Intex 8110 Chlorine Generator Fix

After reading the responses and experiencing the exact same problems after only a month and a half of use, I decided to dig deeper into the low salt problem everyone is experiencing. I pulled the entire unit out so I could get a better look at the components. Everybody seems to be focusing on the copper electrode which is the removable part that has two large copper bars. I discovered that isn't the problem at all. There are three thin metal plates about 5 inches long mounted a few millimeters from each other permanently inside the plastic cylinder. I also noticed a build up in between these plates and completely across the energizing terminals. I followed the troubleshooting guide previously and filled the cylinder with vinegar for about an hour. This time I did it again with the unit up on a workbench so I could see everything better. The first problem I noticed is that when I filled it up, there were air bubbles so the vinegar was not reaching some crucial places. I stood the unit on end (the flow sensor end) until the air bubbles worked their way to the top. Then I let the bubbles out and topped it off with vinegar. I could see the vinegar going to work as tiny gas bubbles were being released. The second problem I noticed was that it took a lot longer than an hour to remove all the build up that was shorting out the plates. About four hours later, the bubbles stopped and the plates and terminals were clean. I flushed the system out with fresh water, reinstalled it and everything is working fine. A couple notes, don't screw the electrode flange back on because the gas bubbles need someplace to go. Also, I jacked the electrode end of the cylinder up about 45 degrees to keep everything crucial submerged in vinegar. Make sure and use white distilled vinegar. Good luck to all of you. I hope this solves your problem.

I,ve been reading the posts, I too have a code 91 flashing alot,driving me nuts as the water is very salty now! The transtormer does feel quite hot. Where would I order a new one?? It sometimes works better if I do 1 hour at a time, not that handy to do that though, any suggestions??

Hi all, new to this forum and would just like to agree with EkLudwig1's post, I also discoverd the problem to be the salt build up between the plates and around the terminals, I use kettle descaler to soak mine(works much better than vinegar) and also clean between the plates with a long thin knife this seems to solve the problem for a month or so not a permant fix but at least it stops the dreaded '91' code for a while.

Code 90 low flow error. Finally found what the problem was on my 8110. Would turn on system and approx 30 seconds later 90 error code would appear. Traced it to the connection on the flow switch connector. Took some small needle nose pliers and carefully squeezed the female metal connections inside the rubber cord connector on the cable side so they would make a tighter fit. I was able to get the pliers in between the rubber socket and the metal crimp connector to avoid possible damage to the rubber seal. So far so good. Hope this helps someone.

8110 temperature wrote:I think i may have a good explanation to the 91 or 92 codes. The 8110 measures the salt concentration through the conductivity of the salted water. And obviously, the conductivity of salted water - as any other solution or solid - is linked to the temperature of the solution or the material. As a result, the same salted water will feature a lower conductivity at 15C than at 25C. For reference, a salted water is twice more conductive at 37C than at 5C!

I have not seen anything about this from Intex or in any other place. your thoughts?

I have to agree with this - ours only pulls the 91 error when the weather turns colder - Nov thru Mar or so.

What if your resistors aren't marked VR1, VR2 or VR3? Mine seem to be marked something different.

There seem to be many ideas about how to re-calibrate the machine or by pass this and that on the circuit board. But the simplest solution is the obvious one. Vinegar does descale hard water deposits, but I was using vinegar and still get low salt codes. My salt is at 35000ppm according to the local pool store. Living in South Central Texas and dealing with hard water all my life I went back to the tired and true hard water cleaner that my parents relied on..... Sanivac. This is a purple colored solution that eats up hard water deposits. I put the end cap on the unit and filled the tube with 1/2 water and 1/2 Sanivac. I left it overnight. This morning I have shiny clean plates and no hard water deposits. I'm going to work harder at maintaining better ph this season and see if the vinegar will serve to maintain the system. I don't think I would use the sanivac all the time. IT is a strong chemical and can ruin your clothes and kill the grass so I did this work on my patio and drained it in the sing. I can't help but wonder just how efficient the machines that have been re-calibrated not to throw codes are working.

Believe me: Water temparture to low! It has to be +-20° otherwise code 91 is still occuring.

Please help! I have the 8230 model and keep getting the 91 code. Salt levels are fine. The titanium plates are clean. I have reversed the plug to reverse the polarisation. I have opened up the whole system and all seems fine. I've been told not to try the RV1,2,3,4 thing as this reduces the actual amount of chlorine produced. I dont have an electrical test kit so cant test all electrics working fine until I buy one. When I turn the system on it actually does produce chlorine for a couple of minutes as I've tested the water flowing into the pool, but after a couple of minutes the alarm sounds and chlorine production stops. I am getting desperate as I live in Cyprus and we are not allowed to fill our pools up ourself. It costs me 200 euros to fill it and Im now in danger of my water going off to the point of no return. Any other suggestions welcome, but I'm not an electrical genius. Does anybody know if until I get it working if I can just add my own chlorine? I've got visitors coming out on 25 Apr and they will want to use the pool.

I purchased my chlorine piece of junk generator last year and had issues with it like crazy and was glad the season was over. This year hoping for a new outcome everything was fine TILL NOW. It will click into working mode with the green light on but no chlorine is being generated and after 1 minute the service light comes. All my chemicals are exactly where they need to be,flow switch has been tested and works great. Cleaned out the electro cells overnight and crystal clear. So I am lost what to do and did I also mention when I purchased this item I lost the receipt two days later GO FIGURE. Any clues or rigg up I can do just to make chlorine would e great.
