Problem with Ferroli boiler?

My Ferroli boiler was working fine but then showed fault F35 which is problem with electrical mains. I reset the boiler and the heat and water both then showed 0, the presure showed 0.0 and a flashing '1' appeared next to where the pressure figure should be. I managed to get the boiler to come back on and got hot water but when I tried the heating it kept just flashing 1. Any ideas?
