Hi all i have a biasi m96.24sm/c RIVA COMPACT HE combi boiler i believe it was fitted in 2007/8 new system then with all new rads.
The boiler fires up for dhw and c/h but in both cases only lasts for 10 seconds and then the flame goes out. Not always, but mostly the red light in the middle comes on with both green lights flashing. I reset and it will do the same thing every time. Always stays on for seven to ten seconds and goes out. The pressure is 1 bar. The tenent decided to up the presure to two bars before calling me out so i have drained back to 1 bar. It did work for a day but now is exactly the same.
There is a sensor (presume temp sensor) to the left of the boiler with a blue conector on it and i was wandering if this could be the culprit if it is telling the boiler that the water is already hot enough!
I have looked at previous posts and the only one i could see where it might be similar, the condensing pipe was mentioned being frozen. The pipe is not frozen as the temp outside is 10 degrees but i am now wandering if there is sediment in the u part. Could this be the problem or am i miles off. I have had boilers before where there has been filters to take out and clean, does this boiler have one.
Any advise greatly received
I hope someone can help.
