Lefty P Posted June 17, 2022 Report Share Posted June 17, 2022 Sundance Chelsee 780 series spa going into watchdog mode (---) I drained my tub and replaced both filters and the UV light.....refilled and powered up Continuously tripped the circuit breaker. I disconnected the heater and the tub ran fine (minus having a heater) I replaced the heater an the flow valve Powered up and it seemed to be fine....next morning was in --- mode .......temp was 114 degrees f (checked with IR temp. sensor) After cooling down disconnected heater and it seems to be fine (without the heater) Any help on next steps would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
