I have a 2002 Sundance Altamar that I got from a customer of mine. I replaced the circulation pump before I even turned on the tub. I start the tub for the first time and I am getting a FLO code. Here is what I have done, I’ve made sure to the best of my knowledge bled all the air from the system, I have removed the main filter, and I have replaced the flow sensor. Nothing has been able to remove the FLO code. It is flashing the FLO code between the water, temp, and cool signs. The other two pumps and the circulation pump work like they are supposed to and seem to run fine. I am asking on here before I decide to call a service tech.

Did you install the new flow switch in the right direction? When the circ is running the toggle in the flow switch should get pushed up against the post making a connection. Verify that it is making the connection. if it is making the connection but you still have a flo error you could try to jumper the flow switch but you will need to verify that the circ is flowing water.. or disconnect the heater from the board for testing so if the heater engages and there is a flow issue it won't go nuclear (only takes a split second to get really hot). I recommend disconnecting the heater for testing.

Is the new circ the same voltage as the original? (120V or 240V)

Next I would be looking at and testing the sensors. See page 55 below for resistance chart

I figured out the issue!! The red wire from the flow sensor had gotten slightly pulled out of the sensor bar on the control panel. After resetting it to where it is making contact with the pin, the tub is now heating and throwing only the cool code (water temp is 56°). Thank you for the help.
