The bolier will not fire up, all the LED lights are illuminated, but nothing happens when i press the on switch. Also in the little viewing window there is no flame. I have also noticed that once a week the pressure drops to 1, and i have to increase it to 2.
Combi boilers have a safety cut out that operates when the pressure drops.If you keep losing pressure then you probably have a leak. Cure the leak and you will most likely cure your boiler problem.
