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 (the light on the button comes on - fig.
4) and wait for the “coffee ready” 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 switch and allow about 1/4 of the solution
in the tank to flow out, rotating the steam knob every now and
then to deliver a little solution. Then stop the flow by pressing the
switch again and leave the solution to act for about five minutes.
6.Repeat point 5 a further three times until the tank is completely
empty.
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.
