Hello,

I just bought P2 and getting started, but got stuck in water filling. The YouTube video shows, that after the first filling, the water should flow into the tube: Unboxing a Revolutionary Laser Machine: xTool P2 CO2 Laser Machine (youtube.com) 

The paper manual, which came along, tells nothing about water needs to be flowing into the tube - just wait 30seconds. I am experiencing the same issue, that after doing the first filling, no water is flowing into the tube. I proceeded as the paper manual says and did the second filling, but still no water seen in the tube. 

I would like to know if there is any issue or problem, before i proceed further.

Thank You
