Saunier Duval Xeon HE18 F1 fault code?
Saunier Duval Xeon HE18 boiler keeps showing red light and F1 in display, opened front and found earth lead to igniter green and corroded, repaired wire, worked ok for a day then earth wire appears same again? and fault returned can see igniter firing after only a couple of seconds max,but then shuts down,will also stop if you overide the program also?
