baxi back boler pilot light won't stay on?

hi it is likely to be the thermocouple failing to hold in, look at the flame [ie pilot light] when you light it and it should be directly on the tip of the thermocouple and the tip should be red hot,if this is ok then see if the tip has burnt away, this is the usual fault,check it out it will only take minutes to check it. bob
