Over time, the continuous heating up of the water used to make the coffee leads to lime scale building up in the inner circuits of the appliance.

When the appliance displays the message:

You should perform the descale cycle. Proceed as follows:

• make sure the appliance is ready.

• press the button (the light over the button comes on) then press the button repeatedly until the appliance displays:

			DESCALE YES
•	Press the	button to start the descale program.

•Empty the tank and pour in the contents of one bottle (4.2 fl. oz.) of DURGOL descaler plus 34 oz. of water. For subsequent descaling operations, descaling solution can be purchased from authorized tech- nical service centers.

Note: Make sure splashes of descaler do not fall onto surfaces sensitive to acid such as marble, limesto- ne and glaze.

•Place a plastic or glass container with a minimum capacity of 50 oz under the hot water spout (Fig. 3);

•Turn the steam knob half a turn counterclockwise (fig.3). The descaling solution will run out of the cap- puccino frother and start to fill the container underneath.

•The descale program automatically performs a series of run offs and pauses to remove lime scale depo- sits from inside the coffee maker.

•After about 30 minutes, the appliance displays:

•Reposition the tank.

•Empty the collection container (under the cappuccino frother) full of liquid and then put it back under the cappuccino frother.
