Guide To Installing A New Dishwasher

DIY, How-To,

Are you considering installing a dishwasher to ease the process and save time when cleaning dishes? Seeking professional help translates to accurate and durable results, but it comes at an extra cost. Many homeowners have resorted to YouTube and online tutorials to up their DIY skills. In fact, the majority of homeowners prefer to install household equipment themselves. After buying the right-sized dishwasher and sizing the installation space, follow these tips for expert and accurate installation.

NB: Before installing a new dishwasher, read the manufacturer’s instructions carefully and comprehensively. Locate a properly-ventilated area in your home to fix the dishwasher. Avoid over-tightening the screws when fitting them in the dishwasher. After installing the dishwasher, run a test cycle to ensure it works properly.

Check Installation Requirements

The first thing to do before installing a dishwasher is to check and verify all installation requirements. Confirm if there is enough space for the dishwasher to fit precisely under your kitchen counter. Leave an open space of at least 27 inches in front of the dishwasher for loading and unloading. Check the available power outlet, ensuring it is at least a 120-volt outlet within 45 inches of the dishwasher.

Every dishwasher should be connected to a water supply line within your home, which should be ½ inch in diameter and have a shut-off valve. Similarly, the dishwasher should be connected to a drain line, at least ½ inch in diameter, which should slow download at ¼ inch per foot rate.

Uninstall the Old Dishwater and Prepare the Installation Space

Disconnect the old dishwasher from the power outlet and the water supply line. Carefully unlink the drain link from the dishwasher and remove all the screws holding the dishwasher in place. Now, pull the dishwasher out of its resting area. Comprehensively clean the area underneath the dishwasher where the dishwasher was installed.

Be extra careful when removing the dishwasher from under the counter. Because of its heavy weight, the dishwasher will likely cause injuries if mishandled. Measure the area where the dishwasher will sit before you start the installation process. If you cannot remove the old dishwasher yourself, consult plumbers in Detroit, such as Waterwork Plumbing, to help you professionally remove the old dishwasher.

Install The Water Supply

An important step in installing a dishwasher is to connect it to the water supply line. Locate the water supply line in your kitchen, mostly installed underneath the sink, and then turn off the water supply to the dishwasher. Disconnect the old water supply line from the dishwasher and connect the new one. After successfully connecting the dishwasher to the water supply, turn on the water supply and check for leaks.

For efficiency and durability, use a braided stainless steel water supply and a correct water supply line length. The water supply line should be long enough to reach the dishwasher without being compressed or kinked. You must tighten the connections on your water supply to avoid leaks.

Connect the Dishwasher Drain Hose

When learning how to install a dishwasher on YouTube or through digital tutorials, ensure you properly master the tips on finding and fitting the drain hose for the dishwasher. The drain hose is mostly fitted on the back side of the dishwasher. You need to route it to the sink drain, air gap, or garbage disposal, depending on the amenities available in your home.

Now, connect the drain hose to your kitchen drain location, and utilize a hose clamp to secure the connection tightly. Slope the drain hose downward at a rate of ¼ inch per foot to prevent water backup into the dishwasher. Use the correct dishwasher drain hose length and tighten it properly to avoid leaks.

Properly Connect the Power Cord

Locate the dishwasher power cord, which is mostly found at the back of the equipment. Confirm the condition of the power cord, ensuring it is in perfect working condition. Connect this power cord to the dishwasher, and then plug it into the power outlet. You must ensure the power outlet has the recommended amperage and voltage.

You have to ensure the power cord is not in contact with water. Additionally, avoid overloading the outlet by connecting it to other appliances. Test if the dishwasher is working after connecting the power cord. If it fails to work, consult your electrician to troubleshoot any electrical connection issues. If it is not an electrical connection issue, contact the qualified plumbers at Waterwork Plumbing for help.

Level Up The Dishwasher

Before you round up the dishwasher installation, level it up first. You can easily and quickly do this by opening the dishwasher door and finding the leveling legs. These legs are found on the back and front areas of the equipment. Using a wrench, turn the leveling legs clockwise to raise the dishwashing equipment or counterclockwise to lower it.

Use a level to check the dishwasher’s level from front to back and side to side. Take your time to set the dishwasher at the perfect level to prevent leaks. Once you have leveled your dishwasher, close the door.

Properly Secure Your Dishwasher

The final step in installing a dishwasher is to secure it correctly and tightly to the countertop or cabinet. You need to use the correct type and size of mounting brackets, often supplied with the dishwasher. In cases where the dishwasher does not come with mounting brackets, you might need to buy a safety strap. This is an important fastener for securing dishwashing equipment to the wall.

Place your new dishwasher conveniently away from a walkway when fitting and securing it. After the installation, test the stability of the dishwashing equipment by opening and closing the door several times to test the stability.


Installing a dishwasher can be a relatively easy task, but it is important to follow the instructions carefully to avoid any problems. When you follow these steps, you can ensure that your dishwasher is installed correctly and safely. Every dishwasher has special installation instructions, so read them carefully. You must gather and use the right tools and materials to perfect the installation. If you are not good at DIY installations, you might need to hire professional plumbing specialists to help you with the installation work.
