Soft water is required for dishwashing to prevent the build up of scale (lime deposits) on your dishes and in your 
. If hard water is used for dishwashing, you will notice glasses will become opaque, dishes will become spotted or have a white film on them and your dishwasher will become less efficient over a period of time. Tap water above 100ppm must be softened for dishwashing for optimum wash performance.
models DD603H and DS603H are fitted with a water softener which is designed to remove the calcium and magnesium ions that cause water to be ‘hard’. The water softener will automatically remove the hardness from the water using a salt solution. The amount of salt required will depend on the local water hardness. Your local water company will be able to provide you with the information on the water hardness in your local area.
To Ensure Optimum Performance of the Water Softener
The water softener must be set to the correct local water hardness and must always be filled with granular salt made especially for dishwasher water softening systems. We do not recommend the use of cooking salt like table or rock salt or pellets as they may contain impurities that will impair or diminish the life of the water softener.
