Hi guys, before I shell out a lot of money on a new pump that may not fix my problem, I was hoping to get some advice. Originally I had a C-5 Spa controller that kept tripping my 40 amp breaker. I had an error code for the temperature sensor. I unplugged everything except the power, and it stayed on, but when I added the temperature sensor back, it clicked off. This made me think it was the temperature sensor and I replaced two of them but this didn’t fix the problem or the error. I eventually got fed up and bought a new controller, a Gecko YE5. I fired everything up and it seemed to work great with all jets blazing, but I got a FLO error that won’t go away and it won’t heat. I tried removing the filters opening all the jets and bleeding the unions in case it was an airlock, but the FLO error always comes back after a few minutes. The only thing I notice is that pump 2 has kind of a loud hum and leaks a little no matter how much I tighten it. I read that a pump can actually trip the breaker and I wonder if this pump is my problem all along. I’m also wondering if it’s possible my pump has a voltage mismatch given the instructions said I might need to change the wires, but I thought this wasn’t possible given the Jets are working fine. I’m also wondering if it is even possible the pump is the problem because the jets are working. I’ll add video tomorrow. Any advice appreciated. Update from original post: I switched the pumps at the control box so pump 1 is now pump 2. I did this because I suspected the original pump 2 was bad. This is also the one connected directly to the controller while the other pump is indirect. Interesting thing is now the new pump one will not run on low speed. I am going to pull out this pump and check the wiring because the manual said I may need to switch the wire from what I had. Yep I checked the manual and red is supposed to be high speed. You can see in my video that I have black and red switched. I think this is the problem. I have no idea how it was running but I will update if this fixes it. Update: Ok, I drained the hot tub because the valves don’t stop all the water from coming out. I then switched the red and black wires at the pump using the new cables that came with the Gecko and refilled the tub. Think that fixed it. Hot tub started heating right away with no flo errors after several hours. Hope this helped somebody. FullSizeRender.MOV
