How To Repair Intellichlor Salt Cell

cleverscreenname

I am brand new out hither. merely bought this house with an 25,000 gal in-ground puddle. The Ic-40 worked for a little bit when i first fired up the pool, at present zilch. It just sez low salt all the time, fifty-fifty though my salt is 5,900 ppm. I chosen pentair and at that place communication is to purchase a new i. Can this be repaired? Whatsoever advice would assist cheers!!

If the problem is with the jail cell, they can generally not be repaired.
Many pool stores take the ability to test whether the cell is expert or not.

What age is the IC40? They are notorious to have failed temperature sensors in the catamenia switch. Easy prepare and if not nether warranty yous tin can get aftermarket brand switches for ~$60 on Amazon. Easy to supersede.

If the unit is a new version, there is a protocol to check if the sensor is bad. It was posted on the forum so if you accept a newer cell version we can search for it.

Take care.

csn,

Hither is the examination that was referenced above... it came from JamesW who is an proficient on a ton of unlike stuff...

Pressing and property the "More than" button launches the Arrangement Status Mode. When the lights finish scrolling, the percent lights indicate hours of usage in 1,000s. For case, if the 40% calorie-free lights, that indicates iv,000 hours.

Version 3.1 on adds the ability to decide system temperature. Pressing the "More" push button after the display shows 1,000s of hours of usage, will show temperature as follows:

Lights…………….....………Temperature
No LEDs………….…..………Below 30F
40%..........................36 to 45F
forty% and 60%............46 to 55F
60%..........................56 to 65F
60% and 80%............66 to 75F
80%.........................76 to 85F
80 and 100%............86 to 95F
100%.......................96 to 99F
100% blinking……..….over 99F
All LEDs blinking……...Sensor bad

The temperature sensor is a 10k thermistor. Its resistance varies based on the temperature. The way information technology varies is known precisely. And then the box measures resistance in ohms and calculates the temperature.

If the thermistor fails in a manner that's obvious to the software, the software will ignore the thermistor and utilize 75 degrees F as the temperature.

When using 75 as the default temperature, the salinity will be miscalculated by the software for any water temperature other than 75 F.

The further the h2o temperature is from 75F, the more error there will be in the salinity adding.

If the thermistor drifts off calibration in a style that's not obvious to the software, the software will utilize the incorrect temperature and the salinity will be off depending on how far the water temperature is from what the software thinks the temperature is.

I suspect that the software is probably getting a temperature reading in the high 80s or 90s.

Ane thing you could do is to cutting the greenish and white wires. This should make the software utilize 75 F as the default temperature since information technology will lose contact with the sensor. This might brand the jail cell piece of work again.

You could measure the resistance of the sensor by putting the exam leads on the green and white wires going to the sensor. The resistance should match a 10k thermistor chart. For case.

Temperature……….Ohms
60……………………… fifteen,310
70……………………… 11,882
77…………………….. x,000 (The 10K reference betoken)
80…………………….… nine,297
ninety......................7,333

For example, if you lot measure the resistance as 7,333 ohms, the system thinks the temperature is 90F.

Even so, if the h2o is only 65 F, then the organization is going to calculate the salinity every bit much lower than actual.

Interesting, I did not consider that information technology could just be the sensor.

Thanks for all the information and assist!! My ic40 is 5 years old. Do low temp. and low table salt go manus in mitt? Mine has the low common salt trouble.

Philo

Cheers for all the data and help!! My ic40 is 5 years former. Do low temp. and low common salt go hand in paw? Mine has the depression salt problem.

I think both are controlled from the sensor. My SWG was temperamental until I replaced the sensor, and then shine sailing!

mknauss

The result of a bad temperature sensor is a depression salt indicator on the IC40. At v years former, information technology might be the cell is at the end of its life.

Can you practice the System Condition Fashion procedure Jim shows to see how many hours your jail cell has run? If higher up 6000 or so -- might be time for a new cell.

Skillful luck.

I am make new out here. just bought this house with an 25,000 gal in-ground pool. The Ic-twoscore worked for a little bit when i first fired upwards the pool, now null. Information technology just sez low common salt all the time, fifty-fifty though my salt is 5,900 ppm. I chosen pentair and there advice is to purchase a new ane. Tin can this exist repaired? Whatsoever advice would help thanks!!

five,900 ppm for common salt is VERY high. That volition put a monkey wrench in it's ability to piece of work as designed.

mknauss

5,900 ppm for salt is VERY high. That will put a monkey wrench in information technology'south ability to work as designed.

Actually it will work fine at high table salt concentrations. The issue is the high salt does go into the realm of corrosion of metal items in and near the pool when that high.

Philo

chem geeks thoughts:

"If the salt levels were very high, and so the much higher currents might cause problems elsewhere in the system if not designed for such currents. Though they are for a shorter period of fourth dimension, higher current through resistance means more heat generated and that tin lead to college temperatures, perhaps in the electronics, wires, etc. that might not exist dissipated as effectively and could crusade problems. I suspect y'all'd take to get the salt level pretty high before you see such furnishings".

"If the salt levels were very high, ...I doubtable you lot'd take to go the common salt level pretty high earlier you lot see such effects".

Richard

How was the 5900 salt level obtained? Even so, is 5900 VERY high, PRETTY high or not really that loftier?

Pretty high for the Usa, normal for the Australian SWGs I retrieve.

Bounding main is 35000, so low compared to that

csn,
Hither is the test that was referenced in a higher place... information technology came from JamesW who is an expert on a ton of dissimilar stuff...

Pressing and belongings the "More" button launches the System Status Style. When the lights finish scrolling, the percent lights point hours of usage in i,000s. For instance, if the 40% calorie-free lights, that indicates four,000 hours.

Version 3.1 on adds the power to decide system temperature. Pressing the "More" push after the display shows i,000s of hours of usage, will prove temperature as follows:

Lights…………….....………Temperature
No LEDs………….…..………Below 30F
40%..........................36 to 45F
40% and 60%............46 to 55F
60%..........................56 to 65F
threescore% and 80%............66 to 75F
lxxx%.........................76 to 85F
80 and 100%............86 to 95F
100%.......................96 to 99F
100% blinking……..….over 99F
All LEDs blinking……...Sensor bad

The temperature sensor is a 10k thermistor. Its resistance varies based on the temperature. The way it varies is known precisely. And so the box measures resistance in ohms and calculates the temperature.

Yous could mensurate the resistance of the sensor by putting the examination leads on the greenish and white wires going to the sensor. The resistance should match a 10k thermistor chart. For example.

Temperature……….Ohms
60……………………… fifteen,310
70……………………… 11,882
77…………………….. 10,000 (The 10K reference point)
80…………………….… 9,297
90......................seven,333

For example, if you mensurate the resistance every bit seven,333 ohms, the system thinks the temperature is 90F.

Yet, if the water is just 65 F, then the system is going to summate the salinity as much lower than actual.

Thanks, I followed your suggestions and I was able to find out the problem with "low salt" red calorie-free on on my ic40. Bad thermistor.
