I have a Baxi Solo WM 60/4 RS boiler which has just developed a fault , last Thursday, where the pilot light does not stay lit. I can light the pilot and it comes on but goes out when I release the gas knob. It continued with this fault until Sunday of last week. This Monday morning I tried again and the pilot stayed lit and the boiler worked until today. Now I have the same fault where the pilot will light but not stay on. From reading the forums I see that the most likely fault is the thermocouple, however I would assume if this was the case, once it breaks that's it. As the fault sort of went and came back I suspect its probably not the thermocouple. I am beginning to suspect that it might need a service, as its not had one for a while and this fault could well be a build up of dirt in the burner area. One other thing to note is that the pilot flame is nice and blue ( not yellow ) so I assume that this area is clean ?
Any ideas or comments would be appreciated
