Just a wee tip to anyone experiencing F33 fauly code with there boiler, take fan off and give it a clean, after 2 corgi plumbers, and the expense of a air pressure switch, discovered it was a dirty fan.

As i said 2 so called corgi registered engineers looked at the boiler and were as much use as a chocolate poker, had no option to have a look myself problem solved after 3 weeks, have since taken out insurance on boiler incase of any other issues. 
Corgi don't control the gas register try gas safe that's probably where u went wrong, dirty fan, very unusual

ollski better asked in cc IF of course you are elidgable, but fyi no it aint, pahh ok i am lying easier if it is of the wall.
Probably am eligible mate but also I'm anonymous and prefer to keep it that way
suspected it may be off the wall, thats why I probably copped for it. Is it pretty much like the old glowworm cxi type of thing with that storage tank wrapped in polystyrene strapped to the back?DIYnot Local
