Back filling the system to dislodge a blockage, is like moving a nail from one side of the drive to the other; you need to clean the system.

Was your plumber a RGI? If so he was not very good.
Look through FAQ, CH FAQ and wiki, various things about corroded systems and what to do about it.

To get water back in the pump, you must manually open the motorised valves, and bleed the rads.

If you have somebody that can help, take the screw out of the pump while you do it.
