I have a 2007 Hot Springs Prodigy spa that I purchased used. It work perfectly when we went to purchase it. When we got it home and all hooked up it has a hard time starting up. When you push the jets button it try's to come on but it makes like a surging sound (on and off). It does this sometimes for two or three times and sometimes longer before it will start and run fine. I had this plugged into an undedicated line and thought that might be the problem so I wired it to a dedicated line and that made no difference at all. Any Help would be greatly appreciated!
