Surfbeast Posted August 29, 2008 Report Share Posted August 29, 2008 I recently had a "FL" code pop up, (constant on). Could this be a clogged filter or is it more likely a bad flow switch? Any idea where this switch would be located ( general area ). Do you just unscrew it and put a new one in? Thanks, 2000 Dynasty Trevi spa.

Yes it could be a clogged filter remove the filter and try running it. it could also be the pressure switch which is behind the heater and under the circuit board on my tub. my pressure switch screws in and has two wires from the board to it. i would imagine it has to be drained before doing this. another idea is bypassing the pressure switch if you still get the fl reading then its your filter a clog or circulation pump i am also new to this and only know this information from reading the forum. The only thing i have experienced is bypassing my pressure switch, which has not solved my problem so i am still learning lots. perhaps this wil help Quote Link to comment Share on other sites More sharing options...
