English Descaling Calcium buildup ("scale") should be cleaned from the machine every 4 months as this deposit could compromise the quality of the espresso as well as the functioning of the machine components. The formation of scale depends on the local hard-water conditions and on how much the espresso machine is used. It is recommended that specific (store-bought) products for descaling of espresso coffee machines be used. If such products are not available, it is possible to proceed as follows: 1. Fill the tank with 1 quart of water. 2. Dissolve 2 spoonfuls (about 1 ounce) of citric acid in the water (available at pharmacies). 3. Turn on the upper switch and wait until the green "OK" light comes on. 4. Check that the filter holder is not attached and place a container under the outlet of the machine. 5. Turn on the lower switch and allow half of the solution in the tank to flow out. Then stop the flow by turning off the lower switch. 6. Allow the solution to sit for about 15 minutes, then start up the flow again and repeat until the tank is completely empty. 7. To eliminate the remaining solution and the calcium, rinse the tank well, fill it with clean water and replace. 8. Turn on the lower switch and allow all of the remaining solution in the tank to flow out. 9. Turn on the upper switch and repeat number 7 and 8 one more time. Note: Repairs for malfunctioning caused by problems of calcium build-up are not covered by the warranty if the descaling process described above is not carried out regularly. Cleaning After Long Periods of Non-Use Wipe the espresso machine and all accessories with a soft, damp cloth. Follow instructions in the "Descaling" section and the "Before Using for the First Time" section to prepare the machine for usage. 10
