hi all
Just turned on the heating for first time in a few months, and I got the F25 fault code, which is "Water switch/System pressure too low".
Pressure was at zero, pretty much.
I found another thread on here and tried adjusting the two valves on the filling loop. When I switched the black plastic one, pressure immediately rose to about 3.0 (i.e. the red zone). The heating came on.
But now I think the pressure is too high? I think it's supposed to be about 1.3. Can I do anything to reduce the pressure?
And what position should the two valves be in for normal operation? At the moment the big black plastic one and the small metal one that needs a screwdriver to shift it.
I'm a bit worried about the pressure thing, so I've turned the boiler off for now.
