As a supplier of wall mounted pressure washers, I understand the importance of maintaining these powerful cleaning tools to ensure their optimal performance. One crucial aspect of maintenance is cleaning the filter regularly. In this blog post, I'll share a detailed guide on how to clean the filter of a wall mounted pressure washer, including the reasons for cleaning, the necessary tools, and a step-by-step process.

Why Clean the Filter?

The filter in a wall mounted pressure washer plays a vital role in protecting the pump and other internal components. It captures dirt, debris, and sediment from the water supply before they can enter the pump. Over time, the filter can become clogged with these particles, which can lead to several problems:

  1. Reduced water flow: A clogged filter restricts the flow of water into the pressure washer, reducing its cleaning power.
  2. Increased wear and tear: When the pump has to work harder to draw water through a clogged filter, it can lead to increased wear and tear on the pump and other components, potentially shortening their lifespan.
  3. Higher energy consumption: The pressure washer may consume more energy to compensate for the reduced water flow, leading to higher operating costs.

By cleaning the filter regularly, you can prevent these issues and ensure that your wall mounted pressure washer continues to operate efficiently and effectively.

Tools You'll Need

Before you start cleaning the filter, gather the following tools:

  1. A pair of pliers
  2. A bucket
  3. A soft brush or toothbrush
  4. Mild detergent or filter cleaner solution
  5. Clean water

Step-by-Step Guide to Cleaning the Filter

Follow these steps to clean the filter of your wall mounted pressure washer:

Step 1: Turn Off the Pressure Washer

Before performing any maintenance on your pressure washer, it's essential to turn off the power supply and disconnect the water source. This will prevent any accidental start-up and ensure your safety.

Step 2: Locate the Filter

The filter is typically located between the water inlet and the pump. Refer to your pressure washer's user manual to find the exact location of the filter.

Step 3: Remove the Filter

Using a pair of pliers, carefully loosen and remove the filter housing. Be cautious not to damage the housing or any other components. Once the housing is removed, take out the filter.

Step 4: Inspect the Filter

Examine the filter for any signs of damage or excessive wear. If the filter is torn or damaged beyond repair, it should be replaced with a new one.

Step 5: Soak the Filter

Fill a bucket with clean water and add a small amount of mild detergent or filter cleaner solution. Submerge the filter in the solution and let it soak for about 15-20 minutes. This will help to loosen and dissolve any dirt and debris trapped in the filter.

Step 6: Clean the Filter

After soaking, use a soft brush or toothbrush to gently scrub the filter. Pay special attention to the areas with heavy dirt buildup. Be careful not to scrub too hard, as this could damage the filter. Rinse the filter thoroughly under running water to remove all the dirt and cleaning solution.

Step 7: Dry the Filter

Shake the filter gently to remove any excess water. Then, place the filter on a clean towel and let it air dry completely. Avoid using a hair dryer or any other heat source to dry the filter, as this could damage the filter material.

Step 8: Reinstall the Filter

Once the filter is dry, carefully place it back into the filter housing. Make sure the filter is properly seated and aligned. Then, use the pliers to tighten the filter housing securely.

Step 9: Test the Pressure Washer

Reconnect the water source and turn on the power supply. Start the pressure washer and check for any leaks or abnormal noises. If everything seems normal, the filter cleaning process is complete.

Frequency of Filter Cleaning

The frequency of filter cleaning depends on several factors, such as the quality of the water supply, the intensity of use, and the type of pressure washer. As a general rule of thumb, it's recommended to clean the filter every 25-50 hours of use or at least once a month for regular users. However, if you notice a significant decrease in the pressure washer's performance or if the water flow is restricted, you may need to clean the filter more frequently.

Conclusion

Cleaning the filter of your wall mounted pressure washer is a simple yet essential maintenance task that can help to prolong the lifespan of your pressure washer and ensure its optimal performance. By following the steps outlined in this guide and cleaning the filter regularly, you can keep your pressure washer running smoothly and efficiently for years to come.
