Okay my fault to start with as I started to bleed one radiator yesterday. It's a Valliant ecotech 838 boiler.
I think as a consequence it had dropped the pressure in boiler. This morning boiler was auto shut. Investigation shows code F22.
I tried the usual top up method but it failed. I couldn't hear any water moving at all when I open the valves. Added pictures to see if I'm missing something obvious.
