Hot tub heat

Our Chelsea hot tub is not heating. The heater light indicator on the panel is on. The circulating pump is running. The water was at 102 and has now gone down to 85.

    Hi Jeff. If the indicator lite is on your topside control panel is working to some extent. You’ll want to check the area where your main circuit board is for signs of burnt wires or burn marks on the board. You could have a bad board and or bad heater. Be sure to protect your equipment area with a space heater on low speed until you correctly diagnose and repair the heat to your spa. If all else fails contact our Sundance Service Support Desk to provide a diagnostic service call and or Hot tub winterization.
