Heater is displaying Flo code. Not sure what I need to do

If this is happening when the pump is off but the heat pump has power, it's detecting no flow. If this is happening when the pump is running, the heat pump may be detecting low flow. The usual cause of this error code is a dirty filter. We would recommend cleaning the filter to see if the code goes away.
