1. If the white light is flashing - the lid is in the shutdown state, please press and hold the button for 8S to turn it on, and then try again.
2. If the green indicator light is on - the lid has insufficient power, please charge it and then try again.
3. If the white indicator light is always on - It is in a vacuum-sealed state, and there is no excess air inside to be removed, so the air pump will not start.
4. In other cases, please contact us.
