I have an Artesian Spa Grand Bahama that I am having a heating issue with and am not sure where the problem could be coming from. The spa is at least 8 years old as I’ve lived in the house 7 and the previous owner put it in a couple years before.
it’ll run fine for a couple days, but then every few days when I go out to it the circulating pump won’t be running and the display will just show - - - for the current temperature. The weird thing is there is no error code shown (in the past I had an overheating g issue that would then have the heater shut off that the just kinda went away after a week). If I touch any of the buttons on the controls (a jet button, the lights, or any menu button) instantly the temperature then reads the current temp and the pump and heater turn back on.
Does anyone know what the cause t could be that is causing g the pump to turn off and the temp to read dashes, but then come right back on if I touch any button? I’m really kinda stuck here, don’t know what parts I should be looking into whether the temp sensors or what. I already replace the circulating pump once about 6 years ago when it seized.
