"NOT pool in signature"
Good morning all, one of my winter pools having cell issues. Just to note this is a 4 year old gunnite 35k all pentair equipment, vsp, ETI 400 heater, large cartridge filter with the EasyTouch screenlogic setup. Took over this pool in July '22, chemistry was not existent at the time and the ic60 was calcified like a brick so didn't waste any time and replaced. This pool runs 24/7/365 so the cell has 2.5 years on it. In August I noticed a chlorine issue, inspected the cell and to my dismay the cell was calcified, I cleaned (first time) it with the typical MA ratio and back in service it went. All was good till last week I noticed the "cell" light blinking but didn't have the time to take things apart chlorine tested lower then the norm but didn'tmake much of it.. Also to note the pool gets vacuumed weekly with my "Riptide" and there's lots of calcium flakes in the water, filter bag gets pretty heavy at times. Pool uses a good amount of MA weekly to keep PH at bay. This pool always had high CH, not sure why and can't remember if I've tested the sink tap on this one so I'll put that in my scheduled to do.... I see I can manipulate a lower CSI by having the CYA elevated so going forward......
THIS:
Not educated enough on the ic60 so I need guidance on the pecking order to diagnose hoping I can save it. The screenlogic has an alert " chlorinator communications lost" . Can someone give me the nitty-gritty on diagnosing this problem and get it sorted out. Thanks in advance, Allan.Screenshot_20250210_085718.jpg

The high TA is contributing to the cell scaling. Lowering the TA to around 60 should help prevent scaling in the cell. Adding 50 ppm of borates to the pool can also help reduce the pH rise in the cell that causes the scaling.


" chlorinator communications lost" Is an RS-485 problem in the IntelliChlor or EasyTouch. It could be a board or chip problem or a wiring conflict. Depends what other RS-485 devices are connected and how it is wired.

Is the IntelliChlor surge card in the Power Center or EasyTouch?

Nothing has changed or done recently, this happened on its own.

In the EasyTouch panel
 
Disconnect all of the other RS-485 devices and only connect the IntelliChlor and see if it works.
 
Thanks but what would that then indicate.
It indicates if other devices on the RS-485 bus are interfering with the communication.

If it works with only the IntelliChlor connected then another device is causing the problem.

If it does not work then the problem is with the IntelliChlor surge card or its connection to the EasyTouch board.
 
Ok, I seemed to get off easy on this one, I followed the wire back from the cell to be sure it wasn't chewed through somewhere from a rodent and when I wiggled the wire before the cell connection under the box I saw the led's flicker. I shut down the system then unplugged it figuring I may find a corroded pin or two but all looked OK except one pin seemed to have pulled out a drop making it slightly taller then the other three, I pushed it back and then connected the cell back in and all is working. Now I need to figure how to solve the "cell led" which is still flashing. Screenshot_20250210_143748.jpg

What % does the cell typically run at?

Cell LED blinking is a sign the cell is bad and needs replacement.

Running 2.5 years 24/7/365 will consume trhe cells 10,000 hours of generation with the % 30 or more.
 
I doubt the cell is clean with all the calcification going on so I'll open the cell but need to find the cleaning stand so I can get it all done at once. Checked the hours and got 2 leds which makes it still quite young to drop dead.
 
2.5 years is 21,000 hours.

20% - 30% is 4,000 to 6,000 generating hours pn the cell.

Cells can fail around 6,000 hours.
