we have a baisi boiler and we have just fitted a new radiator downstairs. we bled the full system and the heating and hot water was working correctly yesterday. today there is no hot water or heating and a red light on the boiler. any ideas? possibly an airlock in the boiler?

thanks. already done that and the pressure has remained the same throughout at 1.5 . its trying but its just not firing up

Im not a plumber,,,,however i will suggest a solution,

You need to add water to the system as the pressure is down. Use the filling loop under the boiler to fill it. It should be filled until your boiler guage reads a 1 bar.
The filling loop will need to be connected to both screwed connections and the valve opened until the right pressure is reached ( 1 Bar)

Hope it helps
