Hi,
I have a 2000 Hot Springs Landmark spa. The spa was up to temperature showing the green temperature light along with the red power light. The filters are clean and there "has not" been a power failure. This happens with or without turning on the jets.
Does anyone know what would suddenly cause the red power light to begin blinking? This has happened numerous times before. The power & heater electrical breakers "are not" tripping. The only fix I have found is to perform the following steps;
1) Turn both breakers off (Power & heat).
2) Wait five to ten minutes and flip the power breaker on.
3)Wait another five to ten minutes and flip the heater breaker on.
Sometimes I have to repeat these steps in order to get it back to regular operating status.
Once corrected, everything would be fine for a couple days and then for some reason the power light begins to flash again. I'd like to add that I have upgraded the factory heater assembly, Thermistor, Control thermostat & Thermistor, Spa high limit back in May of 2008. Your help would be most appreciated. Thanks, Ray
