I gave a 2004 Sundance Cameo Spa. I have the FLO error code. Heater is not working. I powered the spa off and on, no luck. I replaced the stage 2 filter, I cleaned the pleated stage 1 filter, no luck. I ran the spa without filters, no luck. All pumps are operating normally. With no pumps selected on, circulating pump is running and I can visually watch flow switch close when power is applied to the spa. I pulled out the flow switch and manually held the switch closed, shows continuity. I'm stumped! Any ideas anyone??
