firing up problems on my Ariston micro combi?
my Ariston micro combi boiler keeps firing up & then going out ,then firing up & going out,then firing up & going out,maybe 12 to 15 times then it stays alight for a while & then goes back to the on/off routine.This happens in heating & hot water mode.Any ideas.model number 23MFFI.
