Mend Glow-worm 24cx Flexicon Boiler Pressure Error

Yesterday it showed f9 today it's 2.4bar it still does not come on?

Glow worm 24cx Flexicon I've tried opening the two taps on the bottom of boiler but nothing at all happened even though the silver flexi pipe is connected permanently between the two water pipes. It makes a very quiet effort to start for about 3 seconds then goes quiet
