OK then that's your problem then, just confirm that the CH and HW are both off??Yes yes yes, you are right, if I touch it, then power is back on!!!

No, but if you are referring to my power issue earlier, I have power only when I reconnect the orange wire back to systemDid you put any demands on?
What?? It itself is a problem???OK then that's your problem then, just confirm that the CH and HW are both off??
Sorry, I did that, so i did measure 240V between the removed orange and the earth/neutral, while the connected orange in the box are reading 0V.Yes, that is the problem, IE your M.valve is still sending a signal to the boiler/pump to run even though he M valve isn't getting a demand to open from the relevant system so needs renewing, more than likely just the actuator which doesn't involve draining down the system.
Why didnt you probe between the removed orange wire and earth with power on but both CH & HW off, it should have read 230V.
I get it now!!!!!Have never replaced the motor only.
"Still trying to understand how my system is not powered up without having it to reconnect back."
If you mean boiler/pump not running then its because there is no demand because you had removed the orange wire from the faulty M.valve, if you leave it disconnected and create a CH or HW demand then the boiler/pump will start up, is it a CH or HW M.valve thats faulty?.
Yes, it’s not the motor at fault, it’s a microswitch.so I have swapped the synchron motor from a good one to the faulty one, it does not seem to help with the voltage, it still registers 240V.
So I need to replace the whole M. Valves?
