Hi Guys the pilot on my gloworm cobi goes out when I try to use the hot water from the taps or when I turn the heating on - it will let me relight, but if I then try to use the hot water or heating again it just goes out - can anyone help.
Before this started happening there was a sort of loud humming noise coming from the boiler for about a day.
