Changing the Solenoid Valve of a Steam Cleaner

Aug 06, 2023, 15:19pm

The steam cleaner is a device used to clean different surfaces, simply with water vapor and without product or detergent. It cleans windows or hard floors, as well as rugs and carpets. The surface to be cleaned influences the type of cleaner: sled, hand or broom.

Very hot water vapor is produced from the water put in the tank, thanks to the resistance and the pressure switch, when the solenoid valve is open. The solenoid valve is a part that serves as an electric valve, controlled by the trigger of the steam cleaner. When this trigger is pressed, the valve can open and allow steam to pass.

This part should be replaced if you notice that:

  • The steam cleaner produces no heat or steam,
  • The steam cleaner spits out liquid water.
  • Nothing comes out of the steam cleaner.

The solenoid valve is located at the level of the boiler, accessible from below the appliance. It is close to the pressure switch and the resistor.

A steam cleaner is an efficient and reliable tool, highly valued for its ability to clean and sanitize a wide variety of surfaces. It operates on the principle of generating pressurized steam that is forced out through a cleaning nozzle. One crucial component that aids in this process is the solenoid valve.

The solenoid valve regulates the flow of water from the reservoir to the heating chamber, where the water is turned into steam. Over time, this valve may wear out or become defective, affecting the operation of your steam cleaner. In such cases, replacing the solenoid valve is the optimal solution.

This article provides a step-by-step guide on how to change the solenoid valve of a steam cleaner.

Changing the Solenoid Valve of a Steam Cleaner

Step 1: Gather Necessary Tools

Before you begin, gather the following tools and materials:

  • A new solenoid valve compatible with your steam cleaner model
  • A screwdriver (usually a Phillips or flat-head, depending on your model)
  • An adjustable wrench
  • Safety goggles and gloves

Make sure you have all these tools at hand before you start the replacement process.

Step 2: Disconnect the Steam Cleaner from the Power Supply

Before you start working on any electrical device, it’s important to disconnect it from the power supply for safety reasons. Ensure that the steam cleaner is turned off and unplugged.

Step 3: Open the Steam Cleaner’s Housing

Locate the screws securing the housing of your steam cleaner and carefully remove them using your screwdriver. Gently lift off the housing to reveal the internal components of the machine.

Step 4: Locate the Solenoid Valve

Within the internal components, identify the solenoid valve. It’s generally a cylindrical or box-like component connected to several wires and tubes. It’s usually located near the water tank or the boiler. If you’re struggling to locate it, refer to your steam cleaner’s user manual.

Step 5: Disconnect the Solenoid Valve

Once you’ve identified the solenoid valve, the next step is to disconnect it. Start by removing the wires connected to the valve. Use your screwdriver to loosen any terminals, and carefully disconnect the wires.

Next, use the adjustable wrench to disconnect the tubes leading to and from the solenoid valve. Take note of which tube goes where, as you’ll need this information when installing the new valve.

Step 6: Remove the Old Solenoid Valve

Now that everything is disconnected, remove the old solenoid valve from the unit. It might be held in place by screws, clips, or brackets, so use your screwdriver or wrench as needed.

Step 7: Install the New Solenoid Valve

Install the new solenoid valve in the same position as the old one. Make sure it’s secure. Reconnect the tubes and wires you previously disconnected, ensuring that everything goes back to its original place.

Step 8: Close the Housing

With the new valve in place, replace the housing cover and secure it with the screws you removed earlier.

Step 9: Test the Steam Cleaner

Plug your steam cleaner back into the power source and turn it on to test it. The new solenoid valve should now be working, and your steam cleaner should be functioning as it should.


Changing the solenoid valve of a steam cleaner can seem like a daunting task, but with the right tools and instructions, it’s something that can be done at home. By following the steps in this guide, you should be able to successfully replace the solenoid valve of your steam cleaner.

However, if you encounter any difficulties or if you’re not confident in carrying out the process yourself, always consider seeking professional help. It’s crucial to prioritize safety when working with electrical appliances.
