I was reading other problems and mine are a bit different. My second year at house with pool, I think everything was installed in 2010. No issues last summer. The only thing that is different is that I replaced the mulch with rock (the reason I mention is because the ground wires were in the mulch).
No chlorine is being produced this season. No errors, all lights appear as though it's operating normally. I took the cell out to clean and it looked fine. Acid treatment resulted in no bubbles. Rinsed and put it back. Every time I test the jets I see no difference in Cl vs the pool. Except, I got a reading of 7ppm at jet, 2.5ppm in pool on Friday. That was a one time thing and it's back to doing nothing but it shows me the cell can work. I found the troubleshooting manual on this site (thank you) and I measured all of the voltages. Looked fine, a little high at times but nothing looks too weird. Cell voltage is out of range high. Here are my test results with specs in ().
Back board Front Board At cell
1-8 79.6V (75) A-C 20.6V (21) center-left 30.0V (22-28)
2-7 69.5V (65) K-H 0.119V (0.120) center-right 30.0V (22-28)
3-6 20.7V (21)
4-5 0.126V (0.120)
Cell 30.5V (22-28)
Salt 3.2g/L by sensor, 3.4g/L by Taylor test. Temp 80F.
Any ideas why this isn't working? I know it's near the end of it's life but it's clean and I have no errors and good test results. Is the high cell voltage any indication? It seems the 4-5 and K-H voltages indicate that the cell is OK (6amps). I really don't want to buy a $500 replacement cell if there's some simple explanation (plus it clearly produced Cl last Friday for a brief time). I don't see anyone replacing their cell without the service light coming on.
Any help would be appreciated, thanks.
