Mend Ariston Microgenus 28kw Boiler Fault Code Condensing

How can I solve fault code e33/34 on an ariston microgenus? ?

How do I solve the fault codes e33/34 on my ariston microgenus 28kw condensing boiler? I have changed the air pressure switch and cleaned all the silicone hoses from the switch to the fan. I've even removed the fan to check for blockages to the switch and had no joy!! Any suggestions please on what else it could be.

Did you ever manage to fix the problem. I have been told that this problem usually relates to a faulty flue
