Hello Fellow Code 91 people. I had this problem as well. Turns out I have a blown cell Fuse. F2 and F3 are fuses for the DC cell. These seem to be rated at 10Amp as far as I can tell. I Installed 8 amp resetable fuses and everything seems to be running fine. I am running 6.2 amps 3200 ppm salt and the water is 68F this is the second season using the chlorintator. For those who find the reseting the time a nuisance with power failures I run the system on a 500VA UPS. Seems to work great. Though on hiccup is that is the storm hits while chlorinating generally the unit shuts the UPS down fairly quick (10 mins or so).

Hopefully this helps

The problem I have is I can set timer and all seems to be well ....but the green light never comes on even though the unit counts down as if its working! It does not produce anything! and no alarm codes at all? The salt in the pool is perfect as I have tested it. I realy have no Idea why its not working.

Try cleaning the cell plates whit muriatic acid diluted with free chlorine level wouldn't rise no matter how long i would set the chlorinator. it worked for me wile pouring the acid on the plates I could hear it fizz like a cola drink I repeated until it stopped fizzing.

I have the Intex 8110 which has been running for 4 years now. Last year, I started getting the dreaded Code 91 alarm. After checking my salt level (which was fine), I tried the resistor adjustment mentioned previously. This seemed to work fine last year, but the alarm came back again this spring and no amount of resistor adjustment would work. So while taking off the cell to clean it with CLR, I noticed that the two pin contacts had more rust than a 71 Civic! It looks like there is a pinhole leak around the pins and the salt water gets in there and corrodes them. Anyhow, I cleaned the pins and the plates (which were pretty clean anyhow), and the whole thing came back to life and is working perfectly now. Hope this helps someone! :D

I have owned 3 intex model 8110 units. (they do not deserve to be capitalized) :thumbdown:
The first was purchased in 2006. It was replaced under warranty. :thumbup: It's replacement had a leak around the cell post (and is not under warranty) :thumbdown: The leak caused rust to develop in the connector. After cleaning the connector and putting dielectric grease on the contacts, the unit worked for a short time, but code 91 returned. After reviewing ALL the previous posts, here are my conclusions on the 91 code fix, given in order of importance and ease.

1. Start by reading the manual and following the cleaning instructions for the cell. Clean the cell in kitchen grade vinegar for 2-3 hours and flush with a water hose afterwards. Do not use any metal objects to clean the electrodes. (I did this on a "clean" looking cell, and got out deposits that were not visible)

2. Reverse the plug on the cell (put the plug on upside down)

3. Open the case and adjust the resistors

4. Rewire the unit

Steps 1 and 2 have worked for now, so I have not bothered to go onto 3 or 4. :D

God bless America, this site and the wonderful people with their answers. My husband suggested i search for a fix and this is where i wound up. i did the rv1 1/4 turn and "bingo!" my saltwater system is golden. i have to admit it took me almost 10 min to find the rv1,2,3 things. they are right in the lower middle of the circuit board behind stuff so ...i guess i'm a little slow on the uptake. none the less, thanks for saving me the cost of a replacement unit. this is my 3rd or 4th summer with the intex saltwater unit and i couldn't be more thrilled. 2 of my neighbors have them now per my urging. they also are thrilled. other than this years startup, i have not had 1 single problem with my unit and it has saved us so much $ in chemical and our skin from the alternative severe clorine system. God bless you all.

Xlav8r wrote:Hey , the "CODE 91" fix was said a while back regarding resistors. pull off cover carefully, both the flow sensor and cell power cables exit the case making lifting the plastic case difficult but manageable. look for three adjustable resisters, one above the other. They are marked (or mine was) VR1, VR2,and VR3 on the circuit board. they were black and about the diameter of a pencil eraser with a small Philips (+) adjustable head. The head was locked with glue? but it can be scraped off. The original suggestion said to turn the VR1 resister a quarter turn CCW. This did not work for me but I added an additional quarter turn CCW (now half a turn CCW) and it is back working as it did originally. I will keep an eye on my salt content to keep at 3000ppm as suggested in manual.

NOTE: I have now taken it apart and scrapped off the glue - but seems that the screw is plastic and I have destroyed the screw in an attempt to turn it. Not good - I'm attempting to get a 1/4 turn on a destroyed plastic half glued screw... aaaahhhhh
