Just been reading your past posts, two questions, did you say that it was a Worcester Greenstar boiler? If so what model and have you got a room stat somewhere in the house? Cheers

No idea why, but Wilo Gold 50 pumps (green in colour), I have come across a few that were suddenly only partly working. Usually the top floor or first few rads heating ok.
They appeared to be perfect, so I assume the motor had lost most of its power. Tbh, I can’t remember if I always checked the rotation direction. I just replaced them and heating working.

Yes mate it’s a green star rsi 24 powered by a Honeywell st9420c thermostat

24 ri condensing boiler sorry

I'm sure he did, but if the system has been partly/fully drained then I'm assuming he vented the heat exchanger in side the boiler after refilling? If so then the next thing I'd do is turn off any rads that are heating to see if the others push through any air. Failing that it's check/replace the pump.

Thanks mate!

Ok so the pump is making all the right noises and these noises change when I move the white thing from 1 to 2 to 3.

Currently got it on 2.

The pump is red hot to touch and one of the pipes going in is too. My radiators though are still cold

How do I know if the pump isn’t working properly when it sounds like it is?

Thanks as ever

What's the pipe coming like (temperature wise)? Is the heat passing through the heating side of the 3 port valve
