Curious if you managed to solve this. I'm also having the FLO error with the same setup. Found a blown fuse, replaced that and everything ran fine for one use and next day fuse blown and same error

Having the same error. I found the 20A fuse to be blown and replaced it. Everything worked fine for one spa use and then the next day fuse blown again. Guessing a short or bad pump is causing fuse to blow
