Logic combi 35 issue

Hi all.

I currently have hot water but no heating.

Pressure is fine, although it does seem like I have a very slow leak on the boiler and a week ago I did come home to 0 pressure. But right now, pressure is ok, in fact its at 2 which may be a tad high. But it was a little lower (1.5) earlier and still wasn’t working.

The clock hasn’t kept the correct time on there in a long time, it would always be out of sync after a couple of days. However I did try setting the timer this afternoon which was the first time in a few months and so seems like quite a coincidence that it is has now stopped working.

I’ve got it in the correct position on the settings, in fact I’ve flicked back to constant and of course tuned up my thermostat, which is how I normally use it.

I’ve tried resetting and turning off at the wall.

When I have the thermostat turned up, the boiler does show “c” which means it’s recognising the demand for central heating, but none of the radiators are warm.

Any suggestions?

Thanks.

Proper boiler service would be my first port of call
Once that is done, fault the sequence to find out what is amiss

Regularly see boiler that have been serviced yet front has not come off the boiler

check you haven’t accidentally turned off one of the heating valves (Black ones left and right hand side) when you repressurised.
