During the carbonating process, water spray or water leakage occurs. What should I do?

There may be a few possible situations:
1. The water bottle is not tightened. Please check if the water bottle is tightened.
2. The amount of water in the water bottle exceeds the maximum water line. Especially in summer, if the water volume exceeds the water line, it is easy to cause water spray or leakage at the bottleneck.
