ic40

My IC40 is erratic. Actual flow in the pool is excellent. Filter is clean. New flow switch added. Fins in the IC40 are open. Unit blinks on salt yet salt measures 3800 ppm. Flow light will not turn green and no chlorine is being generated. The unit is five years old. (Originally I had three...

Howdy all! I've posted previously about replacing my compool control with the Nixie Nodejs Stand Alone running on a Raspberrypi, as well as where to place my chlorine generator. I'm happy to say that I've completed the Nixie installation and could not be more pleased... I wish I would have...

Just installed a Pentair Intelliph system with my Easytouch and IC40 SWG. Pool automation is working fine but when I powered up the Intelliph system for the first time, it said no dispensing due to spa mode. I switched the system to spa and it started dispensing so somehow intelliph sees my...

Red flow light on ic40 pentair intelliclor bought a little over 2 years old. Cut the flow sensor wire and it was 3 wire black, red, white) Ordered replacement part on Amazon and it has 4 wires (black, white, red, and green) How do I connect these to get this to work? Seeing various information...

So, I have been lurking here for a while and just completed my DIY SWCG install last weekend, Just wanted you guys to check my work, inspired by threads from @MyAZPool. Pentair Intellicenter i5p installed with ic40 SWCG. I wired the SWCG on it's own relay but tied to the pump relay so it will...

Hi all, It's been a while. My IC40 seems to have died (not producing chlorine). I tested by running her overnight and saw no increase in FC. This would be my 8th season with her so I've gotten my monies worth from her. Just want to check for suggestions before I toss her. The only error/alert...

Been a pool owner since 2019. The pool is fairly old, and I think the previous homeowners knew everything was about to die (not just the pool) and decided to sell. At opening 2020, IC40 worked fine at first, but then died (no lights). After some research, I determined it was probably beyond...

Hello everyone. I have a pool I had built close to 5 years ago and a IC40 was put in. I havent had any trouble out of it until this year when I went to open my pool it shows a red flow light and the salt level is blinking between good and low. My assumption is the salt level reading isn't...

I know there's an older threat, but it suggested I create a new one, so here we go. The COLD WATER light in currently on my Pentair Intellichlor IC40. I live in Houston, TX, so I know the water is not cold in mid April. I tried following the steps in the previous post, pressing the MORE...

Hey all, Ok I got one for you.... My pool guy is stumped, his Pentair reps are stumped, lets see if any of you have come across this. My Pentair IC40 generator has had the low salt light on all season since opening up. So initially I thought, ok and added a bag of salt which took salt too...

I am having an ongoing issue with the spring steel on the flow switch failing. I’m looking for some advice on what the issue could be. Here’s what’s happened thus far: - IC40 was installed - After about 4 weeks the sensor failed. - I ordered a new one on Amazon. Pentair factory replacement. - I...

Hi All, I recently moved to Florida into a house that has a saltwater pool. This is my first pool ever, so I'm still learning the ropes. Everything went smoothly for the first 2 weeks, but the kids complained that the pool was too cold, so we had a pool heater put in. About a week or so...

Hi everyone, I just finished installing a new flow switch on my Pentair Intellichlor IC40 because the flow light was off and I noticed the flow switch was cracked and my pool was starting to turn green. After installing the new flow switch, the Flow light is now red and the high salt and low...

I‘ve got a 3 or 4 year old IC 40. Cell light is green, flow light is green. My salt is good (about 3600 - tested by me). But neither of the salt lights are on. Very puzzling. I don’t need the thing to tell me how my salt is - I can test it just fine, but I do need it to make chlorine...

As I readied my pool for the season, I added the proper amount of salt to reach 3600 PPM. Let me start by saying my IC40 was manufactured in 1/18. With all lights green, I noticed that the low salt light on my IC40 never turned green and was red and was never producing chlorine in the pool. I...

It's been more than 60 days since I last responded to my original post, so in accordance with Forum rules I am starting a new follow up thread. Here's the original post: https://www.troublefreepool.com/threads/backwash-valve-exploded.197116/#post-1738460 Essentially, my plumbing blew out around...

I have the IC40 Chlorinator and Intellichlor Circuit Board PN 520723. I lost power to IC40 and check the board. The black wire obviously was heated and on the circuit board I also see the black on D8 and D7 has been cracked and shows sign of heat. I have no issue replacing the IC40 and the...

I've searched and found that reagents are good for at least a year, probably longer (most threads related to typical chemistry - FC, Ph, etc). Does this apply to the salt test reagents from the Taylor K-1766? My R-0718 reagent shows an expiration of 08/2019; the R0630 expires 4/2020. We had a...

The trouble started with a red flow switch light on my Intellichlor IC-40 even when there was good flow (a problem noted by others on this board). I tried bending the flow switch stalk and then the light was always green, even when the pump was off. This worked to produce chlorine, but I didn't...
