Full Answer

Dishwasher salt is specifically designed to be used in dishwashers. However, not all dishwashers are equipped to handle dishwasher salt. This product can be used only in dishwashers that feature a water softener container. In the Bosch dishwasher line, this includes models 800+ and the SGE63E Series. These machines have resin beads with attached sodium ions. These beads are stacked in a column. When the hard water passes down the column, the calcium and magnesium ions, which cause the water to be hard, swap places with the sodium ions. Thus this column of beads grabs hold of all the ions that were compromising the performance of the dishwasher.

Over time, the resin beads reach maximum capacity. This means that they can no longer hold any more calcium and magnesium ions. Once this point has been reached, it is necessary for sodium chloride to be added. This is where the dishwasher salt comes in. This salt removes the calcium and magnesium ions, and the beads are able to become fully charged with sodium ions.
