On some units, simply press the button next to “filter” on the control panel. On other units, turn it off at the on/off switch or the time clock. In addition, flip the breaker for the control panel or turn off the control panel. Then, unplug the salt cell, as well. [1] X Research source
Unscrew both sides of the salt cell to remove it. It should have large screw-in unions on both ends. The unions will be the same size as the pipe. As you unscrew, be careful, as water will leak out. [2] X Research source
Tip the salt cell up to look inside at the metal plates. Check for mineral deposits. [3] X Research source
If you have a newer salt system, the cell may not even need cleaning out, as these systems have built-in ways of keeping deposits from building up. Watch for the signal. Some systems have an automatic monitor to remind you when to check your salt cell.
Don’t get the end of the plug wet, as that part is not waterproof.
Start with five parts water to one part acid. Never add water to acid. Always add the acid to the water. While occasional cleaning of a cell is acceptable it’s best to only do so when required. While the acid does remove any Scale it also damages the plates inside of the cell itself thus reducing the life.
For the moment, pour the solution back into the bucket.
