ClintonM Posted July 15, 2022 Report Share Posted July 15, 2022 My new display reads FLO indicating a flow obstruction. I believe this is an issue based on the fact that the two speed pump does not go into low speed on its own? I removed the filter and nothing changes. I can shut off the spa at the breaker and then it resets but a few minutes later it gives me the FLO message (please note that the FLOW switch has been replaced before and it is relatively new.) When the spa was working fine it would engage all of the pumps in succession during filtration cycle to agitate the water. ATM it only switches on Pump 1 to agitate the water. Second issue, Pump #2, a a single stage pump isn't functioning on the button press. I can hear the interlock click when the pump 2 button is pressed however the pump does not start. Pump 1 and 3 do turn on when switched on. Caveats- All of the pumps have been replaced. Motherboard is relatively new. I am attaching the manual to this post. Page 44 is specific to the wiring diagram. 2003_sundance_maxxus_owners_manual.pdf Quote Link to comment Share on other sites More sharing options...
cranbiz Posted July 15, 2022 Report Share Posted July 15, 2022 Pictures of the spa pack, wiring diagram found on the inside cover and pictures of the equipment area, please! The manual is not of any use as it's simply how to wire it to the house supply. We need to see the circuit board and how the jumpers and dip switches are set as well as the actual wiring connected to it. As the main board has been replaced, it could be as simple as a jumper or switch setting being incorrect. Quote Link to comment Share on other sites More sharing options...

ClintonM Posted October 7, 2022 Author Report Share Posted October 7, 2022 Circ pump is running fine but when I hit the control panel above and try to turn on the second pump all I get is a click. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted October 8, 2022 Report Share Posted October 8, 2022 Check the fuse labelled F2 in the schematic, between pump2 relay (T92?) and the pump. Pump2 relay is the black box between the transformer and the main terminal block. Quote Link to comment Share on other sites More sharing options...

ClintonM Posted November 28, 2022 Author Report Share Posted November 28, 2022 I checked the fuse- replaced it with one I know works and replaced the T92 pump2 relay. The pump is brand new and was wired as it was supposed to be using the manufacturer's example. I originally thought it was the pump that was bad but now I guess I know better. Could the issue be the control panel up top? Do you recommend for me to check grounding? Quote Link to comment Share on other sites More sharing options...
