Low amps/cleaning an Autopilot PPC1 salt cell

Hello,

I've recently gotten my pool from a total swamp state to clean water and I've been having an issue with my salt cell. At first it would warn of low amps (26V 2.8A). So I decided to clean the cell using water and muriatic acid according to instructions in the manual. I don't believe there was much or any calcium build up because it didn't bubble much at all and I don't see any white stuff on the blades.

Looking at the blades in the salt cell I see what appears to be black or maybe dark green build up in between the blades. I thought maybe it was some kind of algae considering the pool was in a swamp state. Even though I couldn't find any information on this, I tried putting some liquid chlorine in the cell to clean it. Adding the liquid chlorine caused it to bubble a lot, I only let it sit a few minutes out of fear that it would mess up the cell even more, but it was obviously reacting to something. There was a large chunk of gunk near enough to the edge that was stuck in between two blades that I managed to get out with a plastic straw.

I also noticed that the two outter most blades were slightly shorter than the middle blades.

I reinstalled the salt cell and cleaned the connectors and cell cord contacts as well as I could. The salt cell appeared to be working again fine (17V 4.9A) with no warning messages all evening.

This morning I go out and check and I have a different error message "warning! check/clean cell" and its running at 25V 3.1A. Previously it was a message specifically about "low amps". EDIT: Now it cycles between "check/clean cell" and "low amps" messages.

Should I try cleaning with liquid chlorine again? Or some kind of way to manually clean between the blades? Really trying to avoid spending $400+ on a new salt cell when this one is only 3 years old.

Thanks!

I think your cell is depleted.

Call these guys and see what they think...

 
I know the post is a year old but did you get this fixed? I'm having the same issue. Thanks in advance
I ended up buying a new cell. Fixed the problem for me.

I had a bad habit of leaving the pool unattended and let the pH creep too high pretty often, which I think contributed to the original cell's breakdown. So I try to be more consistent with pH checks and adding muriatic acid regularly.

My PB gave me a new cell this morning and it looks like the red light and warning sound stopped. It only been 3 years and it had 23,000 hours.
He just told try to run it for only 12 hours and let the units adjust automatically.
You think is the PH?
I like to run my PH high at 7.8 all the time.
TA @ 70/80, CYA @70/80.
No Scaling in the cell. Never
 
7.8 isn't a problem for the cell. Make sure you have the proper amount of salt which makes it more efficient.
Always 3200 to 3300 ppm. From opening to closing and tested with TFtestkit.
My neighbor's has the same set up but he has the DIGI Autopilot set up which I'm assuming is bigger than mines. My pool is 20k Gallons(maybe the neighbor's is 15k because of no deep end buy he gets like 5 to 6 years out his cell.
 
You think is the PH?
I'm no expert on this stuff, but my cell lasted about 3 years and didn't have any noticeable scaling as well. When I mentioned letting the pH get too high, I meant leaving the pool unattended for possibly weeks at a time where the pH would be well above 8.0 and the pool turning green.

Whether or not that contributes to cell breakdown, I can't say for certain, but I try to be on top of things now. Too early to tell if I'll get more than 3 years out of this one or not.

I do run my SWCG for 13 hours per day in the Summer (Southeast U.S. - very hot, sunny, and humid for a large portion of the year) so I don't know how many years I can realistically expect with that much usage.
