I have a Hotspring Jetsetter (Model J)
The Red Power light is on. the Green Ready light is on until 82F. If I select 83F and temperatures above 83F, the Ready lamp is off. No blinking lamps.
And the water remains warm (after a week it reaches about 90F)
Thanks to Amos' help: We found a fried relay contacts. I fixed the relay board with a new relay. (The old relay still worked and the new one works...)
I checked the voltage out of the relay board: It sends 110V to the heater.
The heater doesn't heat much: Water out of the pump is just warm (~90F) not hot. But not completely cold.
The 2 LED on the controller board are on (LIM OK & HEATER ON)
I measured the resistance of the heater and I found 0 Ohms! (I was expecting 9 Ohms... R=V/I. 6kw)
But I plugged the heater directly in the 110V with a cord I created: The breaker did not trip.
What do I check next? The High-Limit Thermistor?
Thanks for your help
