Hi
About early November I had the 3 way valve and Thermocouple replaced on my Boiler - sorry to be a little vague but I believe its a honeywell. I normally have it set to heating & water but only control it by turning up and down my wall thermostat.
It had been totaly fine until I turned the wall thermostat up late last night. I could hear an awful clanking sound from the airing cupboard on the landing almost instantly. I went to look and expected to see a small creature hitting it with a large spanner!
I turned the boiler off from the mains and looked to seek advice today. Colleagues and forums all seemed to suggest that it would be trapped air. I bled my rads starting from the highest one and sure enough there was a 10 second hiss as air escaped. I also checked the other rads but found no air. However this hasn't stopped the noise coming from the boiler. If turned on the pilot light fires up and sounds like its starting nicely for about 5 seconds. Then the clanking starts and lasts for 20 seconds before it seems to totaly shut itself down. During this time I think I can hear a gurgling noise but cant be sure.
I have also checked the header tank and this is full.
Is there a possibility that there is air in the boiler itself and if so is there any way I can release this? Obviously any suggestions more than gratefully received! PLEASE HELP![code:1][/code:1]
