no water pressure in a Vokera linea 28

[Dave1966]

I lost my water pressure when i removed a radiator and i can't get the pressure back up. I have pressurised the expansion vessel and when i do this the air just hisses out of the auto air bleed valve, is the expansion vessel knackered or is it the auto air bleed valve on the pump or both

Try asking in "plumbing & central heating".
(I think if you report your own post someone will move it for you.)

more info please. did you drain the whole system ? rad removed permanently ? why did you need to do anything to exp vessel ?

If air keeps coming out of the air vent and the expansion vessel will not hold any pressure the vessel is bust. The filling loop not working on these is a common problem. Are you saying you can't increase the pressure in the boiler by opening the filling tap?
If so , the non return valve in the filling loop is probably stuck shut.

I don't know why you are involving the expansion vessel !

Your boiler is repressurised using the black lever on the right underneath.

But there is a common fault caused by a blockage within the filling path. That can be quite tricky to clear.

later Lineas have two valves , the three way valve that you turn to the 6 Oclock position to fill the boiler and another vave at the other end of the filling hose you need to open both if you have this style
