Cleaning your machine
To always get the best performance from your Dyson purifying fan
heater, it’s important to regularly clean it and check for blockages.
If your machine shows an error code, try turning it off and then on again.
If this doesn’t clear the error code contact Dyson Customer Care.
For more information and support for your machine go to the Dyson Link
app or online: www.dyson.com/support
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.
