Silvio, mine did this as well. The issue appears to be inability to draw back the fluid on cooling and/or drawing in air/vapor instead.
Hoses, caps, etc...
I did find that having a cap that has one of the pressure relief valves/levers allowed me to purge the vapor and get a vacuum to draw back fluid.
