Settings
Water hardness
The hardness of the water 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 it yourself using the enclosed test strip.
^Dip the test strip in the water for 1 second and shake off any remaining water. The result is visible in about 1 minute.
If the water hardness is greater than 40 gr/gal, the water must be descaled more often than displayed. Calcium will build up faster than at a lower water hardness and may damage the machine.
