HAVE A BALI SPA THAT WENT TO WATCHDOG CODE ---- SHUT DOWN POWER BUT CODE KEEPS COMING BACK.UNPLUGED SENSORS AND PLUGED BACK IN SAYS OH THAN GOES TO 130 DEGREES AND SHUTS OFF AGAIN.WATER TEMP IS AROUND 50 DEGREES .IS IT A BAD BOARD OR A BAD SENSOR OR ???????? ANY HELP

To clear the error you have to power down for around 20 minutes. Disconnect from power completely for a while. It could be a flow issue, lets clear the error and go from there....

SHUT POWER OFF AND IT GOES THROUGH ITS BOOTUP AND GOES TO 130 DEGREES (WATER IS 50 DEGREES)THAN IT GOES TO WATCHDOG CODE RIGHT AWAY. ? IS IT HIGH LIMIT PROBE OR A BAD BOARD.ANY WAY TO CHECK HIGH LIMIT PROBE.

THANKS

Could be the board or the temp sensor. I would go for the temp sensor first since it is less expensive than a board. We sell them, I need the year and model of the tub to identify the sensor.
