Have you ever tried CC tee's Jon ?
If not this one sounds like a Rubbish or bust chance to try it out if you haven't, although I understand space under / around boiler at a premium.
Should be a days money, new system pump, few fittings, bit of tube and simple wiring mods. I bet it would transform the circulation around the rad's.

Pump too small 25-80 pump needed

Also bet the expansion vessel is too small around 20 l needed

In most properties expansion vessels are too small.

Long long time ago Chris , I know how it works and the principal behind it , only thing I wouldn’t be 100% wiring in the other pump with this boiler .
I do agree it should sort it ,but as I said just a few checks to make first .
Then if he goes for it , a load of plasterboard will have to come down and the old washing machine will need a new home .

If it is a system boiler with S Plan, just feed new system pump from the SWL, so it runs whenever there is a demand.

Cheers Gotch ya . I did some CCT’s on a Viessmann and they made a separate box to wire it in to “if memory serves “

Could be an air lock. Rubbish all rads except those not working. Then attach to hose to hopefully a drain off on or near rads. Open filling loop and build up to 2.8 bar pressure. Then open drain off and filing loop simultaneously. Hopefully this will force any air out. It might also dislodge any blockage that may be in that particular leg.
