teamblair Posted October 23, 2010 Report Share Posted October 23, 2010 We have a Sundance Chelsee series 780 spa and the power has turned off. When the breaker is reset an error code 356 comes up. We just noticed that there is water in the stero on the top of the spa. Could this be what is causing the spa to turn it's self off? Or is there something with the mother board that needs to be replaced? All the service departments are closed today and we really wanted to use the spa this weekend. Any help you can give would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Spa_Guru Posted October 23, 2010 Report Share Posted October 23, 2010 Water on or in the stereo won't cause it, I am not familiar with code 356, does it come on and stay on?

teamblair Posted October 23, 2010 Author Report Share Posted October 23, 2010 The GFI breaker keeps tripping and no power at spa. We disconnected power at spa control box and GFI breaker stays on, but if we hook power back up to spa breaker trips. spa worked great last weekend, we use it weekly.

You have a ground fault somewhere in the tub. Usually, it is a heater or ozonator (if equipped). Do not keep putting power to this particular board or you will damage it and dramatically escalate your repair costs. The proper method of ground fault testing is to isolate each load and ground fault test with a megohmmeter. The 356 is NOT an error code.
