My Ferroli Optimax 25c boilier is not producing hot water?
I have a Ferroli Optimax 25c boiler which stopped producing hot water. The presuuer is correct, the display is flashing. When the hot tap is turned on I cannoit hear the boiler igniting.
Swap the flow meter for a new one. It is positioned on the cold intake pipe where it enters the boiler. There are three wires on the plug that connects to it coloured red,blue and black.
