If your smart diffuser is not spraying, your first step is to check your fragrance levels. Do this by simply opening the fragrance access panel on the smart diffuser and carefully open the fragrance bottle to check the level. If there is still fragrance remaining in the bottle, it may be that you aren’t noticing the fragrance because your smart diffuser settings need to be adjusted. Try a higher level. If you’ve confirmed there is fragrance in the bottle, press the “QUICK REFRESH” button. You should see and hear the fragrance spray. If you do not, please contact support through text (949) 229-2191 or email support at support@calif.ebizonstaging.com
