Question: Do I need to add salt even though I have a central softener for the household water supply?



Not necessarily, although you would need to check that the water hardness level is at least 25°F (French degrees) first. However, we recommend adding salt every time you use the dishwasher as it helps the softener maintain its efficiency and prevents marks from being left on your dishes.
