We recommend using De'Longhi approved descaler which is available through customer service. Follow this procedure: 1. Fill the tank with the descaling solution and dilute the solution with water, following directions on the descaling solution package. 2. Press the on/off button and wait for the OK light to switch on. 3. Make sure that the filter holder is not attached and position a container under the boiler outlet. 4. Press the coffee button and allow about 1/4 of the solution contained in the tank to flow out: every now and again turn the steam knob and allow a small amount of solution to escape; then interrupt by pressing the button again and leave the solution to act for about 5 minutes. 5. Repeat point 4 another 3 times, until the tank is completely empty. 6. To eliminate residues of the solution and lime scale, rinse the tank well and fill it with clean water (without descaler). 7. Press the coffee button (fig. 6) and operate the appliance until the tank is completely empty; 8. Repeat operations 6 and 7 again. 11
