I had the ICM on my Pentair Master temp 400HD fail last December. I replaced it for $180. It just failed again today. The system is 8-10yrs old. Not positive. New to me last October. Anyone know why this could keep failing? What should I check? Replacing it every 10 months for $180 seems...

And I’m an idiot. When i was troubleshooting no chlorination a month ago, I unplugged the intelichem panel. Could that be the issue? :LOL:

I don’t know the age, but over 5 years I believe. The light is actually at 40% I think. And the screen logic app on my phone is set to 5%. When I change the output on my phone, the lights on the IC20 don’t change.

I have an IC 20 and screen logic. The IC 20 has the 20% light on but the screen logic is set to 5%. I assume the IC20 is controlling because my chlorine level is slowly creeping up despite daily swimming and some organic matter in the pool. But logically it seems like the screen logic, if set...

It’s a leaky Ck valve. Thanks for the trouble shooting tips! It’s slow enough that I couldn’t really tell the pool level was increasing. When the spa level got low (a couple inches loss) I turned on the waterfall to fill it up from the pool and then checked the pool auto top off. It didn’t top...

I calculated based on it dropping about 1cm over that time. It’s 6’ x 6’. Ok, I’ll try letting it get to full equilibrium. Our winds have been 5-10mph intermittently the last few days. Could the Ck valve be slowly leaking in to the main pool system, so the pool is slightly increasing on...

Turned off spa heater. After 36hrs with top on, I lost about 8 gallons. The spa temp is still 80 degrees and ambient temp in the 50s. I do see steam coming off the top of the cover (it’s raining). I suppose it’s possible 8 gallons is evaporating out of the small gap for the waterfall?

Thanks! Great suggestion on letting it get to ambient. I have only lived here for 7 months. I did not notice anything unusual until this last week when I was out of town. Came back and it was 6-8” below the top. My wife and kids didn’t use it while I was away. Previously I used it regularly...

I have a 13000g plaster pool with a connected 800g hottub. The hottub is above the pool with a waterfall. I’ve noticed the hottub water level dropping more than seams reasonable due to evaporation. The tub has a cover, but it’s not totally covered due to the waterfall part. The cover has a...

Reset the pump again and it’s working! Thanks for the help everyone.

Apparently there are two ScreenLogic apps: ScreenLogic and ScreenLogic Config. I read that link previously and it appeared to be referencing the ScreenLogic app and a configuration menu within that app. I found and installed the other app. It shows IntelliChem is disabled. IC20 still behaves...

I have an EasyTouch system. Hopefully all my details are in my signature. I have an IntelliChem and IC20. I would like to disable IntelliChem for good and control my IC20 manually. I’ve read the posts on how to disassociate but they all discuss IntelliCenter2, which I don’t have. I have at...

Thank you for the suggestion and link! Wow, what a finicky and sensitive system always on the brink.... Depending on ORP is interesting... I'm sure its much different in the pool industry because we want to kill everything, but ORP is still an extraordinarily complex process. For anyone...

Thanks. Done. I thought that info was contained within the top box with my username and “intellchlor” was the whole intellichem sysyem. Now I know those systems are separate. :oops:

Yes sorry! New to this and actually assumed the pentair SWG & intellichem were are one system that came as a package.

My PH jar did crack about 6 weeks ago, so I had to shut the valves to the ph probe. Back then you may have mentioned that I need to change something when the PH is offline. Could that be affecting the salt cell?

When I hold down the more button for a couple seconds the lights cycle and then the cell light goes on for a few seconds. Then it goes off. I have it set to 100% output and only the salt and flow lights are on. I just cleaned the cell yesterday too.

My IC-20 stopped chlorinating within the last couple weeks. When I hold down the right arrow button all the lights do some sort of cycle but it doesn’t display the hours of usage. During run time, the salt and flow lights are on, but not the cell and not the sanitation lights. I’m not sure...

This could definitely be on the right track. I’ll investigate there. Since I moved in last fall, I haven’t used the sprinklers and don’t know all the zones and lines yet.

I had some sprinkler work done in November. I suppose they could have accidentally capped something. But it’s definitely lost a few hundred gallons to evaporation in the last 4 months….

That’s what I’m thinking but I can’t find it for the life of me. My kids are going young and capable of turning something but not capable of telling me if they did. 😂

I’ve owned my pool for 6 months or so. It has an auto top off that has worked until now. I’m not aware of any shutoff valve for it and I’ve searched the perimeter of the house and haven’t found anything. I’ve been using the pool all winter and it’s definitely evaporated a lot. I have no...

My system has an IC-20 and an inline 320. I moved in 6 months ago and haven’t touched the 320. Didn’t even know it existed until today. I don’t even know if the valve is open to the 320 or closed. (I haven’t been back down to look) Is there any benefit to having a 320 inline with a SWG...

Thank you so much. It’s been very helpful. I like having a full understanding of all the electric in my house. Circuits for the home seem much more simple. On a nice weekend I’ll probably have my non colorblind wife help me label everything. :)

Both of those lines that go to the vent to under the house to the other side. They both go to this junction box. Which has a line going to the pool cover switch. Quite the mess of twist on connectors. Is this typical?

Thanks for pointing that out! The only two items protected are the lights and the pool cover. I assume current code requires all pumps that come in contact with the water to be protected? I’ve seen my share of pumps short out and energize the water in the saltwater aquarium world.
