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 used (including the amount required for producing steam), and will then let you know when a descaling cycle is necessary. To measure the hardness of your water, use the test strip that is included in your installation kit. ^ Place the test strip under your kitchen tap for a 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 (40°D), 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. 30
