Our CH boiler has stopped heating water for the household taps the CH is still working normally. The symptoms are as follows:-
- Turned of the ch and turned on hot tap it did not switch inself on but initially got a small amount of hot water. Did it again and this time just cold but again it did not switch itself on.
- Switched on ch and waited until boiler not running, turned on hot tap and it did fire up the light came on and I got a shot of hot water which then went cold?
- A small amount of water is dripping from under the boiler.
A friend reckons we need to replace the cold water flow switch. What do you think?
Cheers,
Bren
