Steps to Install a Dishwasher for the First Time
Installing a dishwasher is not as difficult as it may seem. Here, we'll walk through the process and share some important tips.
1. Switch Off the Power and Water
The first step is always to turn off the power and hot water supply lines at their source before you start any work on them. This would prevent damage if they were accidentally turned on while you're working on them.
2. Decide where to put it
The next step is to determine where you want your new dishwasher to go with other appliances in your kitchen. Again, you may need more space than what's available at first glance, so be sure to take measurements beforehand so nothing gets in your way later on down the line.
3. Read the instructions carefully
Now that you've got all these things, it's time to read through your installation instructions thoroughly before starting anything else! They'll tell you exactly what needs to be done so there aren't any surprises along the way (which could lead to costly mistakes).
4. Make sure to connect the drain line
You can open up the existing drain line and connect it to your new dishwasher's drain pump. The easiest way to do this is by using an elbow fitting pre-assembled with tubing attached to it. Then, attach your new dishwasher's drain line to this fitting. Once everything is connected, use the plumber's tape on all connections to prevent leaks.
5. Connect the water line and dishwasher elbow together
To do this, place them over each other, forming a kind of "Y" shape, with one end going into your sink and another into your new dishwasher. Then, secure them with a plumber's tape or another type of sealant that works well against leaks in both pipes (if possible).
6. Tighten the connections securely
You have two options: hardwiring or plugging in to connect the dishwasher to a power source. If you're installing a new dishwasher, the instructions will tell you what kind of connection is needed and how to do it. For an existing installation, you may need to consult an electrician to determine whether or not you can do it yourself.
7. Reconnect the Drain Hose
You'll need a drill and a pair of pliers to install your new dishwasher. First, remove the old hose from its connection point on your sink by loosening it with a wrench or socket. Then, fit the new drain hose onto your sink's drain line. Secure it firmly so it won't fall off. Once everything is connected correctly, turn on the water supply, so it flows through and into your sink's drain line.
8. Test the dishwasher to make sure it is functioning properly
Once you've reconnected your dishwasher's drain hose, it's time to test your new unit. Use a wet rag or paper towels and run them through each cycle to ensure they work correctly. Once satisfied with their functionality, secure them with screws or brackets as needed, so they don't fall off during use.
Things you need to know before installing a dishwasher
Before starting the installation process, you'll need to have some information. Here are some things to keep in mind:
- What type of dishwasher you're installing?
- The size of the dishwasher and its location in your kitchen cabinetry.
- The electrical requirements for this particular model and whether or not it can be hardwired or plugged into an outlet instead.
- How much space is available (or needed) at this point in time—and are there any obstructions that could get in the way during installation?
How much does Home Depot charge to install a dishwasher?
The average cost for installing a dishwasher runs about $200, with most homeowners spending between $185 and $225 for just the labor. But if you need modifications to your plumbing, wiring, or countertops, the price could go up to $485.
As with most things, the cost of having your dishwasher installed will depend on what type of appliance you choose. Some models are more challenging to install than others, so that Home Depot will adjust its pricing based on this factor. Most stores will also require you to buy through them to receive installation services, which may add another cost to your purchase.
To determine how much it might cost for Home Depot to install your new dishwasher, take into consideration:
- The size and price of the model you're looking at
- If the installation is not included in the purchase price
Can you put a countertop dishwasher in a cabinet?
Yes, you can put a countertop dishwasher in a cabinet. However, it's more expensive to install one than a freestanding model.
Your options for installing an integrated dishwasher vary depending on the type of cabinet or cupboard that is available:
- You can install an integrated under-counter dishwasher under your sink. This option is best if you have limited counter space or don't want to use any extra space for washing dishes.
- You can install an integrated wall-mounted dishwasher in your kitchen cabinet (or another wall). It isn't easy to place these correctly because they need to be level with the rest of the cabinets around them and balanced so they aren't too heavy on one side or another when they swing open while being used (which could cause them to break).
- To match the rest of your cabinets' hardware and blend your appliance doors in with the rest of your cabinets, you might want to install appliance pulls. Appliance pulls are long handles commonly used on appliances with wood paneling, such as refrigerators and dishwashers.
Can I use an existing cupboard door for an integrated dishwasher?
Yes! You can use an existing cupboard door for your integrated dishwasher. It's a good idea to check the depth of your cupboard door before you begin installation so that you know if it will be long enough when closed to cover your new appliance. You may need to trim down some of its sides if it is not wide enough.
You also need to make sure that the door has a flat surface on top and bottom because most integrated dishwashers require mounting onto studs (or directly into drywall). To prevent sagging over time and keep the surfaces level, you should use studs to support them.
Why are built-in dishwashers more expensive than freestanding?
It may cost you extra money to install a dishwasher, as you will need to hire a plumber to connect water lines. Modifications can incur more costs if your kitchen cabinetry doesn't have an opening.
When you're looking at the cost of installing a dishwasher, there are many factors that you must take into account. The work involved in installing a built-in dishwasher is more than just putting one part next to another. You have to factor in all of the materials and labor needed for:
- If you're planning to add an electrical outlet to your home, have a qualified electrician do the work.
- If you do not already have plumbing installed in your home, you may need to install plumbing.
- Cabinetry (if your home doesn't have any cabinets)
