Hello every one..

My boiler is an old Worm Hot Water Express 80, the hot water or central heating don't work. I don't have any of the original documentation so I would be greatfull if anyone who has some could either send me it or point me in the right direction...

At first the pilot light wouldn't light, so I assumed it may be the Thermocouple so I have changed this. I can not relaiably relight the pilot without it going out. The pilot light stays on for at least two hours so I suspect the thermocouple etc is now ok.

When I turn the tap hot water on the main burner turns on but within about 5 seconds the main burner goes out and also the pilot light. The thermocouple cooks and there is a click which I suspect is the pilot gas been cut off? I then have to wait 5 mins until I can relight the pilot.

Does anyone have any ideas as to what this could be.... Could it be a ventelation problem or something over heating? .... I've tried to clean the inside of the boiler with a vacume but that didn't help.



Anyone any ideas?



Thanks for your time

Daz.
