I'm trying to confirm the sequence of the operation so that I can better come back and explain the problems I'm facing.
The DHW Pin (the one at the front) comes straight out when the hot water tap is switched on, and retracts when turned off. What is the microswitch it hits actually doing?
The CH pin seems to be up all the time. I've not tested the microswitch manually nor yet attempted to manually push the pin back down, and won't until I have a better understanding of when the pin should be up, retract and what the microswitch is doing.
I understand that internally the valves divert the water flow and Central heating is working, hot water is working, most of the time.
The diverter assembly was replaced with a new unit 7 years ago.
