How to troubleshoot Jacuzzi hot tub flow switch?
Simple Jacuzzi J-300 Series Flow Switch Troubleshooting One of the most simple ways to diagnose a FL 1 or FL 2 error code on your Jacuzzi J-300 Series hot tubs is to just do a visible inspection of the flow switch.
What does it mean when your hot tub says flow error?
A hot tub flow error indicates that there is a problem with the flowing of water through the hot tub heater. Some of the most common hot tub error codes are FLO, FL1 or FL2, and are picked up by flow or pressure switches.
What’s the difference between Flo and FLC on a hot tub?
They’ll come off your top side display. One error code is FLO. The other one is FLC. Flow switch open, flow switch closed. The purpose of your pressure switch is to measure pressure in the line when your pump is running. So your pump comes on low speed.
What does it mean when your hot tub pressure switch is open?
On some Balboa systems, the FLO error message alternating with current temperature readout means the pressure switch is open. If the switch is open, the spa will not heat as it is not sensing proper water pressure in the heater tube. First try to power down and restart the spa. Maybe the problem will magically disappear!

How does the pressure switch on a Balboa hot tub work?
Newer style Balboa M7 systems have 2 sensors built into the heater tube that monitor temperature and high limit functions and eliminate the need for a pressure switch on those systems. How the pressure switch works is that it changes between open and closed depending on water pressure.
