My unbranded swim spa has a SmarTouch control that is stuck on CAnC. I have flipped multibreaker, Flipped GFI, tried pushing every combination of buttons in the manual. A spa repair maintance company I use sent a man out, then called me to tell me the Controller pack and controller need totally replacing for $2100.00, which includes $1000 labor. Does this sound right? I am apalled. Thanks, Sylvia
