In this article, I will discuss some of the most common reasons why your Dyson Air Purifier keeps turning off, and I will also provide some solutions to help you resolve the issue quickly. 

Dyson Air Purifier Keeps Turning Off?

Key Takeaways:

Dyson air purifiers may turn off unexpectedly due to overheating, motor malfunction, power issues, software issues, sensor issues, or clogged filters.

Troubleshooting solutions include:

  • Ensuring proper airflow.
  • Checking power connections and cords.
  • Resetting or updating software.
  • Cleaning sensors.
  • Tightening loose screws.

If problems persist, contacting Dyson customer service may be necessary.

Reason On Why Your Dyson Air Purifier Keeps Turning Off


Overheating is a primary reason why air purifiers shut down. It all boils down to proper airflow. 

Air purifiers have a fan that spins to pull in air, but when there’s not enough airflow due to a huge room or some internal hiccup, the fan’s gotta work extra hard. 

This causes it to overheat, putting stress on the whole system and causing the air purifier to shut off.

Motor Malfunction 

If your air purifier shuts off, a motor malfunction could be the culprit. The motor is responsible for powering the fan, which circulates air through the unit. 

The fan can’t function properly when the motor is acting up, causing the air purifier to turn off.

Power Issues

Your Dyson air purifier might be shutting down because of power issues. If that’s what’s going on, here’s what you can do to fix it:

Give the power source a once-over: Make sure your air purifier is plugged into an outlet that’s working. To be extra sure, plug in another gadget and see if it works fine. If not, switch to another outlet or give your electrician a ring to sort it out.

Eye the power cord: Look closely at the cord for any signs of damage or wear, which could make your air purifier call it quits unexpectedly.

Keep your cool: If you think the power source or some wonky internal parts are making your air purifier overheat, unplug it, let it chill for a bit, and then give it another go.

Software Issues

Although software issues aren’t commonly cited as a reason for air purifiers shutting down, they could play a role. 

However, some air purifiers have companion apps for remote control. If the app malfunctions due to incorrect login credentials or outdated software, it might impact the air purifier’s operation. 

So, while software issues aren’t a prevalent cause for shutdowns, they shouldn’t be completely ruled out when troubleshooting air purifier problems.

Sensor Issues

Dyson Air Purifiers have sensors that detect the air quality in the room and adjust the device’s settings accordingly. 

If these sensors are malfunctioning, the device may turn off unexpectedly. To resolve this issue, try cleaning the sensors with a soft, dry cloth, and ensure any objects do not obstruct them.

Filter Replacement Reminder & Clogged Filters

A clogged air filter can indeed cause an air purifier to shut down. Filter replacement reminders help ensure that filters are changed regularly to avoid such issues. 

Many modern air purifiers have filter change indicators, and some devices like Google Nest even offer a reminder feature.

To troubleshoot and avoid shutdowns due to clogged filters, follow these tips:

Check and clean or replace filters according to the manufacturer’s recommendations. Remember that some filters are designed for cleaning, while others should be replaced.

If your air purifier has a filter replacement reminder, ensure it’s enabled to help you stay on top of filter maintenance.

Refrain from using disposable filters, as this can put a strain on the air purifier’s motor.

Lose Screws

Loose screws in an air purifier might not directly cause it to shut down, but they can contribute to other issues that may lead to a shutdown. 

Loose screws can cause internal components to become misaligned or create excessive vibrations, impacting the air purifier’s performance or damaging sensitive parts over time.

To prevent problems related to loose screws, follow these tips:

Periodically inspect your air purifier for any visible loose screws and tighten them if necessary. Ensure not to overtighten, as this could damage the device or strip the threads.

If you hear unusual noises or vibrations from the air purifier, check for loose screws and tighten them. 

These sounds may indicate that something is misaligned or malfunctioning due to loose connections.

If you’re uncomfortable with checking and tightening screws, consider consulting the user manual or contacting the manufacturer for guidance.
