I have a 2004 sundance/sweetwater hot tub. I have just replaced the temp sensor as the tub was reading 106 to 108 degrees and was actually like 75. I put the new temp sensor in and it started to work and read the temp as it should. It went from 65 to about 90 with no problems and continued heating. When I got up in the morning I checked the tub and was only at 89. I then shut it off and started it a few minutes later and it began to operate as it should it heated it up about another 4 degrees and the heat then shut off again. I reset it again and it repeated the same thing. I currently have the tub heated to 104 using this method but it will not maintain the temp. Any suggestions

Jason, make sure your filter cycles are set to F3 and that you have 60amp service and your PWA is set for 60amp logic. If all else fails contact your local Sundance Spas Support Desk to book a diagnostic and repair of your Sundance Spa.
