Could anyone kindly answers my questions above as I'm going to give this a shot tonight and any guidance would be much appreciate. Last attempt before giving up .........

Yeah me too mate but I've spent so long on it now I'd really like to solve it myself 8) You know the 'just one more thing to try then I'll call in the professionals' :wink:

Thanks mgunn but I don't know anywhere near enough to be able to find this switch so might have to come back to that one later. Regarding the rads .... I have read a lot on the forums about pumps being the cause of cold rads. I did open the front panel on the boiler and turn the large...

Well things seemed to be going from bad to worse :( It seems to be branching out from a CH problem to a DHW problem :cry: My boiler fires up okay when the hot tap is turned on, but fails to stay hot for very long. After 20 secs or so the water turns luke warm then cold and then back to...

Read back through the faq and decided to check the pump. I can confirm it is set to 3 and when bleeding the pump water started immediately. I have tried everything, can anyone please offer me any further advice? I'm at a dead end now and desperate.

That was a dodgy rad mate. Now tested on all three dodgy rads and one good rad. Results are the same across the board, very good flow from the ls valves. Not what I expected at all, running out of troubleshooting options.

Actually, used my head a bit and checked the boiler pressure. Was down at flat 0 after running the ls valve. Let more water in and brought the pressure back to 1.5 then opened the same ls valve again and soaked ..... So looks to me like water flowing? Or am I wrong? Thanks again.

Right mate, done exactly what you said. When I released the ls valve at first the water came rushing out big time spraying all over the place, despite using a funnel into a pan. Anyways, it was strong for about 15 seconds but started to weaken until I got the valve fully open and...

I think this might be the issue then from everything I've described so far. Is there any product I can buy that will break down this potential limescale blockage?

Going to do it today mate. Can I check, should I have all working rads open and the heating turned on?

Also, forget to say that with only the problem radiators turned on the CH outlet pipe coming from my boilder does not get hot. Only when a working rad is turned on does it heat up. When I flushed the radiator in the livingroom there was a big build up of white type powder which I had to...

I have turned off all rads except one of the problem rads. Noticed now that my boiler is making some bizzare noises! Best way i can describe it is like when you boil a kettle with little or no water. Is this a good thing and potential air blocks are being cleared or is this a bad thing...

Still no luck but just to update my list of clues. I turned every single rad off last night both at the tvr (which does close fully) and the LS valve. I then turned the boiler on and went to the furthest away rad that is not working (in my livingroom) and opened the LS valve fully. Then...

No idea what pump I have mate but the boiler is a SIME Format 100C. Sorry for not mentioning this earlier, what difference might this make?
