I have an Aquarite with a T-Cell-15 for a 15,000 gallon pool. The cell is 3 years old. I believe the PCB and display board may be the original (over 10 years old.) Over a week ago, I noticed the check salt and inspect cell lights were on continuous.
I have tried inspecting and cleaning the cell. I did not see any build up, but tried spraying it out, then cleaning with 4 parts water, 1 part muratic acid. Then, I recalibrated it and saved the salinity value that it settled on. It was still generating since the value was 2800.
The next day I noticed a rat chewed through the flow sensor cable, so I repaired the cable, and it was generating chlorine again. No error lights on. Only solid power and generating lights.
The next day after that and up to this point, I noticed the salinity reading drops over night and into the day. For example, it read 2800, then dropped to 1600. I had Leslie's test the water a couple times and the salinity is 3000. When it drops low, it is no longer generating.
Last night, I tried locking the salinity to 3000 before it completed recalibration just to get the cell running until I fix the issue. This morning it shows 400.
I did not see any noticeable burning on the face of the boards. The thermistor looks old, but it did not crumble when I tapped on it and does not appear to be cracked.
I plan to take the cell up to Leslie's to have them test it. Does this sound like a salt cell problem or PCB?
I noticed a few days ago the product name shows 88-5 and the software revision shows r8.80. Today, it shows 88-0 with revision r8.80. There is also NOT an option to set the tcell type (I will have to look later to see if there is a jumper on the board.)
Is this just an old Goldline PCB? It is strange the product is not AL-(a number).
