HOW DO I RESET A WATCHDOG CODE ---- ON A SWEETWATER BALI SPA I TOOK OF THE PROBE AND PUT IT BACK ON AND TEMP READS 130 DEGREES AND WILL NOT GO DOWN AND THE WATER IS ONLY 55 DEGREES .

To clear the error you have to power down for around 20 minutes. Disconnect from power completely for a while.

if it does not clear with a power interrupt - it'll most likely be a faulty sensor - otherwise the transformer or circuit board - a qualified sundance tech will diagnose correctly and fix easily
