I have the jacuzzi j 330 hot tub and if I had to do it all all over again I would have never bought this tub. It's been nothing but a POS pain in the arse since the day I got it, (buttons breaking, waterfall breaks, jet's break and won't stay in, have gone threw 3 main control boards, 1 circ pump, 1 new waterfall, 1 new switch valve, 2 top control display boards, and the list goes on and on...) and Jacuzzi has never helped me once!! Since the pool and spa depot where I bought it no longer carries this brand I am completely on my own with this waste of 8 grand!! Anyways, the reason I am here is because (like many others) I too get that stupid FL1 flashing error at least 2-3 times a year! I have since figured out on my own a simply fix and reason for why it happens. *I am assuming at this point you have completely drained cleaned and done a fresh water re-fill... 1. of course check your filters, they really may need mega cleaning or even replaced... 2. check and see if the little straw sized heat out put line is actually pumping water. *if so go to next step.. 3. *THE MAIN FIX and TROUBLE = There is a little grey wire coming from the master control board that is attached to a little (clear see threw) sensor that since Jacuzzi and probably others brands of over priced POS tubs have that need to be simply removed, cleaned, and in certain cases "like mine" you will actually need to carefully bend the flexible metal closer to the magnetic pick-up reader switch. Pay close attention before removing this as to what side or direction the flex metal with attached round magnet is facing!!!... This sensor when working corectly and the circ pump is actually pumping water threw it will cause the flex metal with the magnet to bend and be forced closer to the pick-up reader pole thus closing the circute like a light switch telling the master control board that all is safe and water is pumping to go ahead and turn on the heater. *Yes it's that simply and easy to fix.. and can be adjusted in real time while the tub is running even though when you remove it and put it back remove it and put it back until you get it cleaned and adjusted "just right" water will gush out and you may get a little wet, but no big deal.. 4. Once you've done this cycle threw all the main pump modes and watch and in about 3-10 seconds the little nice red HEAT light will come on and stay on! )) So you are done and it didn't cost you a single penny only a few minutes of your time. I hope this helps others that may have this problem when everything else seems to be fine, Jacuzzi as company is a joke and I will never recomend or buy another product from them or anyone affiliated with them ever again! So yeah, there ya have it, a quick simple FREE fix that most pool repair techs would charge you lots of $$$ to fix when you can just DIY )) Hope this helps.. Happy "repairs -vs- enjoying" you hot-tub with what should have been a recalled product, but it looks like we are stuck with this until we buy a new GOOD better quality Spa/Hot-Tub. djshawn Nashville, TN
