OH flashing

Our 780 series sundance control panel shows OH 113 degrees. The water temp is only 90. Should we replace the temp sensor, flow sensor or temp limit sensor. All jets and pumps are working fine

    Joann, if you have verified with an external thermometer that the temperature in the water is 90 but the topside control panel reads 113 you likely have a bad temp sensor. If all else fails contact your local Sundance Support Desk to book a diagnostic and repair of your 780 series spa.
