Heating comes on straight away some times.
Other times have to switch fuse on and off and it seems to work then.
Same with the timer works some time.
Is a combi boiler and hot water should run constantly but rarely works without the heating being turned on.
have had a new clcok fitted and valve for the water costing £100 but has not fixed the problem.
Has anybody else had this problem and can you offer any advise.
