Code 91 beeps even when my salt readings are 3200 PPM

I suggest you clean the cell according to manual and try it then. If it keeps producing chlorine then keep swimming. If the pump is flowing water fully (if not clean baskets and filter) and it can't keep the chlorine above 2 ppm and you have 30 to 50 ppm stabilizer in the water then there is a major problem in the chlorinator. I don't trust the salt indicator on some chlorinators but that is less important than if it chlorinates. You can but salt test strips. I hope this helps.

1st... Check your salt level consentration.. If okay... 2nd, Check you electrolytic cell, may be plugged with white flaky calcium stuff. The white calcium build-up on the cells will cause a low salt alam.

Code 93 = Good News for You! :-D It is your Saltwater Chlorinator's way of letting you know that it is working properly and your pool's water has a level of salt that is optimal/good.

Code 93 just lets you know it is not actively converting salt to chlorine...it is in 'standby mode.' When you first programmed the number of hours you wanted it to run (by pressing the left (down)arrow until you heard the beep, then pressing the right (up) arrow until you heard the beep - then pressing up until you reached the desired number of hours you wanted the unit to operate (minimum 1 hour, maximum 12 hours)) the unit began converting salt to chlorine immediately.
This is good news for you. Once the number of hours of operation are up, your unit will give you a code when you press either button. If your salt level is too low, you will receive code 91 indicating this, if your salt level is too high, you will receive code 92 indicating this, if the water flow is too low, you will receive code 90 indicating this (this gives you the opportunity to correct this before the next cycle begins. If there is no error with your pool's water, your unit will go into standby and wait until it is time to run the numbers of hours you programmed it for (it will begin it's cycle at the same time each day unless reprogrammed by you). When this happens, you will find code 93.

So, just to recap:
Code 93 = Good
Code 92= Salt level too HIGH (Empty approx. 20% of pools water & refill with fresh water.)
Code 91 = Salt level too LOW (Add salt.)
Code 90 = Low Water Flow (Check your filter. If it is working properly, you may find that it is too small for your pool. The filter that came with my pool was FAR TOO SMALL - I spent more time cleaning the pool than swimming in it. My 18' x 4' pool came with a 1500 filter. Now, I have a 4000 Sand Filter. This + the Saltwater Chlorinator = practically no maintenance. Together, these were approximately a $500 investment. WELL WORTH IT!!!)
Code 88 = Startup mode. (Press down arrow until you hear the beep. Press up arrow until you hear the beep. Press up arrow until you have the unit set to operate the number of hours you desire.)
As an extra FYI: The unit works with the sun. This means the unit turns the salt from your pool into natural chlorine which is then sent back into your pool. The sun turns this natural chlorine into salt. Your filter sends this salt into your saltwater chlorinator where it is again converted into natural chlorine & returned to your pool where then sun...I think you get it. ;-) It's a continuous process. ~This being the case, when you program your saltwater chlorinator, it is best to set it up to help it work with the sun rather than setting it up to compete with the sun. You do this by programming it to run at night. This way, your unit isn't working hard to generate chlorine at the same time the sun is diligently converting the chlorine to salt. I've read several articles where people argue that you should run your saltwater system at night & your filter during the day. I don't understand this concept. My filter runs 24/7 & my saltwater chlorinator runs 12 hours - from 8pm to 8am. Since I set my pool up to operate this way, I have not had to clean it at all other than backwashing the filter every other month just for principle. My water is crystal clear.
One further note of interest: My pool holds approximately 6000 gallons of water. For this, Intex recommends 135 pounds of salt. Because of some advice I'd read posted by other users, I started with only one 40lb bag. This was all my pool needed. Approximately once/year, I add one more 40lb bag.
RJBALLZER777, because you are receiving code 93, I realize you have set your pool up correctly and, therefore, are possibly thinking, "Why is she telling me all of these things I don't need to know?" I apologize if that is what you are thinking. I am really posting for those who have not gotten it just right the first time (or who are doing their research before buying as I did) so that they may get several questions answered at once. Hope you don't mind that I used your question as a means to post. (That's why I answered your question right off the bat.) Hope this post helps some.

what is the ppm of your salt
and are you using a test kit that reads salt in #'s or color dip strip

code 91 is low salt
do not just guess at it! even the recommended amount in the manual is just that, a starting point
It is up to you to fine tune it

Get a salt test kit that reads in #'s not color
Now get your pool to as close to 3000ppm as possible
under 2700 will cause the system to not produce enough chlorine
any higher than 3500ppm and you can go cloudy, trigger high salt alarm, and even taste terrible
Here is a link to manuals so you can see all other codes

how long did you filter before trying to generate chlorine also you say salt is at what it should be what is the ppm

Yes, and be sure to keep up with your pH as it will want to rise slowly over time when using a salt water chlorine generator.

hello our pool chlorinator keeps comming up low salt 91 no matter how much salt we put in this is frustrating why is this happening ,,,please help
