    Hot tub shuts down

    I have a 2000 Sundance Caprio. In the last year I have replaced circulation pump, heater, and jet pump, and temp sensor. Now the unit comes on, but only runs for 2-3 minutes then shuts down and gives a --- code. Any ideas???

    From the Sundance Web Site:

    1. WATCHDOG Error Code: - - - or - - - -

    The most common cause of the Watchdog error code are the sensors, specifically the temperature sensor. When the spa goes into the Watchdog the spa will not operate.
    This is how it happens: When you try to use the spa, you will see 3 or 4 dashes on the control panel (depends upon the model). If you try and reset your breaker, sometimes it comes on but it will probably go back into Watchdog error - - - -. Most common cause for Watchdog is the Temperature Sensor. We have alot of people replace the high limit also and it could also be an issue.

    Because this is the most common issue and one that is the least expensive to replace, We recommend you having a spare set of the Temperature and High limits in case this happens (and usually happens at the worst of times)
    Here is the link for the Temperature and High Limit Sensors: http://www.spaandpoolsource.com/sund...sensors-2.aspx
