British gas service engineer replaced main circuit board to solve initial problem but same thing reoccured with new PCB in situ ? Problem being that pilot goes out and neither radiators or hot water are available. Flame warning light does not switch on but fan can be heard after following usual "fire-up' procedure. Symptoms leading up to this were radiators working but intermitent loss of hot water ? Any clues, or sound familiar ? Thanks in advance.
