i have a Jandy RS8 and in auto mode it keeps turning on the spa (spa is definitely not programmed to run). Everything works fine is service mode. I tried turning off system power and hitting the reset button but neither worked
You nailed it. I disconnected the spa side switch at the control unit. Started in auto mode and the spa came on immediately. Hit the reset button and that took care of the problem. Cleaner and pump came on as programmed in auto mode. Thanks.
Along with electrical, I have serviced, repaired, and replaced pool and spa equipment since 1992.
