when you run the hw tap does the led under the tap light up? (on the boiler facia)this shows that your flow switch has been activated. i would check/replace the venturi as these are plastic and very brittle but you will need to get the gas installer back to check it out for you
i used to hate working on worcester cdi,s but theyre easy to fault find on
i dont think i have ever changed a div valve without cutting my hands to bits .i can fit them in under an hour now but my first one took me about half a shift and i was tearing my hair out.the fascia panel always breaks...
are there any motorised valves at the cylinder. i would guess this to be the problem .if it is a system boiler
if its a combi it could be anything from a diverter valve,flow switch depending on the boiler make
there isnt enough info to help you though sorry mate!
hi there
i replaced the gas valve as it was faulty but when i was setting the pressures the max press was 14mb and i couldnt adjust it even though i used the correct method .i adjusted the min press as normal but the max press just wouldnt adjust any thoughts
ps i am gas safe registered
i would drain the radiators on the level of the house you will be working on .open the drain valve if accessible and open the rad bleed points of the rads you will be working on .
you will need to alter the pipework to suit .you may be better moving the t pieces so that your pipes come...
