Jandy aquapure 1400 dead after less than 4 years

I am somewhat disappointed. I have zealously maintained my chemistry since we built the pool but it looks like my salt cell is dead. The cell has never needed cleaning for calcium buildup, my CSI is always slightly negative yet the three plates connected to the power connections have all gone black / blue and the control unit is reporting code 120.

I spoke to my local jandy rep and he said to clean it with acid. There were no bubbles and it made no difference. I measured 38V accross the cell and 105mV at the cell current test point. My conclusion is that I need a new cell.

Now the reason for my dissapointment. When the pool was built I specified the PLC 1400 cell that is intended for pools upto 40k gallons. Because my pool is 13.5k gallons I thought that the cell would last much longer because less chlorine would be needed. It seems that I'm wrong here.

I don't want to change to liquid chlorine - too much faff even with an injection pump.So would I be better off replacing the cell with the smaller and hopefully cheaper PLC 700 cell? Or would that last me 2 years at best?

Water conditios for reference:
Cl is typically 4-6ppm assuming I brush enough!
pH is always between 7.2 & 7.8, typical is 7.5
TA is typically 60
CH is between 300 & 375
CYA is between 50 & 70
Salt is between 2800 & 3400

Do you see the two small screws by the prongs?

Remove the screws and pry off the little plastic part that has 3 holes that go over the prongs.

Is the center prong loose?

I have a 24k gallon pool with Jandy 1400 as well. It is on its 3rd cell in the 10 years since the pool has been installed, the most recent being this past spring. 4-5 years is the average from what I've read on multiple forums regardless of care. James comment alludes to the exact problem I had on both of the ones I had to replace. The pins that the power cord press onto were corroded and detached from the plates inside. Strikes me as a design defect and an expensive one to consumer as a well.

I found, bought and installed a "generic" drop in replacement this past spring that has been working well so far for $300. It works best right at salt level of 3500. Salt Pool Store. I am not in the business, not affiliated in away. Just a pool owner looking to save a buck and help my fellow pool owners.

As I posted on the other thread , it's not a good idea to order from that particular seller IMO. Their warranty is non-existent. The gray cells are CompuPool cells and most likely the retailer will force buyers to contact Australia directly for a warranty replacement and for most people that doesn't go very well.

I will happily defer to those that know what they are talking about concerned warranty issues with this vendor. However, I will be happy with the product I mentioned above and order again if I get even 2 years of use out of it as the price was less than half of the Jandy 1400.
