Changing the Tank Cap of a Steam Cleaner

Aug 06, 2023, 15:31pm

The steam cleaner is a device used to clean different surfaces, simply with water vapor and without product or detergent. It can be used on glass 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.

It is important that the tank cap remains in good condition: worn or damaged, the water present inside can come out of the device. It is associated with a gasket which seals the tank.

If your device leaks or the tank does not close properly, you will need to replace the cap.

The tank cap is a very simple part to replace, which does not require any tools. The placement of the tank depends on the type of cleaner, but the cap is always above it.

The steam cleaner has become an integral part of home and commercial cleaning due to its ability to clean and sanitize using the power of steam. The performance and safety of the steam cleaner can be significantly influenced by one simple component: the tank cap.

The tank cap serves a crucial role in maintaining pressure within the water tank and preventing accidental spillage of hot water or steam. Over time, the cap might wear out or get damaged, affecting the performance of the cleaner or posing potential safety risks.

In this article, we’ll guide you through the straightforward process of changing the tank cap of a steam cleaner.

Changing the Tank Cap of a Steam Cleaner

Step 1: Gather the Necessary Tools

For this task, you don’t need many tools, but you do need the right replacement part:

  • A new tank cap compatible with your steam cleaner model
  • Safety gloves

Ensure that the replacement cap is suitable for your specific steam cleaner model to guarantee its proper function.

Step 2: Ensure the Steam Cleaner is Safe to Work On

Before you start working on the steam cleaner, ensure it’s safe to do so. Turn off the cleaner and unplug it from the power source. Importantly, make sure the cleaner is cooled down entirely. Opening the tank cap while the cleaner is hot or under pressure can lead to dangerous steam burns.

Step 3: Remove the Old Tank Cap

Once the cleaner is cool, you can proceed to remove the old tank cap. Wearing your safety gloves, twist the cap counterclockwise to unscrew it. If it’s stuck, try gently using a pair of pliers, but be careful not to apply too much force and damage the tank.

Step 4: Inspect the Tank and Cap Threads

Before installing the new cap, it’s a good idea to inspect the threads on both the tank and the cap. Look out for any signs of wear, damage, or debris that might interfere with the seal. If necessary, clean the threads on the tank with a soft cloth.

Step 5: Install the New Tank Cap

Now, it’s time to install the new tank cap. Simply position it correctly over the opening of the tank and twist it clockwise to tighten it. Be careful not to overtighten the cap as it could damage the threads, which might lead to leaks.

Step 6: Test the Installation

With the new cap installed, plug the steam cleaner back into the power source, fill the tank with water, and turn on the device. Monitor it for a few minutes to ensure there are no leaks around the cap, and the cleaner is building pressure and producing steam as it should.


Changing the tank cap of a steam cleaner is a straightforward task that can be done at home with little to no tools. It’s an essential part of maintaining your steam cleaner, ensuring its performance, and preventing potential safety issues.

As always, remember that working with steam cleaners can present potential hazards. Make sure the cleaner is cooled down before you start working on it, and always wear safety gloves to protect your hands. If you ever feel unsure or uncomfortable performing such a task, don’t hesitate to consult a professional. Safety should always be your top priority.
