Ninja 600f Don’t draw cooling water

Hi together , Bin absolute newcomer in the area motorcycle … So I got myself a Ninja ZX6r 600f bj 97 running with 35000km… I’ve already made some smaller rounds, in my eyes and from the feeling everything is good. Until yesterday, I drove about 100km , came home and when I put off I noticed that my bike loses cooling water , I walked away a bit back , everything was dry only on the parking lot was a small puddle on the rear wheel . Have bit dr under looked but did not see where it comes from. Well I first left it so, then I just went down and wanted to look right… So the tank of water is full, even over the line. Run to temperature went up, fan started turning, cooling water does not move? Does anyone know the problem? What should I check how?
