I have a different problem to what is describe above and hope anyone would be able to help me. My pump is not running so my geyser functions as a conventional geyser with the element being the only heat source cause the water does not get pumped to the collector. I noticed that when i disconnect the collector probe then the pump is running. the spanner indicator also lit up green but it gives an E8 error on the Geyserwise showing a fault with the collector probe because I disconnected it. When I insert the collector probe back than the Error E8 disappears but the pump stops then. Any help on how to fix this would help. The temp differential between Solar collector and Geyser temp is set to 7degree Celcius. Any idea of how to fix this problem or what could cause it.
