In order to protect your glassware against glass corrosion in an optimal way, you have to
perform the same hardness settings, which you have made in the control panel, with the
regeneration setting switch.
For example, if you have adjusted to “3rd level” in the control panel, also set the regeneration
adjustment switch to 3rd level.
