no water in rads

[bluekc]

just cured a leak on one rad - emptied system to do so . turned water back on to fill header tank cylinder and boiler .now have water in only a few rads , even if bleed screw removed completely on other rads - no water present.
boiler is floor mounted not combi .
cheers

You may need to open your 3 port valve to allow water into the rads.
Flick the switch over as it rests in hot water mode.

Check the ballvalve in the header tank is still working properly.
