Manufactures do there own courses but they only cover there current range of boilers not older ones there are a few books around to help. The only thing is experiance and a lot of ringing technical lines and geting used to going through the process of how the boiler works to know were to look, and a multimeter will be your best friend
Im thinking about doing the mr.combi course but have heard mixed reviews anybody been on it, I havent done no fault finding at all, only installation so is it suitable for starters?

do the three day glowworm one, boys on my course had done the mr combi said glow worm was better
think the three days are multimeter ,combi and faultfinding
I have done the honeywell course which is helpful but not for boiler fault finding. It's more for fault finding the wiring of heating controls, two and three port valves, cylinder stats etc.
Unless they do a different one i don't know about.
