Well...

If you don't get air, but water, then its not an air problem. It's a flow or balance problem.



Is this a new system converted from gravity?



If so, look for restriction plates in the radiator valves on the second floor.



If this is not a new system, probably a bad pump, or no power to the pump.

When

you re-filled the system, did you bleed from the 2nd floor first?
