    Intermittent FL2 error

    I have a J-335 hot tub that is about 10 years old. It was drained over the summer after we had pump 1 replaced (bad bearings) and pump 2's seal replaced (leak). I started it back up this past weekend, and since then have been getting an intermittent FL2 error code. I tried removing filter 1...
