Looking after your machine
To always get the best performance from your Dyson purifying fan, it’s important to regularly clean it and check for blockages.
Cleaning your machine: 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. Do not use detergents or polishes to clean your machine.
Error codes: 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.
