Enter the Bluetooth connection password for the app as 1234, then use the app to control the device. Why do we need to regularly clean the essential oil diffuser? Waterless essential oil diffusers work differently from water-based ones. When the essential oil evaporates inside the diffuser over time, it inevitably sticks to the interior walls. Over time, this can clog the diffuser, preventing the mist outlet from functioning properly. If there is no scent or spray after using it for a while, you can try cleaning the essential oil machine first. The interior wall of the machine may be blocked due to long-term dissolution. This does not mean that the function of the machine itself is damaged.

Because the air pump tube is prone to disconnect during transportation. Therefore, you need to disassemble the machine and reattach both ends of the air pump tube, and the machine will be able to produce mist normally.
