I came home the other day and noticed my hot tub had no power, or appeared to have no power. I went and checked the breaker and it was fine. I reset it just to see if the hot tub would power up, and "560" flased on the readout and nothing else happened. It completely dead with exception of the 560 and i cant find anything about it. Retailer where I bought it wants $150 just to show up.
