Anyone thought about the heating 2 port?

Lock open your 2 ports in the manual position and see what happens. If one or both are not responding and are closed the pump will make a noise and the boiler will go off after a min or two. So check power to pump and if it is spinning if power there but not spinning or weak impellar. Change pump. If no power then check 2 ports are opening and activating the microswitch. If micro switch is activated but no power out then change microswitch. If switch not operated check power to motor if power present then change motor. If no power to motor check room thermostat continuity or power in and out. Power in but not out change stat. No power in then check programmer.

Just seen this. Sorry mate

Hi Harvest Fields.

Apologies if not written correctly. Just trying to explain the situation the best I can.

Do you think if I was to replace both the automated valve on the CH side of things and also replace the thermostat, it may resolve the issue?

Many thanks
