Cleaning the machine
The following areas should be checked and cleaned to maintain the machine's performance:
Clean the loop amplifier with a dry or damp cloth.

Clean the Main body with a dry cloth.
Clean the shroud with a dry cloth or soft brush.

Please select the appropriate option
If you have experienced issues connecting to the Dyson Link app between the 1st of January to the 8th of January. Please unplug the machine from the power supply for 10 seconds. Then leave the machine plugged in for 5 minutes before reattempting to connect.
Please select the appropriate option
Please select the appropriate option
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.
We're glad the problem's been solved.
Please let us know if there's anything else we can help you with.

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.

Ensure the power cord is plugged into the center of the base.
Plug the machine back in and retest.

Unplug the appliance from the mains electricity supply. Slide the buttons down on either side of the shrouds.

The shrouds will release with the glass HEPA filters attached.

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.
The display will not stay on my selected screen
The interface is designed to stay on the screen you select. Please ensure the remote is not being accidentally pressed.
My display is reading green but the fan is working at high speed
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.
My readings are showing in different colours
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 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.
How long has your purifier been turned on for?
If your machine is new out the box and has not been turned on for over an hour, please allow a full hour to complete, with your purifier plugged into a secure power source.
Once the full hour has elapsed, turn the machine off and then on again, either with the main power button on the machine, or the remote control.
If your purifier has been plugged into a stable power source for over one hour, and the VOC and/or NO2 screens still do not show, please unplug your machine from the wall, leave for one minute, plug back in, and then turn on using either the main power button, or the button on the remote.
