Central heating issue on Logic Combi ESP1 35

[MrDave]

Hi,

I noticed the pressure this morning on my boiler was just below 1bar so I went to top it up, opened the loop and it just managed to hit over 1bar then just stopped increasing.

Now the central heating looks like its on but all the radiators are luke warm even when temperature is 70 degrees +

Boiler is a Logic Combi ESP1 35

Any ideas what this could be?

Thanks in advance

Could be a few things, such as diverter valve, weak pump, etc.

You shut the wrong valve?

All sorted, I bled the radiators a little and tried the fill loop again and its all working. cheers for the replies
