Shark Vacuum Hissing Noise and No Suction - SOLVED

Have you ever turned on your Shark vacuum only to hear a hissing sound? Don't worry, it's a common issue that many users face. But what does it mean when your vacuum starts hissing? Let's dive into the details.

What does the hissing sound indicate?

When your Shark vacuum is hissing, it's a clear sign that there is a blockage somewhere in the system. The hissing noise is caused by the air release valve, a feature on the vacuum to stop the motor overheating. 

Understanding the air release valve

The air release valve is a built-in part of the Shark vacuum that plays a crucial role in preventing the motor from overheating. When a blockage occurs, the air release valve opens to release the trapped air and prevent the motor from getting damaged due to overheating. This is why you hear the hissing sound when you turn on the vacuum.

How to resolve the issue

To get your Shark vacuum back to its normal working order, you need to locate and clear the blockage causing the hissing sound. Start by checking the hose, filters, and brush roll for any obstructions. Remove any debris or clogs that you find to allow proper airflow through the vacuum.

Once you have cleared the blockage, you can test your Shark vacuum again. You should notice that the hissing sound has disappeared, and the vacuum is running smoothly without any issues. Regular maintenance, such as cleaning the filters and emptying the dustbin, can help prevent blockages in the future.

Final thoughts

Dealing with a hissing Shark vacuum can be frustrating, but understanding the cause behind the noise can help you resolve the issue quickly. By clearing the blockage and ensuring proper airflow, you can keep your vacuum in top working condition and enjoy a clean home without any interruptions.
