot water with temperature specifications and enough water pressure. With all that done, you’re good to go.

Now let’s dive in and check how you can install your dishwasher like a pro;

01. Do the Preparation Work?

Prepare Dishwasher Location In Kitchen

First, prepare the area where you want to place the dishwasher by ensuring that the floor is perfectly square leveled. Also, confirm if the opening space is of the standard size of the dishwasher- A common opening space of a dishwasher should measure 24 inches deep x 24 inches wide x 34 inches high.

02. Set the Drain up

Where is the existing trap? Is it too far from the dishwasher? If yes, you’ll have to make a dedicated outlet (a vertical pipe connected to the current waste water system).

Also, you’ll need to fit the dishwasher with an air gap, especially if the drain tee is not more than 18 inches from the floor. The air gap introduces air into the drain hose to prevent air from flowing back into the dishwasher.

The process would be pretty straightforward if you’ve fitted the dishwasher next to the disposal.

03. Connect  Power

Let the wiring come into the cabinet to the dishwasher from the rear bottom. You can use one hole for the wiring, waterline, and drain hose. But, ensure that the hole isn’t bigger than 1½ inches. But, if you are using a flexible cord, use a different hole. Ensure that the hardwiring cable comes up along the bottom to the right side.

04. Connect Water Supply

As mentioned earlier, the water supply passes through a hole of about 1½ inches at the bottom of the cabinet. Turn off the water to set under the sink hand shutoff valve.

Locate the dishwasher water connection on the left side and set the water heater’s temperature at 120 degrees Fahrenheit. Also, ensure that the water pressure is set between 20- 120 PSI.

05. Prepare the Dishwasher

First, check the door and adjust the spring tension if need be, and then attach the legs close to where you would install the dishwasher.

06. How to Install a Dishwasher Drain Hose

Attach The Drain Hose

Here is how to install dishwasher drain hose. Connect the drain hose and position the water supply lines and the electric wiring where the dishwasher’s bottom would not catch them. Then, in front of the opening, push the dishwasher carefully and feed the drain hose via the 1½ inch hole you had earlier made.

07. Position the Dishwasher

Position The Dishwasher

Feed the power code and hose supply tube into the sink base at the cabinet back corner hole and push the dishwasher slowly into place. With some inches of the dishwasher left outside, stop and check if anything is kinked. If everything is in order, continue pushing it in.

Ensure that the door edges are at the rear of the cabinet frame. Confirm if the door closes and opens smoothly. Then, level all the dishwasher’s sides by adjusting the leveling legs.

08. Secure the Position

Secure The Position

Secure the dishwasher’s position by aligning the brackets- confirm from the manufacturer’s instructions to do a perfect job.

09. Fix the Water and Power Supply

Fix The Water And Power Supply

The dishwasher would need a supply of hot water to appropriately do the dishes through the wash cycle. And to set it up, you’ve to look for a way of linking it with the current hot waterline.

So, connect the water and power supply through the access panel and then join the drain hose under the sink.

You don’t have to tear the wall or floor to connect a different hot water line for the dishwasher. Instead, you can install a dual shutoff valve or a dual outlet to the existing line.

10. Test the Dishwasher

Test The Dishwasher

Now, it’s time to test your dishwasher. Put its knob on the “rinse only” setting and check if there is any leak.

Summing up, a dishwasher is an excellent investment in your kitchen as it not only saves you time in cleaning up dishes, but it’s also a water and energy-efficient way of cleaning your dishes. Additionally, unexpected items you can clean in your dishwasher in place of dishes. (For example, Refrigerator Drawers and Shelves, Plastic Combs, Hairbrushes, Kitchen Tools Like Scrubbing, Kitchen Brushes, etc.)

Installing a dishwasher like any other appliance may incur additional costs.  On the other hand, Dishwasher installation costs vary depending on dishwasher type and features, electrical modifications, plumbing modifications, flooring repairs, and so on.
