procombi he boiler

[shepbarry]

hi

i have one of these boilers and it used to work fine but now there seems to be an airflow problem
the pilot light will not ignite unless the cover is unclipped and so that leads me to belive that the air flow is blocked but i have little boiler knowledge so i just need to know if there is a simple air tube that need to be cleaned out to solve this

the warning light stays green so i suspect that there is no real fault with the boiler itself.

i have since changed the air pressure switch but still the same problem ive now changed the two silicone pipes to switch and it started working for a day now its back to not starting again anybody got any ideas
thanks
