Hi To All

I have a heatline c24 boiler,The boiler was raiseing in pressure from 1.5 to 3.0 when heating on.I read on here about the expansion Vessel,On checking it had virtually no air in at all.So i released the pressure via the pressure release and used a pump to bring the pressure to 1 bar.(tested the valve and only air comes out no water) I have turn on the boiler only to get a flashing light on the +70 ( with an image of a arrow pointing up ) and the boiler doesnt start???I cant find my manual anywhere and cant find what this error is.I was going to bleed the rads,Does this sound right

Dont worry sorted....Found my manual the error was air pressure switch.
With me messing with the expansion Vessel valve i pulled two pipes off little connectors on the back of the boiler..Re-connected them and its working again :D
