Cold tap valve has overtightened so trying to get to it... and failing.
I've removed the end cap, and the screw inside but still can't remove the handle. There is a couple of mm play in the handle when I pull it out but then sticks firm. There is no grub screw anywhere on the handle shaft...
I recently had a Nest 3rd Gen installed by a Nest Pro to my Greenstar 37CDi Combi gas boiler.
The Nest itself is working perfectly but the pump is constantly running 24 hours a day.
Worcester have not been able to make any suggestions and the Nest Pro Installer & Nest have also drawn a blank...
