Hi, I’m getting repeated FL1 error codes on my Hawthorne Sundance hot tub. Sometimes cleared by powering down then up, sometimes cleared by filling the tub to max recommended. When I clear it the hot tub will run until the water is re-heated, then will come back. Can’t find leak in system. How do I distinguish between a leak in the system, and a bad pressure switch?

Hi Matthew. Sounds like a dirty filter. Try removing the filter for a brief period ie 15min and run the system without to see if the FL1 message goes away. If it remains I would suggest you contact our Sundance Service Support Desk to book a diagnostic and repair of your Sundance Hawthorne Spa.
