Thanks for the feedback ACP.
As a engineer came and start changing every time a part guessing witch one it was i think i planed to have a qoute for a new one becouse already old one i think.
But recently i take of obe of the led of the pressure switch and the code didn't appear any more when putting it back the code f1 came back;s i presume that one is the problem.

All the relevant answers you are likely to find were in those links. To summarise:

F1= no flame detected

Likely causes:

* No gas or faulty gas valve
* Check flame electrode and cable for defects
* Check ign unit on gas valve
* Check fan operation
* If boiler has overheated reset the overheat sensors located on the left hand side pipework - little red switches on a sensor attached to the pipe.
* CVI unit could be faulty
* Possibly air pressure switch

I believe jaguar boilers were made by Glowworm. I also believe that Glowworm offer fixed price fixit. I have used them myself on two occasions. the advantage of getting the maker to do the job is the engineer will have specific product knowledge and will have a van full of product speciific spares - they are also reasonable price.

Oh, they are also Gas Safe certified so can work legally on gas installations, whereas those who are not certified cannot legally do so.
