obstructions, reducing the efficiency of the coffee
machine.
The coffee machine has a system to monitor the
quantity of scale. When the scale builds up excessively,
the ON/OFF coffee indicator light starts flashing. This
means the appliance should be descaled.
To descale, always use special commercially available
descaling products for drip coffee machines. If these
products are not available, you can also follow the
procedure below.
1. Pour four cups of water into the carafe;

and pour the solution into the drip coffee water
tank;
3. Place the carafe on the warming plate;
4. Press the drip coffee ON/OFF switch, percolate the
equivalent of one cup and then switch off the
appliance;
5. Leave the solution to work for 15 minutes. Repeat
operations 4 and 5 again.
6. Turn the appliance on and run off the water until the
tank is completely empty.
7. Rinse by operating the appliance with water only at
least 3 times (3 complete tanks of water).
Failure to clean as described above invalidates the
warranty.
