I have a Ferroli Optima 901. When the hot water is run for a period of 3-4 minutes the boiler cuts out and the pilot light goes out. The central heating works fine.

I have had engineers look at it and within the last 15 months I have had the PCB board, the overheat stat and the HW stat replaced.

Please can somebody help I am getting pretty fed up with the thing.
