Intelichlor ic40 problems

[Dstockton24]

My ic40 is not working. Sometimes when I turn it on I only get a solid red salt light and sometimes I get more lights like the pic. Any ideas?

What is your version number and production date? See sticker on bottom.

What is the water temperature?

What is your actual salinity as tested by a good salt test kit like a k-1766?

D,

Welcome to TFP... A Great resource for all SWCG Questions..

If your IC40 is like mine it is almost impossible for me to get into a position to read the "sticker on the bottom".

A Pentair tech came out the other day to replace an bad temp sensor under warranty and he just stuck his cell phone under the unit and snapped a pic.

I would have spent an hour tying to get into a pretzel position and then had to use a bottle of Advil to recover...

I like his way better.

I think my sticker is gone because I don't see it. I think the unit is around 4 years old. My water temp is 72 degrees and the salt is 3500. Here is a pic of my unit this morning with only 1 light on.

The IC 40 will not calibrate or work right until the temperature of the water is 70%.

Test your water manually and make sure you have enough salt and that the water is warm enough for it to start working.

Cold water cutoff is about 52 degrees Fahrenheit. The Intellichlor does have temperature compensation. Pentair recommends that the unit not be used under 60F.

At 60F, or above, the cell should work as long as the salinity is sufficient.

I suspect that the cell control pad has gone bad. Sometimes water will get into the control pad and short it out.

To check for the sticker, loosen the unions and rotate the cell so that the bottom is easier to see. Or, just remove the cell and check the plates at the same time.
