Pump not working

[Bullbags]

Fixed a leak in the c/h system pipework, (drained system down) re-filled the system (combi) and all the rads working fine. Large house with underfloor heating in main lounge. The pump running this will not start up again even though the rest of the system is fine. I have bled the pump but still no joy.
Any ideas please on how to get this pump working so that the underfloor heating works?
Many thanks

I take it you are saying the underfloor heating pump is the one that is not working?

I take it there is a call for heat on the underfloor circuit and there is 240VAC present at the pump?

Try un-doing the bleed screw and inserting a flat bladed screwdriver to turn/free the pump.

Yes its the underfloor heating pump that's not working.
Will try what you suggest.
Thanks Dave
