Hi,
Today I put my heating on for the first time in about a month but it lit and kept making a noise like it was going out and then right away igniting again but this was happening so fast it wasn't actually going out if you know what I mean, it was therefore making a noise like a dull puff every 2 seconds approx. I took the boiler front off and hoovered it all out and put it back together and it worked fine until I turned the switch off to the radiators but left the water heater on.
Any ideas what the problem is?
Thanks.
