So you just bought yourself a new dishwasher, now what? Installing it may not be as simple as you think. There are several things to consider before your install the dishwasher. Such as location, electrical hookup, and drain line installation or connection. With these things in mind, you can easily install any dishwasher without having any problems.
Location matters most when installing any appliance in your home. Consider the following factors before choosing a location for your dishwasher:
- Dishwasher size (height and width)
- Electrical power availability (if moving or placing another outlet is needed)
- Possible plumbing hookup needs (plumbing drain line or connection)
- Preferred location for ease of use and access to dishes.
- Enough surrounding space for moving the dishwasher in and out, as well as around.
If properly installed by a professional, most any appliance can be done with little effort on your part. With some basic knowledge on wiring and plumbing, you can install a dishwasher quickly and easily. However, be sure to contact our professionals if you have any questions or concerns.
When selecting a location for your dishwasher, you'll need to consider electrical power availability. If using an existing outlet, determine its amperage and voltage rating. Your appliance should have both ratings listed on the nameplate sticker located on the inside of the door or on the back of the washer. Using an outlet with amperage lower than the appliance's rating can cause overheating or tripped circuit breakers. If available, use a 20A dedicated circuit breaker on your home electrical panel.
Before installing the dishwasher, bear in mind that some older homes may have older wiring systems, therefore having to run new wire. Your wiring system is important to consider and one of the important things to keep in mind before installing your dishwasher. Determine the location of the dishwasher, choose an open electrical junction box within 4' being able to provide at least 3 wire splices. You'll need a ground wire with a pigtail attached, a white wire for neutral, and a black or red wire for power. If new wiring is needed, contact your local electrician to have this completed.
Offering more than one location for your dishwasher may seem confusing, but it can be done. You'll need to consider plumbing hookup or drain line as well as electrical outlets and power availability before deciding where to place your dishwasher. If you plan to install the dishwasher on a pedestal base (casters), then leveling is the next biggest factor to consider. The dishwasher will need at least 3" of space under the countertop for proper drainage and ventilation.
Plumbing hookup is another crucial factor when installing a dishwasher. They come in two different styles: P-trap connection or drain line installation. If using a P-trap, you'll need 1/2" copper piping, Teflon tape, and a P-trap or strainer. Determine your dishwasher's height (front to back) which will determine the correct P-trap size needed. If installing with a drain line, you'll need 1/2" plastic tubing for proper drainage. If using new plumbing, be sure to contact your local plumber to have the lines installed.
Once you've determined a good location, wiring, and plumbing hookup for your dishwasher, it's time to install. These are basic steps and important things to keep in mind before installing your dishwasher. From there follow these basic steps:
1. Turn off the power at your home electrical panel or fuse box.
2. Apply a bead of silicone caulk on the back of the dishwasher and place it against the countertop.
3. Secure dishwasher in place by using screws provided with the appliance (if applicable) or with appropriate hardware for your brand and model of dishwasher.
4. Connect the water supply line to the inlet valve located at bottom right-hand side near floor level and left-hand side in the rear.
5. Follow installation instructions for drain line (if needed)
6. Connect the drain line to p-trap (if using one).
7. Turn on water supply and electrical power at the home panel or fuse box.
8. Run your dishwasher's wash cycle, allowing the machine to fill completely before starting the pump assembly (if equipped).
9. Check for leaks at all supply connections and drain line connection at p-trap.
