I have a Biasi M110.32SM/E . Problem is cant ignite boiler in domestic or ch mode. Fan runs but nothing ignites. Removed sparking probe. It sparks for about 5 seconds when a tap is run. Switch tap off then back on and it will sprk again and so on. Gas valve seams to be operating. Stumped any advice would be gratfully received. MANY THANKS. MARTIN

If the boiler gets to ignition stage. And you have gas to boiler but no flame then the gas valve is no good. Call an engineer.

If the boiler sparks then the fan switch is ok, maybe a silly question but do other gas appliances work ok, do you have a card meter and does it say on when you push button A?
is the boiler gas iso valve open?
