Question: Do I need to add salt to my Smeg dishwasher?

You only need to add salt if if your water hardness level is above 38°F (French degrees) as the resin-based water softener needs salt to maintain its efficiency. Most metropolitan areas in Australia have soft to medium water. The most populated hard water areas in Australia are rural areas around Adelaide and parts of Brisbane and there is a higher likelihood for hard water if you are on tank water. If you have hard water, we also recommend checking and cleaning the central softener for the household water supply as well.
