How to Install a New Dishwasher
February 28, 2021
Washing dishes usually isn’t anyone’s favorite chore. That’s why when your dishwasher breaks, you need a new dishwasher installed and operational ASAP. You can install a dishwasher yourself with key tools, knowledge, and careful steps.
Keep in mind that each dishwasher model is different, so you’ll need to refer to the owner’s manual and installation instructions in addition to the steps and tips below.
What tools & materials do you need?
Installing a dishwasher doesn’t require advanced knowledge of plumbing, but it does require familiarity with basic home improvement concepts and tools. Your list of tools should include:
- Dishwasher installation kit that includes a 90-degree fitting, water supply line, and wire connectors
- Pliers
- Adjustable wrenches
- Screwdriver set
- Measuring tape
- Safety glasses
- Flashlight
- Power drill
What’s the Step-by-Step Process?
When you have the tools above secured (and maybe a trusty assistant as well),
- Turn off your kitchen’s water and electricity
Shut off electricity at the circuit breaker, and turn off the water supply at the shut-off valve under the sink.
- Remove your old dishwasher
Removal is a multi-step process. You’ll need the above-mentioned tools to remove the front access panel, disconnect both the old wiring connections in the terminal box and the old water supply line, as well as the drain hose. To avoid a mess and protect your floors, keep a bucket and drop cloth handy to catch any water and gunk. Next, remove the dishwasher’s toe-kick and unscrew the leveling legs. Then, you can pull the old dishwasher out and move it from its current location.
- Clean up the area
There might be quite an accumulation of dust and debris where your dishwasher sat. Clean it out with a wet-dry vac to get a fresh start for your new appliance.
- Get the dishwasher ready for install- and read that manual!
Be sure to read the instruction manual for your new dishwasher so that you understand the process for your specific model. Get your new unit ready by tipping it onto its back. Then remove the front access panel and attach the 90-degree elbow fitting onto the dishwasher water value. Connect the new supply line through the opening between the sink and dishwasher area, then attach the water supply line to the valve. Disconnect the old drain hose, and then connect the new one via the same path as the supply line. Finally, attach the new drain hose to the tailpipe or disposal. With each step, continue to consult your manual.
- Connect your lines & install the trim
Models will vary, but in general, you can expect similar steps: remove the new unit’s toe-kick and flatten all the leveling legs. Then, connect the water supply line and turn on the water so that you can inspect for leaks. Connect the drain hose and then connect the power. Once you’re connected, turn the power back on. Finally, get the unit in place, ensuring it’s flush with cabinet fronts, level, and secure. Again, your manual is key here to a successful installation.
