A fault has developed with my Ferroli Maxima 35S boiler. The fault code indicates that the flue gas sensor may be damaged. This seems to have happened during the recent bad weather. Is it possible that rain water could have entered the boiler via the flue and damaged the sensor.
As the boiler will not fire up, is there anything I can do until I can get the fault fixed.
