How to Install a Dishwasher – Step by Step Guide

Whether you are replacing your old dishwasher with an older one or buying a completely new dishwasher, you need to be careful about a few things if you’re heedless about the plumbing skill. Well, this can be a back-breaking task if you are entirely naive about DIY things.

Just stick with us, and we will make a breeze in the installation process. One more thing, if you follow the below simple steps, then installing a dishwasher would hardly take up to 2 hours.

How to Install a Dishwasher?

Make sure you have all the right types of equipment and tools that will make everything easier for you. Here we have a list of the tools that would help you install a dishwasher:

Tools:

  • The instruction manual will guide you about the locations of the bolts, screws, and dimensions of the dishwasher.
  • Take a floor mat or a blanket and place it on the floor to comfortably install it without getting yourself hurt.
  • Safety glasses
  • Gloves
  • Bucket
  • Measuring tape
  • Socket wrench
  • Inlet and outlet hoses
  • Adjustable wrench

Step-by-step Guide:

Step-1: If your old dishwasher is still operating, then run it and remove all the residual water present at the bottom of the dishwasher. Now, don’t directly jump on to the new dishwasher. Shut down the electricity, drain hoses, and water flow of your kitchen. You can do this by using a wrench to cut off conveniently.

Step-2: This is a critical step when you install a dishwasher. You should check for the area of the drainage for the water inlet. Usually, many drainage areas are found to be in the garbage disposal. What does that mean?

The drain hose emerges straight from the dishwasher to the garbage disposal. Apart from that, if you’re looking for an alternative, then you can also directly drain into the water supply pipe, exactly beneath the kitchen sink.

If you feel like there’s no chance of survival, then don’t get down. Try calling a pro plumber, help determine your issue, and sort down your frustration.

Step-3: With the modern dishwashers you have, ensure the properly grounded power cord for them to make it convenient for yourself. Having good hand on reviews and connected with the industry for a long time, we have noticed that some of the dishwashers are found to be directly plugged into a wall rather than on a water outlet. Also, find out the connection of your dishwasher and see if it is appropriately wired or matches with the state’s rules and regulations.

Got muddled with the intricacies of the wires? Well, simply call a plumber, don’t play with the electric wires, and risk yourself to shocks and injuries.

Step-4: Your next step is to dismantle the old dishwasher and say goodbye. You can do that by removing the toe-kick. What’s a toe-kick, and where is it? A toe-kick is rightly placed at the base of the dishwasher, and you can easily remove it with a screwdriver. This would give you access to see the world of the sink.

When you have successfully removed the toe-kick, now you are required to loosen the screws of the leveling legs that exist at each of the four corners. You can unscrew the legs even with your arms and extended wrench.

But, make sure you take a start from the legs that are at the back. So, if you have done this, you have created an adequate space between the countertop and a dishwasher, giving you an easy way to slide the dishwasher out from the former place.

Step-5: Once you have slide-out, you may clean all the dirt, debris, and grime present for months or even years. After cleaning it thoroughly, move on to the next step.

Step-6: Feeling happy? As you’re completely done with the cumbersome task of electrician and plumbing but here’s another task for you, and that is to install a new dishwasher that you’ve just bought it. Now, unpack the box of the dishwasher, and you’re good to go with the installation process.

Step-7: After unboxing the box, the first thing that will get your attention is the instruction manual placed at the front. To make things easy for you, read the manual thoroughly until you get all the points and you’re ready to install.

It includes all the things that you need to install and what things to consider. It’s just like reading a recipe book before preparing for a delicious meal. You have the tools. All you need is execution.

Step-8: When you have a manual in your hand, what else do you need? The manual will guide you from scratch and will help you successfully install a dishwasher along with the steps mentioned above.

Call a Pro:

Couldn’t install a dishwasher properly or facing some issues now and then? Worry, no more and don’t hesitate in contacting a plumber, handymen, or technicians that will make it all happen for you within a matter of minutes.

But, if you know about the do’s and don them of plumbing skills, you may not need a technician. Also, to make a long-lasting installation, we recommend you to call a professional, get it fixed, and stay worry-free for years to come.

When installing a dishwasher, you must keep in mind that the dishwasher hose plays a vital part in installing it successfully. The hose needs to be perfectly placed to drain the water and to do its job effectively. If your sink is embedded with the garbage disposal, then connect the hose to the dishwasher water outlet on the disposal housing.

Unfortunately, if you had not purchased a dishwasher before then, you might have to detach the knockout plug for the water flow into the disposal housing. Moreover, if you haven’t installed the garbage disposal, you must connect the hose directly to the discharge port on the drain assembly.
