hi there, our hot tub started flashing the watchdog symbol. When we turn off breaker and then back on, it quickly flashes “ice” then back to watchdog symbol. Any tips. Thank you.

    Marty, many things can cause Watchdog. Poor flow and an overheat situation, poor connection at your PWA, bad temp and or hi limit sensor, bad PWA, bad control panel, bad transformer. Check your primary and secondary transformer connections to the PWA that they are good and tight. You could also trying changing your temp sensor if your connections are good. If all else fails contact your local Sundance Support Desk to book a diagnostic and repair of your Sundance Optima Spa.
