Jacuzzi hot tub model J-300 series with an FL-1 code. I have shut off power at box and restarted a couple of times and the circulation pump reset. Now the reset won't happen. Both pumps still operate and I have pulled the filters and cleaned them. Tub is outside and temp has been single digits for the last 10 days. Any suggestions?
A flashing “FL1” display means the flow switch is malfunctioning open, the filter cartridge is excessively dirty or an “air lock” condition has occurred at the circulation pump intake.
