I've got a 18 year old Seven Seas Spas hot tub that is in great shape. I got it off a guy remodeling his house and he just wanted to get rid of it. The heater was built into the controls and both were burnt up, so I bought a spa pack from the spadepot.com. It is a 240v top mount air controlled new out of the box. The problem is that when I hook it up to the motor and turn power onto it, the pump makes a loud nasty sound and quits. I hook them up separately and the pump works fine, but I can't hook them up together. Any ideas on what my problem is?
