Why doesn’t water come out of the Xiaomi Water Flosser 2 when using it for the first time?

Question

Accepted Answer

If the nozzle doesn't spray water during the initial use of the Xiaomi Water Flosser 2, it's likely due to excess air trapped inside the water tank, either from the manufacturing process or from the device sitting unused for an extended period. This trapped air can prevent the normal flow of water when the device is first activated.
To resolve this, follow these steps:
1. Fill the water tank with clean water, ensuring the tank is properly installed and securely attached to the main unit.
2. Turn on the device and run it for a few seconds. This will help push the air out of the system and allow the water to start flowing through the nozzle. You may need to run the device a few times until water begins to spray.
3. Alternatively, after filling the tank with water, lay the device flat or turn it upside down before turning it on. This position can help the air escape more effectively, allowing the water to flow properly.
4. If necessary, continue to let the device run until all the air has been expelled, ensuring that the water can flow freely through the nozzle.
Once the air has been cleared, the Xiaomi Water Flosser 2 should function as expected, providing a steady and continuous stream of water for effective oral hygiene. If the problem persists, you may need to check for any blockages or contact customer support for further assistance.
