error code

I had a watchdog code, you folks recommended I change the temp sensor and it worked. But then I had a “PLuG” code after about 10 min. I tried unplugging the three cables one at a time. It wouldn’t run with temp unplugged, nor the hi limit, but it ran for half hour with the flo switch unplugged, but flashed “flo” the whole time (makes sense). When I reinstalled it, it ran fine again for 10 minutes then flashed “PLuG”. Thoughts?? Bad Flo switch??

    Marty it sounds like you either have a bad connection to the PWA at the sensor harness or you have a bad PWA. If all else fails contact your local Sundance Spa Support desk to book a diagnostic and repair of your Sundance Spa.
