I have a Thermospa Olimpian Made in 2004, 230 volt cicuit, Balboa 2000 D-DCA controll panel, 2000D top side electronic control. It has 2 inch stainless elec heat, 2 jet pumps with main pump motor, is 2 speed. Also has blower motor. Main pump is stuck on low speed along with a constant FLO code. Can shut down elec, start back up, place in standard mode to get heater and all things to work, but never high speed in main pump. Always stuck on low. Gate valves are open, has new filter and has new pressure switch. Nothing has helped.

If you have a secondary control switch on the oppisite side of your hot tub try dis connecting it.
