The Flo error code when the system does not detect any water fl ow while the primary pump is running. Check and open water valves. Check for water level. Clean filter.

I already did that. When I unplug and plug in the electrical connector the pump and heater work just fine and there is good water flow. When the system gets up to temp it shuts down like normal. That is when get the FL error code and have to the process.

Ok well that is what the code is for I am not sure why that does not clear it for you but I will opt out and see if anyone else has any ideas.

Usually if you have good flow but get an error the sensor is bad. ( screws into pipe )
First check and clean the connections. If that does not fix it replace the sensor.

Check the connections at the controller also.
You can clean with alcohol

Usually the wire itself is ok but check for flexibility and cracks.

Worst case the control board is bad,
Usually age, moisture , or a lightning pop
is the cause. This is last resort . It is more likely the sensor at the pipe.
