Ferroli combination boiler Must be reset button after its been off the grid? I have a ferrolli "Optima" combi boiler which has been cut from the mains. I can not restart, as I do not spark "in light of the night. I do not want to pay for an engineer if it's something as simple as that ressetting.
power grid is on, and I do not know why I'm having this problem
I hope this URL will be of some help. do not know your model number, but I would bet they all work the same way.
