Just recently purchased a Used 05 Artesian Antigua Spa. When I started up tub (a few days ago) the water temp has been stuck on 95 the entire time. U can adjust the water tempature and the other night when it was aabout 55 out I had tub at 95 and tub was about 106 next day set at 85 had temp at 95 now it is 45 out and water temperature is 85 no matter what I set tempature too. Im assumming heater is fine and that my issue is with a limit, relay, thermostat, or contol board. Someone that can lead me in the right direction would appretiated. Thank you for your time.
