If you have a Hot Tub FLO Error Code, this usually means there is an issue with water flow in your hot tub.
How to Troubleshoot a Hot Tub FLO Error Code
- Shut down the spa at the breaker
- Make sure there is no debris in the water that can get sucked into the pump
- Take out all of the filter(s) and set them aside
- Turn spa back on at the breaker with the filters out
If the flashing FLO error code is no longer there, your filters are clogged. They either need to be chemically cleaned over-night in filter cleaning solution or replaced if they are 1 year old or older.
If the flashing FLO still appears during troubleshooting, you will need to have a service technician take a look at your hot tub. Something mechanical is obstructing the flow of your hot tub water.
