Why Does My Dyson Vacuum Keep Shutting Off?

Do you find yourself frustrated with your Dyson vacuum constantly shutting off? It can be a major inconvenience when you’re in the middle of cleaning your home, only to have the vacuum stop working unexpectedly.

Luckily, there are a few reasons why this might be happening, and some simple solutions to get your vacuum back up and running. One common reason why your Dyson vacuum may keep shutting off is due to the thermal sensor.

This sensor is designed to protect the vacuum from overheating, which can cause damage to the motor. If the vacuum gets too hot, the thermal sensor will shut it off as a safety precaution. However, there are other factors that can trigger the thermal sensor, such as a clogged filter or blockages in the vacuum’s airflow.

By understanding how the thermal sensor works and checking for blockages, you can easily troubleshoot this issue and get your Dyson vacuum back in working condition.

Understanding the Thermal Sensor

So, you’re probably wondering why your trusty vacuum keeps turning itself off, and the answer might lie in something called the thermal sensor.

This small device is responsible for ensuring that your Dyson vacuum doesn’t overheat and cause any damage. The thermal sensor function works by monitoring the temperature of the motor and shutting down the machine if it gets too hot.

The thermal sensor is an important part of your vacuum’s overheating prevention system. It helps to keep your machine from getting damaged by shutting it off before the motor gets too hot.

This is especially important if you’re using your vacuum on a regular basis or for extended periods of time.

If you’re experiencing frequent shutdowns, it might be worth checking the filter and cleaning the dustbin to ensure that your vacuum’s overheating prevention system is working at its best.

Checking for Blockages

You’ll need to inspect the vacuum for any blockages that may be causing it to turn off abruptly. A clogged vacuum cleaner can cause overheating, which in turn triggers the thermal sensor to shut off the machine.

Check The Hose, Wand, And Filter For Debris Or Obstruction

Check the hose, wand, and filter for any debris or obstruction. Use cleaning techniques such as removing the filter and washing it with water or using a soft brush to clear out the hose and wand.

If you’ve tried these steps and the issue persists, it may be time for professional maintenance.

Check The Brush Head For Blockages

Sometimes, blockages can be harder to spot, especially in the motorized brush head. Turn off the vacuum and unplug it before examining the brush head for any hair, string, or other debris wrapped around the brush roller.

Use scissors or a seam ripper to gently cut through any tangled material, making sure not to damage the brush bristles.

Clean the brush head with a damp cloth and let it dry completely before reattaching it to the vacuum.

These simple steps can help ensure that your vacuum is free of blockages and running smoothly.

Maintaining Your Dyson Vacuum

To keep your Dyson running like new, it’s important to properly maintain it and perform routine cleaning tasks.

Cleaning techniques vary based on the model of your Dyson vacuum, but in general, it’s important to clean the filter regularly, empty the bin after each use, and check for blockages.

  • You can clean the filter by removing it from the vacuum and washing it with cold water. It’s important to let the filter dry completely before placing it back in the vacuum.
  • Emptying the bin after each use is also important, as a full bin can cause your vacuum to lose suction power.
  • Checking for blockages is essential to maintaining your Dyson vacuum. Make sure to regularly check the hose and brush bar for any debris.

In addition to routine cleaning tasks, it’s important to replace parts of your Dyson vacuum when necessary. Replacement parts, such as filters and brush bars, can be found on the Dyson website or at a local retailer.

It’s important to follow the manufacturer’s instructions when replacing these parts to ensure proper installation.

By regularly maintaining and replacing parts of your Dyson vacuum, you can ensure that it will continue to function properly and provide you with the best cleaning results.

Remember, a well-maintained Dyson vacuum is a long-lasting one!

Troubleshooting Other Issues

If your Dyson vacuum seems to have lost suction power or is making strange noises, don’t panic, there are a few troubleshooting techniques you can try to fix the issue.

  • First, check the filter and empty the bin to ensure there’s no blockage or debris.
  • If this doesn’t solve the problem, try replacing parts such as the brush roll or hose. These parts can wear out over time and contribute to a loss of suction power.
  • If you’re unsure about how to replace these parts, check your user manual or contact customer support for assistance.
  • If your Dyson vacuum still isn’t working properly, there could be other issues at play. Check the power cord and plug to make sure they’re securely connected and not damaged
  • If the vacuum is overheating, let it cool down for at least an hour before trying to use it again.
  • Additionally, make sure the brush roll is clean and free of tangled hair or debris, which can cause the vacuum to shut off.

If you’ve tried all of these troubleshooting techniques and your Dyson vacuum still isn’t working, it may be time to contact customer support for further assistance.


So, if you’ve been struggling with your Dyson vacuum constantly shutting off, don’t give up hope just yet! By understanding the thermal sensor and checking for blockages, you can easily troubleshoot and solve the issue.

Additionally, regular maintenance can keep your vacuum running smoothly and prevent future problems.
