Hello, I just got a used LA Spa and am havome some trouble. The low speed pump will only stay on for about 90 seconds, and when you switch the high speed pump on it shuts everything down immediately. Once the low speed pump shuts off you have to wait about a min to get either to turn back on. I hear the clicking when the buttons are pressed. So, I believe that the relays are working properly, I just don't know why it would shut down like that. I hope that I am providing enough information for someone to help me out.
The Spa is a 2004 LA Spa with an Advanced Spa pack # DS-404. Single pump, air operated topside.
