- HI, I just plugged in my Sundance spa and I’m getting the code FL1 flashing. Even before I hit any buttons. When I go to turn pump 1 on both speeds work. But the other pump wont kick on when you press the other pump button. However the pump 2 will kick on with the initial start up. (so I know it works)
I looked in the flow sensor and it’s not closing, I can see it wobbing but not making contact. I’ve tried purging the system of any air, but no changes. How can I tell if the circulation pump is working correctly? thanks..
