I have a Ferroli Optimax HE 31C combi boiler for a year now, I just noticed yesterday that when I turn the dial on the wall for the heating to come on, none of the radiators come on??!?
The hot water works perfectly fine, the little triangle shows up on the LCD screen next to the dial on the wall, but the little fire symbol on the boiler its-self does not come on to say it's fired up for the heating.

Can someone please help?

check that the boiler is not on summertime which is represented by a little sunshine picture on the boiler display failing that it could be the clock/programmer or room stat and finnaly the diverter valve but look for the sunshine first and if its on the display hold down the button with the sunshine on it on the user buttons for about 5 seconds and it will disappear from the display kicking the heating back in
