That is a display error showing there is not enough water flow to activate the heater. Take the filter out of your tub and see if the error goes away. if it does then you need a clean filter. if it does not go away then you have probably have a bad pressure switch.

My hot tub doesn't heat up all the way even though it says it's ready

If a floating thermometer is more than 3-4 Degrees F off what the control panel display temperature then the temperature sensor has likely failed.

The controll panel says flo2 and cool and wont turn on or heat up

Sorry for post before ment to hit the clarification. However, did some checking in general and the FLO2 display says this:

"Closed or shortened flow switch on system startup (system disabled). Flow switch in non-functional. This must only be repaired by a dealer or by a qualified service organization."

I hope this helps. Thanks for using FIXYA, good luck. Jeff
