my boiler is not working right but it only seems to be on the heating heati?

boiler make?
boiler model?
fault indicator lights flashing?
in what sequence?
does problem affect DHW or CH or BOTH?
my crystal ball is playing up so i cant tell what boiler you have
so i have to resort to using old fashioned methods of asking for as much relevant information as possible
otherwise youre gonna have to cough up for an engineer visit
