Finally got to the bottom of my particular problem.....the gas valve needed replacing.
Although I would have felt comfortable physically changing it, I would suggest that you do what I did, that is get a qualified Engineer to change it. He had all the necessary meters to set it up and test...
Thanks Tony for your rapid response, I should really be able to take the issue forward now.
Anyone else with any advice on what I should do rather than what I should't do, again thanks in advance,
Regards
Dave
Please can you help.
I have a Worcester Bosch 350 Combi boiler that is probably 12 - 14 years old. This used to be serviced by WB on a regular basis before WB no longer wanted to know. The last time it was serviced by WB was probably 3 years ago, I have attempted to keep up the service myself...
