firstly, apologies for seeking help rather than contributing something!
but as you know, without central heating survival is very difficult especially with old aged parents
GCH system, starts up as expected with green LED (light) & a humming sound, i can hear a tick sound when we turn the hot water taps.
While switching on Heating, the small LCD status panel shows temp, increases upto 18 degree, it waits for a while and shows F2 on LCD and LED turns to red.
BTW, model is 24ci
any help much appreciated
Thanks
