Water hardness levels and your kitchen appliances

Water 'hardness' is often referred to in operating manuals for household appliances such as dishwashers and kettles. This terms refers to the concentration of calcium and magnesium salts in the water, which can attach to surfaces and cause a hard, flaky scale.

Water hardness, or the level of these salts is very low in Melbourne's water (varies from 10mg/L to 70mg/L), so softeners are not required for household appliances.
