Is Installing a Washing Machine a DIY-Friendly Project?

Washing machines are one of the more DIY-friendly installations. If your laundry area already has the proper hookups and you feel confident with basic home maintenance tasks, the installation is usually straightforward.

However, that doesn’t mean it’s completely risk-free, and it’s important to understand the process before getting started so you avoid installation mistakes.

When You Can DIY It

Before starting a DIY installation, there are a few things you should check first. You can still install your washing machine if your situation doesn't match the conditions below, but the job will likely be more difficult and require additional steps and tools.

1. You Have Existing Hookups or Are Replacing an Existing Machine

DIY installation is easiest when your laundry area already has the necessary hookups. This is often the case when you're replacing an existing washing machine, but any laundry area with compatible hookups is a good candidate for DIY installation.

Make sure you have:

  • Hot and cold water supply connections
  • A compatible drain connection
  • A properly grounded electrical outlet
  • Hookups in good condition with no leaks, corrosion, or visible damage

2. You're Comfortable with Basic Home Maintenance

Installing a washing machine doesn't require advanced plumbing or electrical work, but you should be comfortable with a few basic DIY tasks.

Before getting started, make sure you can confidently:

  • Move a heavy appliance
  • Connect the water supply hoses correctly
  • Check for leaks after installation
  • Level the washing machine

3. You Have the Right Tools and Assistance

Having the right tools and an extra set of hands can make the installation safer and easier.

Make sure you have:

  • Pliers
  • A level
  • An adjustable wrench
  • A bucket and towels for spills
  • A second person to help move and position the washing machine

How to Install a Washing Machine

The exact process of installing a washing machine varies depending on the unit type and manufacturer, but most installations follow these general steps:

Before bringing in your new washer, make sure the installation area is ready.

  • Disconnect and remove the old washing machine, if applicable.
  • Turn off the hot and cold water supply valves.
  • Inspect the water supply valves, drain connection, and electrical outlet for signs of damage or leaks.
  • Clean the installation area and confirm there is enough room for the new washer.
  • Check the manufacturer's installation instructions for any recommended clearance requirements around the appliance.

If you discover damaged plumbing, an improper drain, or electrical issues, you will need to have them repaired before installing the new appliance.

Washing machines are heavy appliances that typically weigh between 150 and 250 pounds. (1) Moving one improperly can result in personal injury, damage to your floors, or damage to the appliance itself.

  • Use an appliance dolly whenever possible.
  • Have at least one other person help move the washer.
  • Leave enough space behind the machine to connect the water supply hoses, drain hose, and power cord.
  • Make sure the hoses and power cord won't be pinched or kinked when you slide the washer into place.

Most front-loading washing machines include shipping bolts that hold the drum in place during transportation.

  • Locate and remove every shipping bolt according to the manufacturer's instructions.
  • Install the supplied plastic caps over the bolt holes, if applicable.
  • Save the shipping bolts in case the washer needs to be transported again.

Never operate the washer with the shipping bolts still installed. Doing so can damage the suspension system, drum, and other internal components.

Next, connect the hot and cold water supply hoses.

  • Connect each hose to the correct hot and cold water inlet.
  • Confirm the rubber washers are installed inside each hose fitting.
  • Hand-tighten the fittings before using a wrench.
  • Avoid overtightening, which can damage the fittings.

Once the hoses are connected, slowly open the hot and cold water supply valves. Check the hose connections for any immediate leaks before moving on to the next step.

Proper drain hose installation helps prevent leaks and drainage problems.

  • Secure the drain hose in the standpipe or laundry sink.
  • Position the drain hose at the height specified by the manufacturer.
  • Make sure the hose isn't kinked or pushed too far into the drain.

An improperly installed drain hose can cause poor drainage or allow water to siphon back into the machine.

Once all plumbing connections have been completed, plug the washer into the appropriate electrical outlet.

  • Plug the washer directly into a properly grounded outlet.
  • Never use an extension cord, power strip, or adapter.
  • Make sure the outlet, plug, and surrounding area are completely dry before connecting power.

If the outlet doesn't meet the manufacturer's electrical requirements, stop the installation and contact a licensed electrician.

A properly leveled washer operates more quietly and helps reduce unnecessary wear.

  • Adjust the leveling feet until the machine sits evenly.
  • Check the level from side to side and front to back.
  • Press on each corner to make sure the washer doesn't rock.

Before washing your first load, run an empty test cycle to make sure everything is working properly.

During the test cycle, check for:

  • Water leaks around the supply hoses.
  • Proper drainage.
  • Excessive vibration or movement.
  • Unusual noises or error messages.

If you notice leaks, excessive vibration, or other problems, stop using the washer until the issue has been corrected.

When You Should Call in a Professional

Hiring a professional is often the safer and more cost-effective choice if your installation requires any of the following:

  • New Plumbing Connections: If you need new water supply lines, shutoff valves, or any other plumbing connections installed, it's best to contact a plumber. They have the tools and expertise to install the machine correctly, test for leaks, and ensure everything meets local plumbing codes.
  • Drain Modifications: If your drain setup needs to be modified or isn't functioning properly, it's best to correct those issues before installing your washer. A professional can ensure your drainage system is properly set up to prevent backups, leaks, and drainage problems.
  • Electrical Work: If your outlet is outdated, damaged, improperly grounded, or doesn't meet the manufacturer's electrical requirements, a licensed electrician can make sure it is safe to use. This is especially important for a laundry area where water is present.
  • Moving the Washer to a New Location: If you plan to install a washer in a new room, you'll likely need new plumbing, drainage, and electrical connections. Because these systems often need to be installed from scratch, the project is much more involved than replacing an existing washer.

Even if your installation doesn't require major plumbing or electrical work, there are still situations where hiring a professional can be the better choice:

  • You Live in an Older Home: Older homes may have hidden plumbing issues, such as leaks, corrosion, or worn shutoff valves. These issues should be identified and addressed before connecting a new washing machine.
  • You Want Peace of Mind: Professional installation helps reduce the risk of leaks and water damage, protects your manufacturer's warranty, and ensures your washer is ready to use.
