    Hi all,

    I'm currently working on a Biasi Riva Compact M96.28SM/C. The boiler doesn't seem to fire up however.

    The fault lamps (Left flashing green, Center Red, Right Flashing green) point to a Lack of burner ignition (no ignition signal from
    the full sequence ignition device).

    It started off as an intermittent fault where the boiler would cut off every few seconds and restart itself and occasionally displaying the fault lamp as above.

    But now. the boiler does not appear to fire at all. The same fault code comes up when the heating and/or hot water is called for.The fan and pump are running.

    I have replaced the ignition pcb and the fan.

    I have also tested the CH and DHW temperature sensors aswell. (Resistance of over 10k ohms)

    Would appreciate if someone could point me in the right direction of anything else i could change/test.

    Thanks in advance.

    and your gas safe registered? sounds like a simple fault, why did you change the fan?

    Hi,

    Yes i am gas safe registered. Waiting for approval for entry into the combustion chamber.

    The fan was an unrelated issue which i had repaired over there previously. I just thought that i would add that the fan was relatively new so it was unlikely to be an issue in this particular case.

    soon as you get your approval, post your question in the combustion chamber and one of us will point you in the right direction :D
