Mr. Brian

A relative gave me a 1994 Hot Spring Hot Tub Jetsetter Serial # J141248. Its in great shape but they said the motor or pump quite working a few years ago. I have plugged the GFI plug into a 20 amp outlet and I get a flashing red power light on the end of the tub. It does have a key slot and its in the verticle position and I don't have a key to fit it. Do I need a key or is the flashing red light caused by something else. I have not put any water in it yet. Please help me get this puppy running. Thanks, Brian
