Hello experts.
I would appreciate a little advice please.
I have read the other posts about this problem on this forum. Mine is also intermittent, could possibly be associated with windy days. Flame failure on fire-up using hot water and hot water + central heating settings. Also (not often) when the thing finally ignites, flame sometimes goes out & re-ignites. Inner chamber access panel seal appears OK. Fan comes on with good draught. Flue unobstructed. Idle water pressure increased from 1.5 to 2 BAR to no effect. Reset switch used no effect. Beginning to suspect Air pressure switch. Is there an easy way to prove diagnosis? anything more complicated I will leave for a professional, but as intermittent problem need to try to localise down a bit.
Many thanks
