HRZNJB Posted September 30, 2021 Report Posted September 30, 2021 (edited) My Coast Spa is nothing but trouble. Today's issue is that the system is reporting that the Heater is Too Hot. But the system has been in rest mode and low temperature and the water is cold. The B sensor was reporting hot so I replaced that sensor. After which both sensors seem nominal and in sync. Shortly thereafter the A sensor reports hot. Then the B sensor reports hot. So neither stable nor in sync. I have unplugged the sensors and rebooted. But the system is rebooting to a Heater Too Hot status. I suspect now a logic board issue (which would be my 4th board in 6 years). Thoughts or suggestions? And now it will not poser up even to the Heater Too Hot status. Instead, all LEDs blink. Edited September 30, 2021 by HRZNJB Updated information Quote
