Cleaning the machine

To always get the best performance from your Dyson purifying fan, it’s important to regularly clean it and check for blockages.

If your machine is dusty, wipe with a damp lint-free cloth.

Look for blockages in the air inlet holes on the filter and the small aperture inside the loop amplifier.

Use a soft brush to remove dust and debris.

Don’t use detergents or polishes to clean your machine.

Run the purifier for 1 minute at the highest temperature setting.

NB: The heating elements will only work with the airflow facing forwards.

Target temperature

The heater will not operate unless the target temperature is above the room temperature. The temperature set on the machine is the target temperature of the room, not the temperature of the fan; the temperature from the fan when in heating mode will not change.

Press the red temperature control button until the digital display on the Main body shows 37°C.

Intermittent power

Dyson fan heaters and hot and cool purifiers have a positive safety feature where the machine deliberately switches off after 9 hours of continuous heating. This would also occur if the machine is set to auto and providing heat constantly for 9 hours. NB: This feature cannot be switched off.

Remote control check

Are you using a remote control for other appliances (such as a TV) near the machine?

Is the machine under direct sunlight or flourescent light?

The sensor on the machine that receives the infrared signal from the remote control may malfunction when exposed to direct sunlight or fluorescent light.

Please move the machine so that is not under direct sunlight or fluorescent light.

Unplug the machine

The operation of the remote control for other appliances is likely interfering with your Dyson machine.

To prevent further interference, unplug your Dyson machine when not in use.

Check and clean machine

To always get the best performance from your Dyson purifying fan, it’s important to regularly clean it and check for blockages.

If your machine is dusty, wipe with a damp lint-free cloth.

Look for blockages in the air inlet holes on the filter and the small aperture inside the loop amplifier.

Use a soft brush to remove dust and debris.

Don’t use detergents or polishes to clean your machine.

Your filter may need replacing.

Check filter life within the app, on the display screen, or for excessive build up of dust within the inlet.

Please follow the steps in the video.

Find the text version of the step-by-step guide instead, under "Has this resolved the problem?"

Changing your HEPA+Carbon filters

Before changing your filter, switch off and unplug your Dyson purifying fan heater.

The remaining filter life is displayed on the screen and will indicate when your non-washable filters need replacing. Press the Information button on your remote or check on the Dyson Link app.

You'll need to reset the filter life on your machine.

Your machine comes with a permanent catalytic filter and a HEPA+Carbon filter.

You won't need to change your catalytic filter.

To change your HEPA+Carbon filter, push down on the buttons either side of your machine to release the outer cover. Push down on the tabs to remove the filter.

Push the replacement filter into the outer cover and make sure the tabs click into place.

Put the outer covers into position on your machine and push firmly until they both click securely into position.

Plug in and switch your machine, and reset your filter life.

Resetting your HEPA+Carbon filter life

It's important to reset your filter life after you have replaced your filter.

Press and hold the Night mode button on your remote control.

The display on your machine will countdown from five, the filter life will be reset and your machine is ready to use.

When your purifier switches from front to rear airflow there may be a clicking sound as the motor adjusts direction.

This is a normal sound for the purifier to make and is not an indicator of anything wrong with your machine.

Check base

Check around the base of the machine for any debris or obstructions.

Please try taking the filters off, then reattaching them to ensure they are correctly clicked into place. When attaching the filters, press in and up, and check there are no gaps or loose areas.

If the filters are not attached correctly, a triangle warning may show on your screen. If this happens, please reattach the filters securely.

Continuous monitoring

The continuous monitoring option is used for air quality, temperature and humidity data to be relayed to the machine and app at all times, even when you have turned the purifier off. The sensors have small fans that maintain airflow for continuous monitoring, but this should not cause any audible noise interference.

There may be instances when the display shows green, indicating high air quality, but the fan speed is still high. This is due to the machine constantly seeking to maintain a good air quality, and in scenarios such as rooms with leaky windows, the machine must work harder to maintain a good air quality.

This will only happen when the machine is set on auto. To turn off Auto mode, please select Manual mode, either using the remote control or on the app.

Please check the following on the app:

Swipe up to reveal the setting tab and tap to open options.

Swipe down to find the continuous monitoring option and tap to open.

Turn OFF the 'Collect data when in standby' option. (The icon will turn grey when turned off). Save the change by pressing 'Done' at the top right of the page.

Continuous monitoring can now also be turned on/off by pressing the 'Auto' button on the remote control for five seconds.

Retest the machine.

Restart the machine

Unplug the machine and leave it for 10 seconds.

Plug the machine back in and retest.

Don’t use detergents or polishes to clean your machine.

Remove the filters

Switch off and unplug the machine.

To remove your HEPA+Carbon filter, push down on the buttons either side of your machine to release the outer cover. Push down on the tabs to remove the filter.

With the HEPA+Carbon filter removed, put the outer covers into position on your machine and push firmly until they both click securely into position.

Plug in and switch your machine.

Please ensure you have the most up to date software downloaded before beginning any checks. We strongly recommended enabling auto-updates in your Dyson Link app settings, to allow the most up to date software to be installed as soon as it is available.

The colour of the numbers and readings on the display are linked to the air quality of the respective category.

Green denotes a high air quality, with low pollutants, and red, low air quality with a high amount of pollutants.

Different categories can have different levels of pollutants at the same time, and will therefore display in different colours.

The interface is designed to stay on the screen you select. Please ensure the remote is not being accidentally pressed.

There may be times when the display is showing green but the fan speed is still high.

This is due to the machine always trying to maintain high air quality. For example, in a room with leaky windows, the machine has to work harder via a higher Fan speed to maintain a high air quality.

If you want the fan to be quieter, you can choose to change the airflow direction to face backwards, or turn the machine to manual mode and lower the airspeed.

Fault

Reset the machine.

Unplug the machine and leave it for 10 seconds.

Plug the machine back in and retest.

Night mode is not working

When in Night mode, your machine will automatically sense the ambient light level and adjust the resting screen brightness accordingly.

If the room is bright, (for example, the lights are on), the screen's display will be set to minimum brightness. If the room is dark (lights off) the screen is turned off.

In both scenarios, when the machine is interacted with, the screen brightness will uplift.

If your screen is not displaying correctly (incorrect reading, white screen etc), please ensure you have updated all the software to the latest version.

When setting up a product, we strongly recommend enabling auto-updates, to allow your machine to easily download the latest software.

To enable auto-updates, open the Dyson Link app and click the cog at the top right of the home screen.

Click 'Your Purifier's settings'.

Scroll down to 'Software' and enable Auto-update.

Restart the machine

Switch off and unplug the machine.

Ensure all outside doors and windows are closed.

Vacuum the four sensor slots to the left of the LCD screen.

Plug in and test the machine.

Switch off and unplug the machine.

Move the machine to another room.

Plug in and test the machine.

The first time your purifier is turned on, the gas sensors will perform a self-calibration which takes one hour after which time they will work normally.

If the power cuts out within the hour, the initialisation period will continue from where it left off.

If your machine is new out of the box and has been turned on for less than one hour, the machine may still be calibrating. This process takes up to one hour to complete. Please leave the machine running during this time.

After one hour, turn the machine off and then on again. Press the power button on either the main body or the remote control.

If your purifier has been plugged into a stable power source for over one hour and the selected readings still do not show, we advise that you perform a factory reset.

Press and hold the power button on both the main body and the remote control.

Continue to hold the buttons until the LCD screen shows a countdown timer.

Once the countdown has been completed, the machine will have reset.

Your purifier will turn on automatically. Leave your machine running for one hour to perform self-calibration.

Note: By resetting the machine, your Wi-Fi network details will have been removed and your purifier will no longer be connected to the Dyson Link app. You will need to restart the connection journey.
