Thanks everyone! Ended up being a dead circ pump. Replaced the circ pump and I'm back in business!

Hi! Went out to my 2002 Sundance Altamar hottub today and saw the FLO alert flashing and the 2-speed pump running on low. Shut off the breaker and cleaned the filter to see if a clog was causing it. Restarted (without the filter) and the FLO alert came on about 5-10 seconds after turning the power back on, so it doesn't seem to be a filter issue. The high-speed pump and air bubbles work fine. The 2-speed pump jets are not blowing hard and I hear a gurgling/airy sound from the tube that leads to the lounge jets. Each time I power the hottub back on, the FLO error comes on within seconds. The opening where the hot water normally comes out is BARELY flowing when the low-speed pump is running. From poking around on forums, it seems like the flow switch and circulation pump seem to be common culprits. Any ideas of what I should do first? Thanks much!
