How to Replace the Steam Generator in Your Laundry Closet

If your laundry closet’s steam generator has stopped working, don’t worry, replacing it yourself is easier than you might think. With just a few tools and a little time, you can swap out the old unit and get your clothes steaming fresh again in no time. Here’s how to replace the steam generator in your laundry closet step by step.

The information in this article may not apply to your specific appliance model. We recommend consulting your manufacturer’s documentation or contact us with any questions.

Why the Steam Generator Matters

The steam generator heats water and converts it into steam on demand. This hot vapor is then circulated through the chamber to freshen and relax your clothes. When it fails, you may notice:

• No steam output during cycles
• Inconsistent or weak steam
• Error codes or warning lights
• Strange noises during operation
• Water leaking from inside the closet

These symptoms usually mean the generator has become clogged, corroded, or electrically faulty and needs to be replaced.

Tools and Parts You’ll Need

Before you begin, gather the following:

• Replacement steam generator that matches your model
• Phillips and flathead screwdrivers
• Needle-nose pliers
• Wrench set
• Small towel or sponge (for any water spills)
• Clean cloths to wipe down parts

Be sure to purchase the correct replacement steam generator for your exact steam closet model. The model number is usually found in your owner’s manual or on a label inside the unit.

Safety First

Always unplug your steam closet from the power outlet before starting. If your model is hardwired, turn off the circuit breaker. Let the appliance cool completely if it has been used recently to avoid burns.

Step 1: Access the Steam Generator

The steam generator is usually located behind a panel at the base or rear of the steam closet.

1. Unplug the unit and move it away from the wall, if needed, to access the back.
2. Remove any screws securing the back or lower panel.
3. Carefully lift off the panel and set it aside, keeping track of the screws.

You should now see the internal parts of the steam closet, including the water tank, electrical connections, and steam generator.

Step 2: Disconnect the Water Supply

Before removing the steam generator, disconnect the water line that feeds it.

1. Locate the water hose connected to the steam generator.
2. Use a wrench or pliers to loosen the hose fitting.
3. Have a towel handy to catch any residual water that drips out.

Once disconnected, set the hose aside.

Step 3: Disconnect the Electrical Connections

The steam generator will also have one or more electrical connectors. These supply power to the heating element inside.

1. Note the position of each wire or take a quick photo for reference.
2. Gently pull the connectors free or unscrew them as needed.
3. Make sure no wires are pinched or damaged.

Step 4: Remove the Old Steam Generator

With the water and electrical connections detached, the generator itself is usually held in place with mounting screws or brackets.

1. Locate and remove the screws or bolts securing the steam generator.
2. Carefully slide the steam generator out of its housing.
3. Set it aside on a towel to avoid making a mess.

Take this opportunity to inspect the housing area for debris, mineral deposits, or leaks. Wipe everything down with a clean cloth.

Step 5: Install the New Steam Generator

Take your replacement steam generator and position it where the old one was installed.

1. Align it properly with the mounting holes and brackets.
2. Secure it with the screws or bolts you removed earlier.
3. Double-check that it sits firmly and does not wobble.

Step 6: Reconnect the Water Line

Reattach the water supply hose to the inlet on the new steam generator.

1. Hand-tighten the fitting first, then snug it with a wrench.
2. Do not overtighten, which could damage the fitting or cause leaks.
3. Wipe away any water and make sure the connection is clean and secure.

Step 7: Reconnect the Electrical Wires

Using your photo or notes as a guide, reconnect the electrical wires to the new steam generator.

1. Make sure each wire is fully seated on the correct terminal.
2. Tug gently to confirm the connectors are secure.
3. Double-check that no wires are loose or touching other parts.

Step 8: Reassemble the Panels

Once the new generator is installed and everything is reconnected:

1. Replace the back or lower panel of the steam closet.
2. Secure it with the screws you removed earlier.
3. Move the steam closet back into position, if you moved it.

Step 9: Test the Steam Closet

Plug the steam closet back in and turn it on. Run a short cycle to test the new steam generator. If everything works properly, you’re done.
