Dishwasher installation is one of those jobs that you can do yourself with a little patience and careful planning. The first step is to remove the faceplate at the base of the new dishwasher, which will reveal the opening for the inlet and electrical wiring. It’s important to measure this opening’s height, width and depth several times to ensure precision. Rushing this step can lead to a cabinet that doesn’t close correctly or that’s too small for the new dishwasher.
After making sure you have the right size, it’s time to connect the supply lines, drain pipe and power wires. You’ll need a drill with the appropriate bit size, or a hole saw for larger applications, and a screwdriver. It’s also a good idea to have a few extra bits of hardware, like the proper washer and gasket for your specific model. It’s best to install these components before pushing the new dishwasher into place. Trying to fit a too-small or too-large unit can result in cracking or chipping the cabinet.
It’s important to turn off the electricity and water supply at your home’s main panel before you begin. You’ll also want to remove the old dishwasher and disconnect the water supply line, power cord and drain hose. Use a shallow pan or bucket to catch any water that may spill out as you disconnect the lines.
To prevent a messy disaster, place a blanket or an old rug on the floor to protect it from any drips or scratches. You’ll need a few tools, including two adjustable wrenches, a screwdriver, a tape measure and a pair of pliers. You should also have a sponge, bucket and rag for the clean up process. It’s a good idea to read the manual for your new dishwasher before beginning the installation process, as every unit is a little different.
Most units have a 90-degree elbow fitting that attaches to the dishwasher’s water valve, and a drain hose that leads to the sink drain or disposal. These connections are usually compression fittings, and may require joint compound for a leak-free connection.
You can also connect a dishwasher by running the power wire through an electrical box, which will protect you from any potential shocks while you work. Be sure to use the proper 12- or 14-gauge dishwasher electrical wire, as a thinner wire could overheat and create a fire hazard. If you’re not comfortable working with electricity, it’s a good idea to call a licensed electrician. They can help you run a test cycle, and make any necessary electrical or plumbing adjustments. This is especially important if you’re installing your dishwasher in an existing home, where the wiring and pipes may need to be rerouted. It’s also a good idea for homeowners to have their dishwasher installed by licensed tradespeople in order to avoid future problems with the appliance or its installation.
