I have had the Intex SWG on a small 2,000 gallon pool for about a month or so now. I purchased a larger 1,000 gph pump to assist it. The SWG ran fine for a few days then it gave me a high salt warning. I drained 20% and added fresh water. I retested the water and the salt level was right in the middle. Then I received the code 92 high salt again. I tested the level and it was still right in the middle. I soaked the unit in vinegar per Intex instructions and nothing. They sent me a replacement Anode a few days ago. I swapped the Anode out and it ran perfect. This was about 5 days ago. Today I went to boost the SWG and it started giving me the error again. My salt level is fine. I unplugged the unit for about 30 seconds and retried it. Same result. Any thoughts? I should clarify I am using the Aqua Check? Test strips.
