'Fl' means that there's insufficient flow of water through the heater, or non at all.
1) Check the water level - top up if low. 2) Ensure that all jets are open and flow water - if they don't you may have a pump issue. 3) Remove the filter(s) and see whether or not this clears the fault, if so clean or replace the filters.
