Why is my KZN Solar Heat Pump pump noisy and not cycling water?

If the KZN Solar Heat Pump pump is working but is too noisy and the water isn't being cycled, it could be due to several reasons. There might be a lack of water in the system, so check the water make-up device and fill it with water. Air in the water circulation can also cause this, so discharge the air in the water system. Ensure all valves in the system are open. Finally, check for filter stoppage and clean the filter if necessary.
