Thanks - really useful to know, especially after having had an F2 flame out error code. Do you know where the contaminant the causes the blockage comes from? Could it have got in via the flue?

Yeah, through the flue most of the time. Could be from sucking in dusty air if there's construction going on for example, and sometimes bees go in there. It can also get filled with dirty heating system water from a hole in the bottom of the heat exchanger.
