If it’s time in your household to switch out an old dishwasher for a newer version, you may be considering hiring a professional installer— but wait a minute. While you might need assistance transporting the new and old machines to and from your home, the actual dishwasher installation process isn’t difficult, and you can certainly save yourself some money by completing it yourself. If this sounds like a task in your comfort zone, make sure to read the helpful steps below.
1. Water Supply
Obviously dishwashers need water, so one of the first steps in the installation process is securing this water supply. First, you will need to drill a small hole into the side of the cabinet or wall that houses the hot water valve. Then, thread the copper tubing through the hole and connect the valve to the piping with a nut or ferrule.
After this, you will need to place the water and electrical lines on the floor (ideally using tape) in preparation for their connection with the dishwasher. Measure the distance in between the two paths for these pipes on the underside of the dishwasher, and then place the water and electrical lines separately on the floor at that same distance.
You can finally hook up the water supply once you bring the dishwasher to its new home. You may need to apply a brass elbow to the inlet where the water supply attaches to the dishwasher.
Only second to the water supply, electricity is a vital part of a properly functioning dishwasher. During the installation process, make sure that the clamping bracket holding the wires (in the front of the dishwasher) in place is tight. Then, connect the same-colored wires from the machine and receiving cable using wire nuts.
The last major part to connect is the drain line that will remove any wastewater from the dishwasher. You will need to use a hose clamp to secure the drain tailpiece over the garbage disposal.
4. Finishing Touches
To effectively complete your do-it-yourself dishwasher installation make sure to secure the plumbing strapping to the wall if there is any excess and install any remaining screws to hold the machine in place. Depending on the manufacturer, it may come with specific mounting brackets to attach it to the underside of the counter, and you will need a heavy-duty drill, depending on your countertop, to complete this step.
The last step is simply stepping back and admiring your hard work!
