Hi all,
Im new to the forum so be gentle!
I have a Ferroli 77FF combi boiler and have a problem which Im hoping someone can give me an idea of what might be wrong?
The boiler normally works fine, however in the last few weeks, its started ocasionally running cold water when hot water is demanded, and then it will fire as normal, and then the burner cuts back off, and this continues. If I turn off the tap and then turn it back on, it can either be fine, or continue in the same cycle. During this cycle, when the burner switches off, the LEDs on the board show the green LED for "Air pressure switch on" and yellow LED for "Gas valve energised" both go out. As well as this issue with the DHW side, the boiler sometimes does a similar thing when CH is asking for heat, and when this happens, there is a surging noise, as if the fan is starting up, and then gets halted, then starts then gets halted, and this goes on and then eventually it will fire up.
All these are intermittent, and my Gas engineer, asked me to detail exactly what was happening with the LEDs when we had issues, and hes coming back in a few days to have a look. Just wanted any opinion as to what it could be in the meantime?
Any help much appreciated.
