Same here, been getting the 91 code, 3 times in last 1 1/2 weeks. Added salt. Came on today, so I checked titanium plates and they were half clogged with white stuff. DO NOT ADD SALT just because 91 code is on, which I have done. . You need to check plates and clean if clogged, with hose and some pressure. I used a plastic wire tie to clean, do not use metal item to clean plates, you'll scratch the plates and ruin them. Mine was clogged on 2 plates full length.

Pump goes into sleep mode because of low salt light. I have added 240 pounds of salt since the light came on and fell that I may be haveing other problems. Would it be normal to have to add that much salt...


No more salt for now!!!!! 1st thing you need to do is check your salt ppm.. must be around 3000ppm.. The 8110 models have issues with their cells that will continue to give you a low salt reading regardless of the salt level.. You must check the cell for calcium build up and clean.. You can soak with vinegar or as others recommend, muriatic acid to clean the cells. Pressure flush to get all the "White Flaky" stuff out.. Dirty cells WILL give you a low salt error on the unit.. If after cleaning the cells you still get this code, you may have a bad cell.. If you are just starting out and the unit is new, YES you will probably add over 300 lbs of salt to get you going and be around 3000ppm on a 14000 gallon pool... Be sure to run your pump only for 24 hrs to properly dissolve the salt and then set your cycle...
Hope this helps...

What is code 91 on intex 8110 model


This is the code for "Low Salt"... Could mean two things
  1. Low Salt and will need to test ppm and add to target 3000ppm
  2. Dirty electrolytic cell, soak with vinegar and flush clean..
Hope this helps!

Once a week I've been adding salt (80 lbs) to my pool and again get low salt code (91)....it has been very unusually hot (HTX 110) is this causing the problem and I need to add more?


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.

I have done everything the manual says, but my saltwater system will not stop blinking error code 91. The salt level is fine, and the cell is clean. Do I need to replace the cell. My pool is now green and...


Bummer!!! Looks like you checked both things that would cause the code 91 error for "Low Salt". Here's what I've done to solve my low salt "91 code in the past.. I overshoot by 1/2 bag = 20lbs of the recommended salt add quantity when the code appears. Calculate by using this formula..
.0067 X Pool Gallons. I have a 14,000 gallon pool and when I get the 91 code for low salt, I add about 110 lbs of salt. Manual says 93 lbs...let it circulate for 24 hours by running the pump only and then start the chlorination cycle.. Before doing this, you MUST make sure the cell in clean.. If any calcium buildup inside, it can give you a false "Low Salt" alarm.

I hope this helps!!

If this helps, please rate... Thanks

My pump keeps reading low salt it will run fine for about 2 to 3 hrs then the low salt alarm goes off. I have put in approx 240 lbs of salt I have at 16' x 48" pool. Please help


Your unit is malfunctioning...your pool @ ~5200 gallons, even from a no-salt in the water start-up should only need ~140 lbs. Are you certain it is reading low salt and not high salt or simply salt error? You can try diluting the water to get the salt levels below 3600, otherwise you need the unit serviced or replaced...generally with an intex, if that is what you have, it will mean replaced.

Constant code 91! after only 1 week my first chlorinator was replaced due to this code. Have been using my replacement for approx 2.5 weeks and got my first code 91 - added 1 bag of high purity pool salt...


Hello,
A few things to do or you will create your own problems.

First and for most you must filter for at least 12 hours after adding salt to distribute the salt completly

You can not just blindly ad salt like you said you added a bag.

Although the manuals have an amount of salt for different size pools it is just a starting point. It is up to you tp fine tune

you must get a salt test kit
the kind that reads #'s not color

Get your salt as close to 3000ppm as possible
any lower than 2700 and you will get a low salt alarm and you will also not be producing enough chlorine
any higher than 3500 and you can go cloudy, trigger high alarm, and the water will taste nasty
you can even trigger low salt with too much salt content
So remember 3000ppm

If you are higher than the 3500 then drain 20% water and fill with fresh
continue this until you get to close to 3000

If low follow directions for low salt either on the test directions or bag of salt

I have had my system for this being the 4th season and have never cleaned the cells

any way, when you get the pool to around 3000 filter only for about 12 hours then turn on your generator

It should work fine

KEEP GETTING A CODE 91 LOW SALT?


Hello,
As mentioned in many of my post's, you can not just go by the reccomended amount of salt in the owners manual.
You must get salt test strips that read in #'s not colors and get your salt as close to 3000ppm as possible lower than 2800 and you will not generate enough chlorine or trigger low salt alarms
any higher than 3500ppm and you could get cloudy, or trigger high salt alarm
the water will also taste too salty when adding salt dont forget to stir up the water and filter only for at least 12 hours before trying to generate salt

Longer if you ad a lot of salt like 75 lbs or so

Code 91


91 means Low Salt. I have seen this occur if the salt level is actually too low as well as when the plates have a large amount of white crystals on them. If your plates look clean (I use a pressure washer to clean them), check the salt level using salt test strips you can get at a pool supply store.
