baxi barcelona not firing up

[jhart]

Hi,

I'm new to the forum so I'm sorry in advance for any mistakes/rules I break, please let me know and I'll sort it out.

My baxi barcelona boiler (2002) is not firing up; it started getting less reliable and now I can't coax any life into it at all. I don't really know what I'm dealing with, I know it could be a problem with the sensors on the flow/return pipes, but just wondering if anybody had any advice/help for me, or had encountered a similar issue?

Thanks so much in advance.

The only mistake you have made is lack of information, does your boiler run when you run the central heating ? what type of valves do you have ? any lights on/flashing or strange noises, sealed system or open vent ect ect
