I'm having an issue with an Intex CS20110 SWG pump. Earlier today I was getting a low salt warning from the pump. I know the low salt warning is false because I've tested the salinity of the water, plus being in the pool a few times already, I can taste a little bit of salt in it. This has happened once before and the warning was triggered by buildup in the titanium electrode. I noticed some more building and decided to clean it.
So, per the manual, I doused it in vinegar and let it sit for about an hour or so and all the buildup disintegrated into nothing. I rinsed the electrode off, put everything back together, and fired the pump back up. About a minute of running the pump shuts down and the red service light on the pump comes on. I reset the breaker on the GFCI outlet and tried again....same thing. Next the pump was shut down for a while to cool off (not sure if it was overheating) and it just shut down all the same after restarting. I cleaned the titanium electrode again and also the copper electrode for good measure (it needed it anyway), but alas the pump shut down once again.
A kicker to this is that if I power up the pump and turn off the saltwater system it works with seemingly no problem at all, but now I am not generating any chlorine. A little while afterwards I realized that when I cleaned the titanium electrode I removed it from the casing. Not really sure why I did it this way since the last time I cleaned it I left it in the housing and filled that chamber up with vinegar. There also wasn't very much buildup to speak of on the electrode. There was probably only half of what was there since the last time I cleaned it, yet the low salt warning went off anyway. I'm wondering if the way I cleaned it might have damaged an already ailing unit. I didn't clean it with anything except vinegar and water. No scrubbing or anything like that.
So my question is - would it seem to be that my titanium electrode is bad? Is it possible I damaged it when I removed it from the housing even though I didn't physically clean it with anything?
The pool came with the home I bought last year and the previous home owner had the pool for about three or four years. I'm not sure if he ever replaced any of these parts. I know for certain the pump is the original pump that came with the pool.
Thanks in advance for taking the time to read and/or answer my question.
