I have rhe above boiler with the above fault code. Sometimes the heating works but others it cuts out. When you run the hot water the tempreture lcd sees the readings go mental thecuts out. The boiler would work for a while before cutting out which makes me think ita the pump lead rather than the pump or low water and there is 1bar in the system. Now the boiler won't start at all an records an F.0 fault. ( the NTC flow sensor was changed about a month ago).
Any ideas out there.
