Determining the water hardness
The hardness of the water (tap or bottled) used in the coffee system must be determined and programmed into the appliance. The water hardness will determine how frequently the unit must be descaled to maintain the coffee system properly. The machine monitors the volume of water passing through it in conjunction with the hardness of the water and will indicate when descaling is necessary. Your local water authority can tell you the hardness of your tap water or you can measure the hardness yourself using the enclosed test strip.
^Dip the strip in your drinking water for one second, then shake off excess water.
The result will be evident after a minute.
If the water hardness is greater than 40 gr/gal (700 ppm), the water must be mixed in equal parts with
