too much pressure in my glowworm 24ci?

I took out a radiator and that took all the pressure form my system. I refilled the boiler too high and now i have upto 4.4 bar in my system. I've tried bleeding several radiators for ages and the pressure fluctuates between 2.9 and 3.7. I fear leaving the boiler on and i cant wash.
please help

that sounds a bit silly being as the boiler has a pressure relief valve which lets go at 3.0 bar so i doubt you have put 4.4 bar pressure in it. double check the display to make sure its reading bar and not temp

thanks, but I've tried this a few times.
It sometimes goes down but then up again
can you advise how i make sure the filling loop is closed?

Your pressure is certainly too high - make sure the filling loop is closed, put a tray beneath a convenient radiator valve, turn the valve off, unscrew it from the radiator, catching any water, and take out as much water as you need. Go below 1 bar, then refill as required. Messy I know, but quicker than pulling water from the bleed valves - which will have the same effect.
