OK! You were right! (Sounds like a conversation with my wife.) :oops: Two thumbs up to Pentair warranty service department.:goodjob::goodjob:

The end to the story: After an initial slow response, Pentair stepped up and did the right thing. They finally got back to me (via email) and dispatched a warranty service tech. He showed up this morning. He quickly determined that the IC40 circuitry had "died" and he immediately replaced the...

Yes, I added a bit of salt when this began. Raised my level from 3200 to 3400ppm. I know the IC40's salinity calculation reads about 4-500ppm low. I finally got a response from Pentair yesterday AM. They're asking for receipts, etc.. They may replace it under warranty. Fingers crossed! BTW, I...

mknauss, appreciate the info on the IC40 salinity generation values. However, my pool salt level is 3400ppm as measured 3 days ago via the Taylor K-1766 kit. Something is still wonky in my SWG. I did notice that the start up sequence seems to take a bit longer than the "normal" 2 minute cycle...

Dirk, appreciate the info on temp sensors. However, the SWG weirdness continues! I replaced the flow sensor with an aftermarket brand. It worked fine for a day. Now the red "Low Salt" LED is back on! The SWG appears to be producing chlorine (bubbles in return water and maintaining FC level) but...

A little techie info for those who care: I discovered that the thermistor built into the flow switch is a negative temperature coefficient (NTC) type. Meaning as the temp rises, the resistance drops. Evidently, the Pentair thermistor is set for 10 kOhms at 77º F. I took the bad flow sensor out...

The saga continues.... Today, I went out to do my daily pool check. I noticed there were NO lights illuminated on the IC-40. I began troubleshooting and discovered the IC-40 transformer fuse had blown. I replaced that fuse, reenergized the panel, and restarted my pool equipment . The IC-40 did...

I did the install myself. The Pentair website doesn't require "professional" install for 2 year warranty. You get an extra year with pro install. I'll try calling but being a holiday weekend with COVID, etc, etc, etc., not confident about reaching anyone. Thanks for the input!

Thanks. I'll order new aftermarket flow switch today. Is there any way to test the thermistor, e.g., with a multimeter?

Thanks for the rapid response! I purchased the IC40 in late August 2018 off Amazon. According to Pentair website, their SWGs have a 2 year warranty when purchased alone. Looks like I'm out of luck for a warranty repair. Guess it's time to try a new flow switch/thermistor. Any issues with...

My Pentair IC40 SWG suddenly started to show the red "Low Salt" warning light two days ago. I checked my salt levels via the Taylor K-1766 kit. Two tests came back with 3400 ppm, so I know the salt level is not low. I checked the plates on the SWG and they did have a small amount of scale on...

When I installed my SWG about 6 years ago, I had a similar problem. The pH was climbing almost daily due to the carbonation effect in the SWG. I solved the problem by installing a Pentair IntellipH acid injecting system. My pH is now extremely stable (7.4-7.6) because a small amount of MA is...

Richard is absolutely correct. The lack of "sparkle" is due to high pH and low FC. My pool is currently at 750 CH and I have to get to 7.4 pH with a TA of 60 to keep the "sparkle". Since I'm using an SWG, I put in an IntellipH acid injector in 2015 to keep the pH under control when I cannot be...

I've used it with good success on PVC and other plastics. The surface must be clean of dirt and other contaminants (grease, etc.) but it seems to adhere very well and hold its color out here in the hot desert sun.
