we have fitted a heatline c24 compact combi boiler, it was fitted before we moved in, its about 2 years old, the previous owner didnt leave any manuals receipts or anything with the house, recently the ch has stopped working but hw works fine, i had a corgi plumber come & have a look, but hes never worked on a heatline, he cleaned it out all jets etc & it started working, well it worked following morning then nothing, the radiator symbol with the exclamation mark led stays lit, anyone in burnley lancashire who is familiar fancy coming to have a look
