... fire uo for few seconds and then a still red light was coming on. I wasn't much concerned as it usually happens when I don't use the boiler for several hours, but I have been trying since this morning but nothing. My boiler has 2 green lights, one of them lights up when I turn the heat on. I have been told to press the reset button twice, but when I did so the green light stopped lighting up when I was trying to turn on the heater. It only turns on if I keep the reset button pressed. What should I do? :(
