2012 is turning into one disaster after another, but thought I would see if there is anyone out there that can help me. My Vokera Excell 80E goes to green then back to red light. It is not igniting, so no hot water or heating. This maybe a coincidence but we had no water from 3am until this afternoon, could it be something to do with that? My knowledge on dealing with combi boilers is small, but I can handle carrying out tasks, if there is someone who knows about old Vokera boilers and has some suggestions what I should try?
