Hi, my name is***** have been in the plumbing & heating trade for approximately 15 years. I will be helping you today.
What is the water pressure in the system please.
This is quite often due to an airlock, but could be the water pump stuck or failed. when you take out the screw in the middle of the pump can you tell if its running?
