I have a Biasi riva compact M96.28SR/C. The boiler starts normally but then after about 10 minutes the burner goes out but with the fan still running and a fault code comes up on the 3 lamps ( steady red on the centre, flashing green on either side).......the boiler will not re ignite despite being called by the room thermostat and/or hot water. The fault code table says it is the Full Ignition Sequence ( not very helpful!). I have changed the temperature probe and the flame detection probe and thought I had the problem solved because the boiler ran for a couple of hours on a couple of days but it is back to only running for about 10/15 minutes before the fault code comes up. I have also tried disconnecting the wire from the condensor trap but the fault still comes up. I can only think now the Ignition Sequence PCB is faulty...I have inspected it visually and cannot see any obvious blackening. Before I spend over £100 on the chance that is the problem...any other ideas?
