Water not filling for heating system

[coolaboola12]

Hi All

I live in a 2 story house with the attic converted. Earlier today the heating upstairs was not working fully so i bled the rads and it seems good now upstairs

However in the attic conversion, the rads are stone cold. I believe there isnt enough water or pressure in the system to fill the rads in the conversion and when i open the release valve in the hot press then no water comes in so the pressure is staying really low.

Any idea why the water intake release valve isnt letting in water ?

Thanks for any help
