tommyspahunter Posted October 7, 2023 Report Share Posted October 7, 2023 I replaced Circ pump, checked all connection CLA D-17 red, Limit switch Green, Heater led Red. When jets are not on or on low i get the flashing READY and Power blinking. Jets on high its operational and heats. Stumped! Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted October 8, 2023 Report Share Posted October 8, 2023 Remove filter. Check for good flow from the circulation pump and lots of tiny bubbles from the footwell. Post pics of equipment area, circuit board, and wiring diagram. Quote Link to comment Share on other sites More sharing options...
