A big hammer

undo the black nut on the front pull it out and turn it (ohh err misus) have a cloth handy as you will lose a drop or two of water

 

[alinavid]

I have already done that to undo the black plastic nut and water was poring out of that, for how long i need to keep lose that or I need to tight back ??thanks

 

[gas4you]

If you have tried to turn it after you pulled it out and it will not turn then new pump needed. Do screw up again or fit wellies!

 

[alinavid]

if i pull it out it makes noise like some thing moving fast, do i need to keep boiler off to do all that or it should be on constant heating.

Sounds like pump is ok then.

What boiler/system do you have? Does it have a 3 port valve or 2 2 port zone valves? Could be ch zone valve knackered or faulty 3 port valve head!

What do you mean by board? The boiler pcb? The heating programmer? I take it the heating programmer is on room stat is on high and calling for heat on the radiators as well as the hot water
