On Saturday (7/7), I ran my Intex Krystal Clear SWG (CS8111) for about 4 hours, then my kids played in the pool for several hours. After my kids finished playing, I turned the SWG back on that night for a couple of hours. Right after turning the unit on, it started flashing code 92 (high salt). We have only had our pool for a little over 3 weeks and have not added any salt since setup. On Friday (7/6) our local pool store tested the salt level at 3000 ppm which is optimum for our pool. I tested the salt level on Sunday using test strips and got a reading of about 3100 ppm. On Sunday afternoon, I turned the unit back on and ran the SWG for about 4 hours and it worked perfectly. Today (7/9) I turned the unit on and ran the SWG for 4 hours and it worked perfectly. My kids played in the pool and then I turned the unit back on tonight to run the SWG for a couple of hours. Again, it immediately gave a code 92 error.
I am not sure what is happening. It was working perfectly until I unplugged the copper bars on Saturday morning. I didn't want the unit to continue generating copper because we are already at 0.3 ppm, and it continues to rise. Does anyone know if unplugging the copper bars could cause this intermittent code 92? I am sure that the salt level is not really too high since it works perfectly sometimes. Also, if the chlorine level is already high enough and you try to run the SWG, could that cause the unit to mistakenly give a code 92 error? I am concerned because we would like to go on vacation, and I have no idea if this error will occur while we are gone and what will happen to our filter pump / SWG combo unit if it does. I appreciate any ideas as to what may be going on.
