How can I fireup my Ferroli 102 (0208L83093)?

Hi all desperately need your help!
My Ferroli boiler system was working absolutely fine, in th morning couldnt get any hot water so when checked it was not lit.. as I didnt have any paper work and know what to do so came online and try finding any solution, some one mentioned in one of the websites to start from the begining, so switched it off, give few minutes, moved the thermostat(Honeywell) to zero, then turn the main electric power on, moved honeywell to 25'c, and turn the on/off nob on the boiler to on, heard click and Wolaaa! it worked and the boiler started I can see the fire from outside. left it and started doing other things, later found out the heating is not as it should be, so when check it was off again, tried all the things again but all in vain, as i can hear the pump/motor pumping the water in the cerntral heating system but there is no fire, and both the LED's for fire are not lit as well.....
Dont know what to do, Got small children at home and weather is cold, please someone withkind heart help as soon as possible./.....
looking forward for any solution... as it is weekend and night so cant afford to call a gas safe engineer till the week days....
