postman454 Posted March 13 Report Share Posted March 13 We have a 2016 spa that keep getting an over heat state. The spa has a 220v circulation pump that I thought was the problem but after replacing it we still have the problem. Even with the heater on rest mode and the heater set to low, temp set at 99F it is still overheating (110-115F). Filter is clean and new, all valves are open. Circulation pump is set to run 24hrs as by design. Filtration mode on controller only set for 15min. Circulation pump seems to have good flow out of the 3 bottom outlets and the water fall. Ozone is new and working. Jet pumps are not running except for their 1 min purge every 6hrs. not hot outside. heater and temp sensors all check out. What else am I missing or what else could I check? Can a bad circuit board make the 220V 1/15hp circulation pump run hot and put heat into the water? I have tried to check temperatures of piping with a thermometer gun before and after pump but not getting great readings as its on the outside of the pipe. 2016 Wind River Spa Laing Thermotech circ pump E14 Balboa WRBP20B, part number 5611 with Spa Touch controller Quote Link to comment Share on other sites More sharing options...
