Happy new year to everyone, please be gentle with me on my first post.
I have a icon 23t combi which is 7 years old, when you open a hot tap the boiler will only fire when the tap is fully open and so the water is at best aired. with the central htg on and the boiler fired the water at the taps is as normal (o.k) although the boiler still doesn,t go to high fire untill the hot taps are fully open. I' ve looked in the mi's and no referrence to a flow switch could be found.Am I on the right tracks with my thinking? Any advice would be much appreciated.
