I changed a radiator valve and now the the Alpha 240e boiler will not light. I did not touch the gas supply and the radiator pressure gauge is correct. The neon indicators show everything should be ok and I can hear the boiler start but it does not ignite. I did need to use the reset button. Hope you can help. Thanks.

Its ok panic over as left the boiler on and it eventually lite. Although it went out several times after lighting the first time. I would be interested if anyone has any idea why this should happen but only out of interest. Thanks, its good to know this Q&A site exists. Steve.
