I have a Baxi heating/Water Boiler which is 6 years old. This last week it as started to make a loud continues clicking noise. It starts shortly after the boiler as ended, after about 5 minutes it starts to click intermittently then it becomes a constant clicking noise until I switch the tho power off to the boiler. Heating and hot water work fine when the boiler is on. thats all I can say for the moment.
