Correct hardness setting for Water-Right Impression Series Sanitizer Plus

[GregoryWright]

We have a Water-Right Impression Series Sanitizer Plus Softener, and our water has been "just right" for a number of years, up until about three weeks ago. Around that time the water went _really_ soft, leaving my wife in particular feeling like she can't get soap completely off her skin or hair. If this is something that I can address through the use of a hardness test and updating the settings myself, I'd prefer to do that than calling out a plumber for obvious reasons.

The problem is that while Water-Right has a great video showing how to make adjustments to the unit's settings (including hardness) on YouTube:

• There is no guidance in the owner's manual for choosing a setting
• I have not been able to find any guidance online regarding the setting
• Water-Right has not responded to my request for information

So does anyone know this unit, and know what I would need to do in order to adjust the setting properly? Or know enough about the unit to tell me why I should call in a plumber with experience on these units instead of trying to address it myself?

Thank you very much in advance.
