Descaling

It is advisable to clean the calcium from the machine every 200 cups of coffee. 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 water using 1 litre of water;

2.Dissolve 2 spoonfuls (about 30 grams) of citric acid in the water (available from chemists);

3.Press the ON/OFF button (fig. 4) and wait for the OK indicator light to come on.

4.Make sure the filter holder is not attached and position a contai- ner under the outlet.

5.Press the coffee button, half empty the tank and every now and then rotate the steam knob to allow a little of the solution to run off. Then switch off by pressing the button again.

6.Leave the solution to work for about 15 minutes, then run off the rest of the water in the tank.

7.To eliminate residues of the solution and scale, rinse the tank well, fill with clean water and replace in its housing. Press the coffee button and operate the appliance until the tank is completely empty;

8.Press the button again and repeat the last operation.

Repairs for malfunctioning caused by problems of calcium build-up are not covered by the guarantee if the descaling process described above is not carried out regularly.
