User Manual Fisher & Paykel DD24SCTX9 N Single Dishdrawer Dishwasher

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.
