Okay - it's been a while but... I sent an email to Pentair hoping they would be able to help, and lo and behold, they made arrangements to have the cell replaced! They guy came this morning and put in a new/replacement cell, and the pool is back in operation! Pool guy asked who cleaned the...

I struggled to find the warranty information but eventually was able to locate it. Says two years. Man that would be fantastic!

Unfortunately, the replacement switch did not resolve the issue. :( Cell produces chlorine for a short amount of time after startup, cycling on and off, and then it goes into blink mode. On the plus side, replacing the water temperature probe did resolve that issue. Water temp shows 69 degrees...

Hi Deb - I very much appreciate the offer. I will keep it in mind. I'm hoping the new flow switch fixes things.

I do not have a heater (other than living in Arizona). ;) So, the IC40 has its own sensor, and the Easytouch has two sensors, one for water, one for air, yes? Then the temp. sensor on the flow switch is used internally by the IC40 and is not reported to the EasyTouch? Is that correct? And the...

Thank you. I have just ordered a replacement flow switch. So, what is the temperature sensor between the pump and filter? Air temp?

Was getting the pool ready for swimming and all seemed okay, but yesterday I noticed no bubbles coming from the jets, and the Cell LED was flashing green indicating "Check Cell". I have not checked the chemistry yet, but the water was okay last time I did check (a month ago?) My IC40 was bought...

Hi. I put in what I thought would be ballpark, knowing the chlorine level would quickly drop. And it did, as expected, giving me a starting overnight CLT. Today, I am monitoring and adding chlorine as needed to maintain 24ppm. After adding 2 gals this morning, I tested moments ago - 23ppm. The...

Just a status update. I added 8 gallons of 10% liquid chlorine to my running pool around 8AM with the pumps running full tilt. I waited a couple of hours and checked the chlorine level - 32ppm, overshot. By around 6PM, chlorine level had dropped to 24ppm. Water was murky but less green. By...

No - it has a drain valve I attach a hose to. Water was too murky to see anything, so I scratched the idea. We had rain predicted for yesterday (didn't happen) and more for today. On the plus side, I now have 24 gallons of liquid chlorine ready to get started.

Exactly my thinking!

Well, since the water level is high (covering the skimmer intake), and there is algae coating the bottom, I thought about using a vacuum brush to vacuum out at least some of the surface algae. Might be useless, but it will make me feel better. ;)

And the calcium and/or hardness? Is that any concern at this point? Thanks!

Okay, here are the results: Daily tests - Chlorine - 0 pH - 7.2 Weekly tests R-0870 no or extremely light pink R-0871 maybe 2 drops so 1ppm R-0003 5 drops made it pink R-0871 2 drops made it clear so 1ppm Calcium test 625ppm Total alkalinity test = 130 CYA - 60

So, don't drain anything, clean anything, leave it as is and run tests and post results? I can do that. ;)

So, TF-100 test kit arrived this afternoon. Water is somewhat murky. Algae on bottom and sides of pool. Just had heavy rain last night. Might get more tonight. As a result, pool is filled over the skimmer intake. With that said, where should I start? As is or what?

For the longest time, the cell was easy to maintain - it had a little scale most times, easily cleaned with a weak solution. Whatever happened recently, the "Flow" sensor malfunctioned (and it was physically damaged - the plastic stalk was split). I replaced that, and when I went to check the...

Says 3300ppm and also CLEAN CELL!!! I don't know the actual salinity at this precise moment. Kinda hesitant to get it tested. In the past, Leslie's tested it @3400.

The IC40 "Cell" LED is flashing. That's the only LED that's not normal. Everything else shows as okay. I just ordered a TF100 from Pool Supply World. Added another 4 3" chlorine pucks to skimmer. Pool water is clear but not sparkling/crystal clear. Surface algae on bottom, some on sides...

Hi guys, and thank you for the quick replies. Do I acid wash? Yes, with 3:1 or 4:1 solution depending on how it looks. I also used the descale stuff that's supposed to prevent build-up and, quite frankly, it worked well enough I had to clean the cell only occasionally. What % output? 100%...

Okay, so my 3-year-old IC40 is now blinking, and I'm a bit annoyed as this is the 4th cell we've had in 12 years (3 year avg life) for a 12000gal pool. A new cell costs another $500, but given the frustration I've had over the years with these things, I'm considering changing over to an in-line...

Thanks very much. I'll get on it.

Hello! The first thing I tried was Algae Guard. https://www.walmart.com/ip/HTH-Super-Algae-Guard-for-Swimming-Pools-1-qt/590383746 I then tried superchlorinating the pool using HDX 10% sodium hyperchlorite...

Thanks very much! I am pretty sure I'm having an algae bloom. I tried my "usual" combo of shock and algaecide to no avail. I'll have a go at SLAM.

I noticed since we installed a VSP (two years ago), our Intellichor IC40 output has been kinda milky looking. I hadn't thought much about it while the water was clear figuring it was because of running the pump at lower rpm (e.g. 1400) making it visible. But a few weeks ago, the flow sensor...

The other morning I woke up at dawn and noticed my pool lights were on. I went to investigate and saw the IC40 chlorinator was lit like Christmas, but the pool pump was not on (it has its own timer). I *thought* maybe the light schedule had gotten mucked up, so later in the day I deleted the...

Thanks Jim. I saw the four small relays on the back of my board and thought that's what made it a 4. When I saw the same on the 8 I was scratching my head.

I was curious about my panel, and I'm even more curious now. I found an old thread (Upgrade EasyTouch 4 to 8 - Circuit Board replacement only?) where someone talked about upgrading the motherboard from EZ4 (520659) to EZ8 (520657). I looked on Ebay and found a few 520657's for quite a bit of...

LOL - I had not even noticed that before - indeed it is a circuit breaker with a "reset" button for the SWCG. There's also an Intellichlor status LED slightly to the left. Aux1 is the lights, and Aux2 and Aux3 are unused.
