SOURCE: I have added 40# pool salt to our Intex 52

Can you clean your sells? Give that a try ... dont over salt your pool.

If you still have a question, consult your pool supplier. They are nice people.

Hello,
First of all 91 is low salt content not too much

Are you checking your salt level with a test strip
You need to be at 3000ppm anything under 2800ppm can trigger an alarm and not produce enough chlorine.
Same thing if you are over 3600ppm
all manuals just give you an amount to start with but it is up to you to fine tune it

After adjustments you need to filter only for 24 hours before trying to generate chlorine

Do you have 3200 ppm salt in your pool? Have your pool supply place check it for you.

SOURCE: constant code 91! after only 1 week my first

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

Why do i continue to show low salt?


I do have the same problem every few days all I just discover is that I remove the cell tube and with the help of a long thin knife I clean the surface of the copper cell both in between and outsides. There is always dry salt on the surfaces and after the cleaning the sensor reading is in acceptable level so the chlorinator is working perfect without any 91 massage. To work it every day in order to avoid this happens very often and of course every time you hear the beap sound you have to repeat the scrutching and cleaning with the nife,

What is the recommended end-of-season maintenance for the chlorinating pump?


According to the Intex website, the following maintenance is required for this product:

The Intex Saltwater Pool Systems are designed to operate with a minimum amount of maintenance. It is recommended to always turn the pump on prior to turning on the Saltwater Pool System (see Owner's Manual) unless the chlorine generator is part of a combination pool and filter set, to ensure that air pockets are eliminated from the hoses, and that water is flowing through the unit. In addition, the electrolytic cell should be examined and cleaned if necessary. The frequency of cleaning will depend on the local water conditions, pool usage conditions, and length of time the Saltwater Pool System is operated each day. (See Owner's Manual.)

The Intex Saltwater Pool Systems contain several features that minimize maintenance requirements:

1.) An automatic self-cleaning cycle: The Saltwater Pool System automatically undergoes a self-cleaning cycle to maximize the operating length of the electrolytic cell.

2.) Safety diagnostics: the Saltwater Pool System will alert the operator to three conditions that could result in poor operation: Low water flow through the unit, Low Salt level in the pool water, High salt level in the pool water. If any of these conditions exist, the system will sound a buzzer, and flash a digital code on the control panel (Model 8110) or a Red LED will light up. (Model 6110).If the condition is not addressed, the system will automatically shut itself off to prevent damage to the unit.

Have an intex 16 x48" salt water pool generator


I checked the Intex web site and here is what they said:

There are several things you may need to check and do:

- Test the salt level first with Test Kit, and add salt as needed.
- Remove the electrolytic cell for inspection and clean it if necessary.
- If code 91 still appears despite the above steps, there might be a possible electrolytic cell
failure. Please contact Intex Service Center, and replace the cell if needed.

NOTE: Always turn the power off and disconnect power cord before cleaning and servicing.

I hope this helps.

I have added salt due to constant low salt warning. I have been brushing and running pump. It appears to be on a 6 hr cycle as 06 shows up when turned on. It also goes into sleep mode. Test strips show...


Way too high on the salt.. about 5000 to 7000 ppm. You should be around 2000 to 3000 ppm or 5.6 to 6.6... I had the same issue with my system and it's always the cell..Look inside the cell and if you can see white stuff inside, it needs to to be cleaned... The manual states to soak with vinegar for 6hrs.. I soak mine for 24, flush and soak again for 6hrs and flush again.. Comes our clean.. and the low salt alarm goes away until the next time the cell gets dirty with the white buildup... You can add an additive made by hth called "Cell Saver"..Prolongs the cleaning cycle... After you clean the cell and your filter, change your chlorinator cycle to 10 hrs with your pump to run 11 to12 until the pool clears and then lower to maintain the proper chlorine level.. Good luck and hopes this works for you.....

Getting a code 91 LOW SALT. We have had our pool since June. Took a sample to the local pool shop for them to diagnose and my salt was at 4200ppm. It is still triggering low salt....any suggestions?


Usally if the salt level is above 2000 ppm, it's the electrolytic cell. Did you look inside and verified it did not have any white flaky buildup on the plates??? Do the following if you haven't already and see if the low salt alarm goes away..

  1. Remove the cell unit and cap one end...
  2. Fill the unit with white vinegar and let soak for 24 hrs...
  3. Flush with pressure nozzle until clean.. ( If you can still see some white stuff on the cell plates, soak for and additional 6hrs and flush again)
  4. Re- assemble and set your cycle according to your chlorine level...
Hope this works for you!!!

When i change the pump filter let run for a while code 92 sets


2 reasons for this code...
1st... High salt level... You must check and should be between 2500 to 3000 PPM.. If higher, drain some water and fill with fresh water and re-check..
2nd... If salt level is okay, your electrolytic cell may have calcium buildup and must be cleaned and flushed.. Cap one end of the cell and fill with vinegar and soak for 6hrs+. Flush with water pressure until blades inside are clean and free of the "White Flaky" stuff...
Hope this helps you???
Good luck...

How to stop it frfom beeping/flashing 91 low salt.


1st... Check electrolytic cell and clean with vinegar...If white scalley stuff inside, cap one end and soak for 6 to 12 hrs and rinse until clean
2nd...check salt level, see manual for PPM, if low, add salt.. If you have a big pool 12000 to 15000 gallons, you will have to add up to 100 lbs of salt..

4th... Set you cycle and should be fine
