Salty dishes ⇐ Beko

[Svetlana]

Beko dishwasher is new. Water hardness is 2, the salt indicator is constantly on, I added half a pack of salt, as a result the dishes are white and salty after washing, I use finish all in 1 tablets, maybe I don’t need to add salt? If you don’t add salt, the dishes are perfectly clean. I couldn’t find a description of how much salt to add either in the instructions for the machine or on the salt box. Tell me, who knows what to do?
