stuck on blowout

My sundance 880 hot tub has decided to stay on what appears to be its ‘blowout’ cycle. The control panel appears to have the watchdog set of lines and turning power off and on did no good. Thoughts before I call someone in?

    Joe, the WATCHDOG symbol could be caused by many things. Anything from a bad sensor to a bad PWA to a bad transformer connection. Try unplugging your sensor harness. If the WATCHDOG symbol goes away and you are left with a class SN error msg you may have a bad temp or hi-limit sensor. If all else fails contact your local Sundance Spas Support Desk to book a diagnostic and repair of your Sundance 880 Series Spa.
