Hi all, I've been out to repair a Ferroli Modena 102.
The hotwater is running hot, then the burner shuts off and the water turns cold. Then it sparks up again and turns warm again.
Also the heating cycles (it turns on, burns and then cuts out, then within seconds sparks up again and runs, so on).
This could be because the boiler is far too big for the little house its in. 6 rads in total.
I have fitted a part suggested to me by the fault flow chart, which I didnt agree with 100% so I called Ferroli and they agreed with the chart. (Water Pressure switch) - It didn't work, but then I forsaw this.
I need to get it done on my second visit as I'm so pushed for time, plus my other half now fully 9 months pregnant, so any day I'll have to drop everything and help her out!
Figured Gas Man would have experienced something along these lines. I have my suspicions that either a thermistor needs changing or the DHW sensor needs changing.
Oh and the client said that since I changed the Water Pressure switch, the ignition is much quieter....I said it shouldn't be. My thoughts are that when i drained the boiler to fit the part, I may have removed some S*** from it as the water was as black as coal.
Thanks in advance for any responses. Sorry to have banged on!
