Good morning 728
Not a heating guy, but it sounds like the pump wants checking out.

Don't know this boiler, but is it a combi or heat only?

If a combi it could be the diverter valve stuck, if heat only could be the ch zone valve not opening.

hi
this is a combi boiler and it is heatline , the thing is when the central heating is on the pipe coming out for ch is hot around the boiler

Take the diverter valve motor off and manually hold in the pin which is exposed and see what that does!

Are you in Foleshill ?
