Hi guys
new to this. Got a e33 code and then sometimes e34. Then boiler fires and runs fine, then decides when I put a demand on to play up. Doesn't really know what it wants! I've tested air pressure switch, checked all hoses, checked flue clear, had fan out and checked air way is clear. All seems to be ok. I'm a gas safe engineer before anyone asks. Number 548337. Any help gratefully accepted
