Changing the Pressure Switch on a Steam Cleaner

Aug 06, 2023, 15:44pm

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

The very hot water vapor is produced from the water put in the tank, thanks to the resistance and the pressure switch.

The pressure switch regulates the pressure in the boiler. There is also a safety device which cuts off the operation of the boiler in the event of excessive pressure inside. This part should be replaced if you notice that:

  • The steam cleaner produces no heat or steam,
  • The steam cleaner spits out liquid water.

The pressure switch is positioned at boiler level, accessible from below the appliance.

Steam cleaners are excellent tools for deep cleaning and sanitizing, utilizing the power of steam to lift dirt and eliminate bacteria. An integral component of a steam cleaner is the pressure switch, a device that monitors and regulates the pressure within the system. Over time, like any other component, the pressure switch may malfunction or wear out, resulting in irregular pressure levels or even rendering your steam cleaner non-functional. In such cases, replacing the pressure switch is usually the most effective solution.

In this article, we’ll walk you through a step-by-step guide on how to replace the pressure switch on a steam cleaner.

Changing the Pressure Switch on a Steam Cleaner

Step 1: Gather the Necessary Tools

Before you start, ensure you have the following tools and the correct replacement part:

  • A new pressure switch compatible with your steam cleaner model
  • A screwdriver
  • Adjustable wrench or pliers
  • Safety goggles and gloves

Step 2: Disconnect the Steam Cleaner from the Power Supply

Before you begin working on your steam cleaner, ensure that it’s turned off and disconnected from the power supply. Safety should always be the first concern when dealing with electrical appliances.

Step 3: Open the Steam Cleaner’s Housing

Use your screwdriver to unscrew and remove the housing of your steam cleaner. This will reveal the internal components, including the pressure switch.

Step 4: Locate the Pressure Switch

The pressure switch is typically located near the water tank or heating element, and it’s often a box-like component with electrical connections. If you have trouble locating it, refer to your steam cleaner’s user manual or look up your model online.

Step 5: Disconnect the Old Pressure Switch

Wearing your safety gloves, disconnect the wires attached to the pressure switch. These connections typically utilize terminals or clips which you can loosen using your screwdriver. Remember to take note of the wiring setup or take a photo to help with the installation of the new switch.

Next, using your wrench or pliers, loosen and remove the old pressure switch.

Step 6: Install the New Pressure Switch

Install the new pressure switch in the same position as the old one. Make sure it’s firmly in place, then reconnect the wires using the notes or photos you took earlier as a guide. Ensure that all connections are secure.

Step 7: Replace the Housing

Once the new pressure switch is installed, it’s time to replace the housing. Place it back onto the unit and secure it with the screws you removed earlier.

Step 8: Test the Steam Cleaner

After you’ve replaced the housing, reconnect the steam cleaner to the power supply and switch it on. The new pressure switch should now be effectively controlling the pressure levels within the system. Test a few cycles to make sure everything is functioning correctly.


Replacing the pressure switch on a steam cleaner can be done independently with the right tools and a helpful guide. However, it’s important to note that this task does involve dealing with electrical components. If you ever feel uncomfortable with the process or encounter difficulties, don’t hesitate to seek help from a professional.

Regular maintenance and timely replacement of components, like the pressure switch, help to extend the life of your steam cleaner and ensure it continues to function efficiently. Remember, safety should always be your primary concern when working with electrical devices. Always ensure the device is unplugged before you begin, and use safety equipment to protect yourself.
