I have a older hot tub, was leaking really bad. I drained the tub and fixed the leak. Refilled tub.. but now I get a FL code. I've tried a New filter, New Flow sensor, forced water in the filter hole, heat holes.. but the Code only clears for a minute, as soon as I remove the hose, codes again sometimes goes into OH code, shuts down... On my sensor I'm not getting any shock when I touch the wires, but no blown fuses
