Got a new dishwasher and want to avoid pricey installation fees? Check out this guide for how to install a dishwasher and do it yourself.
Getting a new dishwasher is exciting, but if the already lofty price doesn’t include installation, you might be left wondering what to do. If you already have some light experience with plumbing and electricity, learning how to install a dishwasher is doable on your own, and you might not need a professional. Make sure you have all the tools you’ll need before starting and read the manufacturer’s instructions for information specific to your new dishwasher, then follow our guide.
Equipment You’ll Need
- Dishwasher connector kit
- Appliance power cord
- Pipe joint compound
- Wire connectors
- Pliers, or an adjustable wrench
1. Take Out Your Old Dishwasher
First, turn off the water supply using the shut-off valve, which is typically under your sink, and turn off the electricity going to your dishwasher at the circuit breaker.
Remove the access panel using your screwdriver, which will usually be somewhere close to the floor.
With your wrench in hand, disconnect the water supply line, and disconnect the old electrical wiring, too.
Remove the drain hose — you may want to place a bowl or some paper towel underneath first, as it’ll probably leak.
Put something down to protect your floor. This could be an old cloth, some plywood, or carboard (like the box from your new washer), then unscrew the brackets that mount the dishwasher to your counter.
Now, the dishwasher can be safely taken out and moved.
2. Prepare the Connections
Tip your new appliance onto its back, so you can access the plumbing and electrical connections easily.
Take off the access panel and follow the instructions on your dishwasher connector kit to attach the elbow onto the water valve.
Remove the old water supply line from the shut-off valve and attach the new one, but don’t hook it up to the dishwasher just yet.
Take out the old drain hose and attach your new one, without connecting it to the appliance yet.
3. Install Your Dishwasher
Tip your new appliance back upright and move it to its spot under the counter.
Now’s the time to connect all the lines: Attach the water supply line to the elbow fitting tightly, then turn your water supply back on to check if there are any leaks. Tighten further if needed.
Referring to the manufacturer instructions, connect both the drain hose and electrical connections.
Head over to your circuit breaker and turn the electricity back on. Test that the dishwasher is functional, and if it’s not, turn the electricity back off and check and adjust your connections again until it’s working properly.
Next, make sure that your dishwasher is level with the above countertop, using a level tool for accuracy. If it’s not flush, you can adjust the leveling legs until it is.
With the included brackets, secure the dishwasher in place, then put the access panel back on.
And with that, you’re done! Having someone install your new appliance for you might be easier, but if you’re looking to do it yourself, we hope that this guide helps you.
