When do I need to add dishwasher salt?

The limescale level in the water determines how much salt needs to be added to the dishwasher - the harder the water, the more salt is needed.

Information about the water hardness level can be found on the municipality's website. The water hardness level is measured in °dH. The recommendation for when you need to add salt varies between different dishwasher models, read more in the dishwasher's instruction manual. The dishwasher indicates on the control panel with a star-like symbol when salt needs to be refilled.
