IC40 salt reading 9,900

[Sk8Surfr]

4 years old. Shows 60% life used. Reading 9,900 PPM. (when it's really 3,000). I read the flow switch is where the salt reading comes from and I might be able to just replace that? Am I reading this correctly?

How are you measuring salt? (You should be using a K-1766.)

pool store - and it matched intellicenter output last week. now its stuck on 9,900

Sk8,

The flow switch assembly does NOT measure the salt level..

It does have a water temp thermistor that tells the cell what the water temp is.. The cell than calculate the salt level based on current flow through the plates.

Replacing the flow switch often fixes the problem when the thermistor is bad and the salt reading is not correct.

There are two kinds of flow switches.. 3-wire and 4-wire... If your cell has a 3-wire cable between the cell and the flow switch, then you MUST use a 3-wire replacement.

Thanks,

Jim R.

It seems like it's not producing chlorine either... even though the green lights are on. Ran the system at 100% all night - less that 1 ppm of chlorine in the pool this morning. And if i take a reading at the return (which should have chlorinated water from the salt) - its the same reading. Just tossed some shock in...

The other weird thing - I have lost 'super chlorinate' feature on the intellicenter app - I can go to 100% output. but I no longer have the superchlorinate option

My green cell light is solid - but even filling a water bottle direct at the pool return I show no chlorine being produced.

This thing is getting on my nerves - NOW the intellicenter is saying my water temp is 103... its like 83....

I was trying to do the long hold on 'more' on the salt cell this morning to see the temp reading - I could not get it to display any lights like the youtube video I found. I also held down the less button... I couldn't have changed the intellicenter board from reading the thermometer in the inlet pipe to the salt system could I?

And today - 15 degrees is the water temp!

 

[Sk8Surfr]

Changed the flow sensor - still showing 9,900

 

[pjt]

still showing 9,900

Did you get/borrow a K-1766 yet?

 

[Sk8Surfr]

No, I tested at the pool store.

I think either your SWG (1) is bad and needs to be replaced, (2) control board is bad and needs to be replaced, or (3) your cell is depleted and SWG needs replacement. I had a similar thread about 2 weeks ago. Mine was reading 7500 salt level on ET and it got all the way up to 9500 (real salt level was 3,000 verified via Taylor test and pool store). Also, “high salt” was blinking on IC40. I replaced flow switch (didn’t help). Then I replaced the SWG with a brand new IC40. I was barely holding 1ppm FC before, now I’m at a steady 6ppm and the only thing I’ve added is salt (all of my other chemistry is near perfectly balanced). I haven’t shocked the pool since then and FC is holding and then some. I’m running SWG at 35% (8 hours per day), but dialing down every few days until FC drops to 5ppm (my desired FC level, but to each their own) and I’m being patient to find that perfect percentage of FC output.

Intellichlor IC40 SWG Falsely Reporting 7500 ppm salt level (true level is 3,000ppm), not outputting Chlorine, and High Salt light is flashing.

I have a Pentair IC40 SWG (8400 gallon pool) and the SWG is 8 years old (only 40% of cell used per diagnostic). The salt reading on easytouch is 7500 PPM. but I did my own test (3,100 ppm) and 3 tests from Leslie’s and all 3 were 3,000 PPM within a 5 day range. For good measure I replaced the...
