HI the heating didnt come on tuesday evening so i checked the programmer and there was no display,so i changed the 3 amp fuse and i got the display back and both lights came on for the heating and water, but nothing happened until i turned the cylinder stat up and then the boiler sparked up but only for hot water not heating. so i bought another programmer and room stat but i still have the same fault, could it be the two port motorised valve for the heating as the one for the hot water does operate??
