Undid the pump screw and checked it, it was spinning freely
Then I looked down and spotted the problem.
I forgot to open the tap on the central heating return :roll: :oops:
Hi folks, I'll try to give quite a bit of detail to aid clarity...
I have a C24 which, after about 3 years of use, gave out when the diverter valve failed due to a water leak. This shorted the diverter motor. I believe this is a common fault.
The plan was thus: Buy service kit/new motor...
