My 4 person spa started showing a FLO error. The water level was a little low, so I unplugged it, added more water, took out the filter, and went to start it up again.

It wouldn't start up, and instead the control panel just started flashing.

Called Aquaterra and they said I needed a new control box. I'm wary of ordering a $600 part if that *isn't* the issue.

The spa will not turn on at all other than to flash the light on the control panel. Nothing written there.

I've been using my spa at least 3-4x/week for the past 2-1/2 years. I miss her.

I also plan to move within the next month and am wondering if it's better to move her and then deal with it.

Any advice/tips?
