Hello guys
This is an Ariston A23 Combi. The hot water works fine. When I put the central heating on it heats up the radiators. After about ten minutes running, the temperature reaches about 75 degrees. Then a humming noise starts coming from the combustion chamber. So I turn it off. Once it is fully cooled down if I turn it on again, the same thing happens. All the time, each day, the hot water is OK. What could be faulty in the combustion chamber ?.
I would like to have an idea before calling someone. It is not something I can do because it is a sealed area. Thanks for your help.
