Central Heating

Need help with boiler, any ideas...

Hi, I have an issue with my Combi Boiler (Ravenheat CSI85 AAA(T). I know it isn't the best boiler but it serves a purpose and the time I've had its been great. It works fantastic from a Hot Water point of view, you run the tap and the boiler kicks in the water heats up. But the Central Heating on the other hand is a doesn't story, for some reason it has stopped working. It hasn't been on for a few months as we haven't needed it on however this appears to be the worst decision I've made recently as the Central Heating now appears to be broken.

The is working Fan, as is a the pump. My Thermostat is a nest and that is also working correctly however when you switch on the Central Heating still won't kick in, I've tried to use the Boiler directly and the same result. It is almost as if the 'manual' button to turn the Central Heating on isn't functional properly either that or the part it is sending the 'message' to turn on to isn't working.

I have no fault code as one hasn't shown up and as far as I can see the Boiler is working and functioning correctly apart one this one feature.

If anyone has any ideas as to what this could be I would be very grateful to hear as its getting to that time of year again where Central Heating is required and I have a little one to keep warm. Also, if anyone does have an idea what the issue could be if someone could also let me know how much it would cost to fix and how long it would take to fix I would be very grateful.

Thank you very much.

I think the only way to sort this is a site visit, I don't charge for diagnosis, just the repair which I quote a price for before it is carried out.
