Can anyone diagnose the problem with my Ferroli Optima 901?
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.
got similar prob with my brothers for the sake of testing i have shorted out stats 1 found to be faulty but replaced all 3 now looking at multi function gas valve will let ya know outcome
