Do I live in a hard water area?

53 Hard Water Area

Find out what sort of water your area has, and read about protecting your machine from hard-water minerals. 

We are incredibly lucky to live somewhere where water is available to us whenever we want it - but have you ever thought about the difference in the water that comes out of your tap? No two glasses of water are exactly the same and the main reason is usually the hardness of the water. What exactly does this mean?

To give you a greater understanding of hard water and its effects, we’ve put together this hard water hub to explain exactly what it means to live in a hard water area, the affects it can have on your dishwasher, and how you can overcome them.


What exactly is hard water and how does water become ‘hard’?

Rain water is naturally soft, however, as this water makes its way through the ground and into the waterways, and eventually to our taps, it picks up dissolved compounds such as calcium and magnesium. These minerals are hard to filter out when being turned into tap water in water-treatment plants, meaning the type of rocks found in any given location determines how hard or soft the water will be.

Is hard water harmful to my health?

In the United States the National Research Council has proved that the appearance of calcium and magnesium in hard water means that they could serve as small dietary supplements.

Although hard water is harmless to drink, it’s not so good for household appliances like dishwashers, and for keeping them clean.

What does hard water do to my dishwasher?

When hard water passes through the dishwasher, the minerals in the water build up on the heating elements, most notably as limescale. This not only makes it a lot harder for the dishwasher to clean the dishes, but it can actually make them look worse as the minerals from hard water can deposit on dishes and glassware, causing unsightly cloudy spots.
