quick run down is
glowworm back boiler about 10-15yr old
programmer lost power found to be fuse..replaced fuse getting hotwater again - however heating wouldnt come through, boiler firing on water cycle. the programmer sounded diffrent when i pressed +1 on heating compared to water so ive replaced the 922 programmer with a new fp975..ive checked al the wiring and setting switches twice. i am still getting it to fire and supply hot water but cannot get any heating..
any ideas please..
oh and i cant get to the pump as its under the floor but i think its working as i am getting the hotwater up to the tank.
thanks
