Water Hardness and Dishwashing

What is Water Hardness?

Hard water is water with a high concentration of minerals such as calcium and magnesium. In soft water, this
concentration is low. Water hardness varies by geographical location.

How does Water Hardness Affect Dishwashing?

• Hard water can be detrimental to the performance of your dishwasher. Over time, glassware washed in hard
water will become cloudy and dishes will become spotted or covered in a white film. Using very hard water can
cause dishwasher parts to fail over time.
• Naturally soft or softened water has no detrimental effects if used with the correct amount of detergent.
However, excess detergent combined with hot, soft water may cause irreversible etching on glassware. Etching
first appears as a rainbow-coloured film and — if allowed to continue — can make glassware permanently
opaque.

What Can I Do to Minimise any Detrimental Effects?

Contact your local water company to find out about water hardness in your area.

stop the spray arms from rotating.
• Sharp or pointed items must be placed
horizontally or with sharp edges/points facing
down to avoid risk of injury.
