intermittent hot water?
I have a glow worm swift flow combi boiler about 10 years old, i have had different parts replaced over the years, the latest being a new fan fitted, but i am having an intermittent fault, which is that sometimes the hot water does not come on, on other times it comes on for a few minutes then runs cold, and then at other times it is fine, the ch works fine, any ideas ?
