Hi, I drained down the system and changed a radiator at the w/e. The system is now re-pressurised but when I try to run the boiler it shuts down after 5mins. The inlet pipe to the pump is very hot as is the pump but the outlet pipe to the diverter valve is cold. The pump seems to be running ok as you can hear it and it changes speed when the speed control swt is moved, but it seems its not pumping any water. Could it be air in the pump still or maybe the impellor has broken? Tried using the chrome screw in the centre of the pump to bleed it to no effect. Are there any ways of bleeding it?
The burner is working fine and there is no lockout.
Any help would be most appreciated
Thanks
