What Parts Do I Need to Install the Dishwasher?

When you buy a new dishwasher, you may be able to purchase all of the parts you need, but buying these parts individually can be more expensive and stressful. A good installation kit will include all of the necessary parts for installation.

What Do I Need to Do Before Installing a Dishwasher?

Before installing a dishwasher, there are a few things you need to do. 

  • To begin with, you need to find the nearest source of hot water, which will likely be the hot water supply under the sink. 
  • Once you’ve located this source, you need to connect the sink and dishwasher with an angle stop valve, a vertical outlet for the faucet, and a horizontal outlet for the dishwasher
  • You can purchase a long braided wire hose from a home center, plumbing supply house, or hardware store. Also, drill a hole in the cabinet to route the hose through.
  • Next, make sure to set up a clean work area. If possible, place a piece of cardboard or paper on the floor before starting the installation process. Before installing the dishwasher, make sure that its level is positioned properly. You should also connect the dishwasher outlet hose to the cabinet with a loop.
  • Next, prepare the cabinet for the new appliance. Depending on your type of countertop, you may have to install a side-mount dishwasher to avoid a gap. This method is better suited for countertops with more than a quarter-inch gap. 
  • If the countertop is granite, you can also choose a side-mount installation kit. After installing the dishwasher, you should align the brackets and run the drain hose and water supply lines. Once you’ve completed this, you can carefully push the dishwasher into the cabinet.

Can a Normal Person Install a Dishwasher?

If you have experience in plumbing and electrical work, you can install your dishwasher yourself. However, make sure to call a professional if you’re unsure of the process. Many dishwashers are wired directly to the circuit breaker panel. 

If you’re not sure how to connect the power lines, you should call a professional. Otherwise, you can follow this step-by-step installation guide to help you.

Step 1: Shut off the power to the house at the breaker panel. Make sure that all water valves under the sink are closed. 

Step 2: Next, you need to remove the cabinet doors underneath the sink. You will need to open a faucet to drain any standing water

Step 3: Disconnect the electrical supply wires. You can do this by disconnecting them from the box beside the dishwasher.

Step 4: Once you’ve decided on the dishwasher’s dimensions, you’ll need to drill holes in the wall for the dishwasher’s drain and water lines. 

Step 5: After drilling holes and connecting them, reconnect the cabinet to the dishwasher. Make sure to use a plier to attach the 90-degree connector. Make sure that the dishwasher is level and that you don’t bump into any other objects or walls during installation.

Can You Install a Dishwasher Without a Plumber?

Yes! You can install a dishwasher without a plumber but note that power connection is a tricky task for non-electrician DIYers. It is necessary to hard-wire the dishwasher using an NM circuit cable or plug it into a wall outlet. 

In the latter case, you may need a new circuit. Using GFCI protection will also ensure your dishwasher is protected from electricity surges. So, how do you install a dishwasher without a plumber? Here are some helpful tips for doing it yourself.

  • Before installing a dishwasher yourself, it is best to read the installation manual carefully. Make sure you understand the step-by-step procedure and have the appropriate materials. Read the manual carefully and follow the instructions as closely as possible. Do not forget to check the instructions carefully for any mistakes or mishaps.
  • Before attempting to install a new dishwasher, it is also necessary to understand how the water supply line works. The water supply line is typically braided copper or stainless steel. When hooking up a new dishwasher, make sure the copper line is tight and free of bends or cracks. 

If the copper line has already split or disintegrated, you will have to replace it. Flexible stainless steel liners are a good replacement. You can buy them at a hardware store or home center. Be sure to buy enough length of hose and the fittings that match your old line.


Make sure to check reviews to buy the best dishwasher installation kit for the job. This way, you can be sure that you get what you paid for.  

In addition, you’ll have the peace of mind that you’ll have the highest quality dishwasher installation kit in the home.
