the flame comes on for about 20 seconds and then goes out but the pump is still running ,it stays lit if the hot water tap is turned on , but that is no good for warming the house. i have had this boiler for 7 years and every year something packs up , it has had 3 diverter valves and some electronic thing , sorry i cannot be more specific . the model is friendly format 80e

For my sime 60 problem I called in an engineer. The problem was that the system simply needed to be repressurised! I understand that systems like this lose pressure over time and repressurising is then needed. I am very thankful that the professional engineer that solved the problem also educated me about this matter for the future.

I also have a similar problem. My boiler is also about 7 years old, a sime super four. Pump is running but no flame. I have to switch it off, reset it, wait and the turn it on again. A pressure drop (cannot find the leak in the central heating system) and therefore suspect the boiler. Can anybody help or know of a boiler service company specialises in sime boilers.
