Hi, hoping for some help with a "FL" flow switch error.

Are fairly new owners of used 10 year old Catalina Bel Air Limited Edition spa. It has the Balboa CAT 100 spa pack and 3-button topside controls, single pump system, ozone, but no circulation pump. Had been working perfectly until we changed the filters yesterday, which were pretty dirty after 2 1/2 months and came with the spa so I don't know how old they were. We did clean the used filters 3 months ago when we installed the spa, but again, I don't know how old they were. The system uses (2) screw-in cartridge filters, which I purchased from Spa Depot online.

After replacing the filters while the spa was full as normal, I circulated the water with the pump on high to clean out the debris that fell into the water after removing the old filters. Worked fine until I turned the pump down to low and noticed shortly afterward that there was no water flow and the topside panel said "FL", solid on, not flashing. I turned off the breaker, turned it back on and it worked fine, until later after the pump came out of high speed, should have been on low to heat and circulate. We were able to use the spa, but same thing after turning it on low, it wouldn't come back on without cycling the breaker.

Water temperature was good at 100 degrees, jets work normally, and water flow into the filter seemed a little better since changing the filter. We did notice that there is less suction on the lower suction fitting, which we assumed was due to better water flow through the new, clean filters. This morning, the spa was 94 degrees, and the solid FL code was back, even though the pump was only on low speed overnight during the 4 hour circulation and heating cycles.

Could this be due to better water flow through the filters and perhaps the computer is detecting this new condition, causing the error code? Can the flow sensor be adjusted? Could there be air in the system after changing the filter, even though I changed it while the spa was full? Could there be debris in one of the pipes near the sensor, and if so, can it be flushed out other than normal operation? Should I put the old filters back in? Does this have anything to do with changing the filters?

Any help would be appreciated. BTW, my husband is an Electrician and can troubleshoot any wiring issues, though he has not worked on spas before. Just trying to help him out since he's a busy guy right now, and we have some cold weather in the forecast, so looking to avoid freezing problems.

Thanks!

Take a look at your flow sensor. It should be in the pipe just past the pump before the heater tube. Screw it out and look at it to check for debri. Maybe it has failed.
