I`m looking for some guidance/advice woke up this morning to find no heating or hot water so decided to dig out the instruction booklet for the sabre he 35 boiler and under the trouble shooting section it says the green led should flash every 6 secs (which it does in the off position) however when i put the boiler on to auto or on positions the led flashes every 0.5 secs which according to the instructions there is a temporary fault and action required is to wait . tried turning off at mains etc to see if it will perhaps reset but no change. so i removed the outer white metal cover and checked some wiring connections to make sure they`re ok however as you look at the boiler above the control panel you have a silver panel with a circular sight glass in it should you see a flame when the boiler fires up ? because i cant. any help on this matter would be greatly appreciated cheers scott
