Work safely, disconnect the wires to the gas valve and check the valve coil for resistance. Your symptoms indicate a failed gas valve.
That goes without saying, but the guy was just asking for advice on what might be wrong with his boiler!!

Quite so but we are not meant to be encouraging DIY gas repairs!
If you consider my advice to be encouraging diy gas repairs, then you are just as guilty going on many of your past posts. People in glasshouses etc. if you had only waited you would have seen me giving correct advice regarding getting a repair done by a qualified person, but no, you couldn't wait for that. Such a shame. :rolleyes:
Tut tut Agile, you should have given Pete more than 8 minutes since his first reply for him to recommend hiring a RGI. Oh I do love it when the customer rings me up saying that his gas valve has failed.
