One problem that users have found with Intex saltwater chlorine generators is repetitive Low Salt Level errors – even when salt levels in your water are adequate. This is due to the chlorinator cell building up scale on the electrical plates. When you purchase a unit new, it should last several months without this problem coming up. However, you will eventually begin to get the scale and “Low Salt” error codes every 6-8 weeks after that. Fortunately, this problem is fairly simple to fix.
To correct this problem, you must disassemble your unit and remove the generator cell. If you look into the cell, you will see several metal plates that are likely overrun by a white scale. In some cases, you may be able to remove this scale with the spray from a water hose, however it’s probably a better idea to perform the full cleaning outlined below. Otherwise, you’ll just have to clean the unit again in a week or two.
To fully clean your generator cell, mix 1 cup of vinegar with about 2 gallons of water. Place your generator cell in this mixture overnight. The next day, you will be able to remove almost all of the scale by spraying it with your water hose. An additional technique is to scrape or push the scale out from between the plates with a non-metal object. Some ideas might be a popsicle stick, or a piece of plastic. The key is to find something with the right thickness. One suggestion to try is a piece of plastic cut out of the front cover of an old Compact Disc case. You do want to get as much of the scale out as possible before scraping so that you minimize the chances of damaging the metal plates in your cell.
