- User manual for your washer-dryer

- Screwdriver

- Adjustable wrench

- Pliers

- Teflon tape

- Spirit level

- Bucket

- Old towels (to soak up any leaks)

Judi Kutner explains, "Washer-dryer combos are good in some situations but imperfect. They save much space, which is a big deal for people in apartments or smaller homes."

"That said, the drying part is where most people feel let down. The machine can usually only dry about half of what it can wash, so you either split loads or air-dry some of your clothes. Separate machines tend to perform better overall."

We suggest you don't tackle the installation yourself but accept an installation from the manufacturers or resellers.

However, before installation, educating yourself about how washer-dryers work and how to use them is wise. This can help you understand some potential pitfalls and limitations.

This guide will provide expert advice, best practices, techniques, and solutions for installing your washer-dryer, as well as step-by-step instructions for getting the best results from your machine.

First, double-check the manufacturer’s guidelines for specific instructions and installation advice. As a rule of thumb, this is the best place to begin.

Manufacturer Installation

It's important to note that most manufacturers will advise that the machine be installed by professionals insured to perform installations for the said machine.

It's vital to understand this advice, as it's likely that if you decide to install the model yourself, the warranty will be immediately void. This could leave you in a difficult position later on if your machine breaks down or turns out to be faulty.

We would always advocate following the guidelines and advice of the manufacturers, especially in this case.

We do advise that you agree to expert installation from the manufacturers.

However, this feature will still be beneficial for you to help you prepare what you need in the space for the washer-dryer, and it may potentially save you time and money, as you can get prepared ahead of your machine installation.

AO expert Gwil Snook says, " We always recommend not installing the appliance yourself, as it can void your warranty. Instead, use services provided by retailer professionals."

How to install a washer-dryer combo: Step-by-step guide

1. Prepare a space for the machine

Check that where you intend to position your washer-dryer combo is suitable for your machine, and consider the following:

1. Is there a nearby hot and cold water supply and drainage?

2. Is there a power outlet? Most models require a 120V or 240V outlet.

3. Ensure proper ventilation and space for the machine to vibrate and move a little.

4. Measure the space to ensure adequate room for the washer-dryer.

Judi Kutner explains, "Installation isn’t complicated but has to be done right. The machine should be near water and drainage with good ventilation."

Expert Joy Aumann asserts: "Installing a washer-dryer is straightforward but needs attention to detail. Ensure the space is big enough and has hot and cold water access. A good drainage setup is crucial, so securely attach the hose to avoid leaks."

Gwil Snook says, "When installing your washer-dryer, ensure access to a cold-water supply, a waste hose connected nearby, and a power outlet."

All our experts agree that your washer-dryer must be near a hot and cold water supply, a drain, and a power outlet.

2. Check the area is near a water supply and drain

As our experts advise, ensure that your washer-dryer is located close to a hot and cold water supply and drain and that these are in good working order.

3. Check the area is near an electrical outlet

Another crucial must-have our experts explained is to ensure that the intended space for your washer-dryer is near a power outlet.

It's also advisable to check that your power outlet is safe and in good working condition.

4. Connect to the water supply and test for leaks

Connect the hot and cold water supply hoses for the unit to the water inlets on the rear of the washer-dryer. Then, attach the other end of the hoses to the water supply valves.

Using a wrench, secure the hose at both ends. Tighten comfortably but not too tightly to avoid pressing on the machine.

Switch on the water supply and check for leaks. If necessary, secure any threads with Teflon tape. If necessary, use a bucket and towels.

5. Connect the drain hose

Place the drain hose in position and secure it as you insert it into the sink, wall drain, or standpipe.

The drain hose should be at the height required for your particular washer-dryer.

Siphoning issues may result from the drain hose not meeting the required height.

Judi Kutner explains: "Hoses need to be attached securely to avoid leaks."

6. Connect to power

Connect the power and plug the unit into a safe and grounded electrical outlet.

We advise against utilizing extension cords or power strips.

Ensure the washer-dryer unit is compatible with your home's electricity system and power supply.

Judi Kutner explains, "The power outlet should match the machine’s requirements. Skipping these details can lead to trouble later."

7. Ensure machine is level and stable

Ensure that the machine is level and stable in your desired location so that it can run safely and minimize the possibility of damage.

Adjust the base and feet of the washer-dryer to ensure the machine is level. Use a spirit level to test this. Tighten the feet of the unit to ensure it is stable and secure.

Joy Aumann asserts, "Double-check that the machine is perfectly level. This helps prevent noisy vibrations during cycles. Take time setting it up, and it’ll work efficiently for years."

8. Run a test cycle

Run a complete test cycle for your washer-dryer combo.

Check that the machine performs a complete wash and dry cycle. Ensure there are no leaks and the washer-dryer is in full working order. Also, look out for any strange or unexpected noises, vibrations, or movement.

If you are concerned, contact the technician to look at your machine.

How to install a washer-dryer combo: FAQs

Should I install a washer-dryer myself?

Our advice is to follow the manufacturers' guidelines for installing your machine. Generally, this means opting for manufacturer installation from insured technicians, as installing the washer-dryer yourself can result in losing your warranty.

As AO expert Gwil Snook asserts above, "We always recommend not installing the appliance yourself, as it can void your warranty. Instead, use services provided by retailer professionals."

What should I consider for washer-dryer installation?

Before installation, it's key to consider where you intend to place your washer-dryer combo. Is there space in your kitchen, utility room, garage, or other room to instruct the technicians to install your machine?

You must ensure that the floor is level in the intended area and that the washer-dryer's intended location is close to a water supply, drain, and power outlet.

Be sure all your plug sockets are safe and in whole working order.

Be advised that during installation, you will likely need to be present to provide the technicians with information on the location of your home circuit breaker or similar device.

If you could read the user manual and instructions for your machine before installation, that would be ideal. You will likely be able to find this on the manufacturer's website.

If you have any questions before installation, ask the manufacturer or reseller you purchased from.

Final thoughts

Installing a washer-dryer might sound like a daunting task. For the reasons we just explored, you should leave this work to the professionals, especially if doing it yourself would result in a loss of your warranty. It's simply not worth the hassle.

You should opt for a manufacturer's installation, or if that isn't possible, contact a trusted professional technician for help.

Educate yourself on the above steps for washer-dryer installation and follow the guidelines to ensure your home is suitable for your purchased model.

We would advise that you research these aspects before you buy. Discover how much a washer-dryer will cost in our helpful guide.
