I have been battling on FL2 error on my jacuzzi j365. I thought it was because of dirt since water is couple months since winter but I drained and problem persists. I then bought new filters same issue. I remove the filters error goes away. When error comes for mine it causes the heater to run non stop but not to the heating temperature so I usually reset. Error comes back and jets don't work right away but eventually it comes back. I've noticed my filters get tighter even after leaving lose. Did not try hose down pipes yet been cold since one day I was able to drain. Any ideas?
