17 REMOVING MINERAL DEPOSITS
To keep the machine operating efficiently, it is necessary to regularly clean the mineral deposits left by the descaling
water.
This operation must be carried out at least every thousand brewings or, in absence of brewing records, every three
months, using exclusively the Evoca descaling product (product code 21002666). You can buy Evoca Descaling product at
the following link: https://ecommerce.evocagroup.com/ Using other descaling products or disregarding the above
mentioned intervals may lead to brewing or operational faults.
In order to carry out the procedure for removing the mineral deposits, proceed as follows:
1. Fill the water tank with 0.25l of Evoca descaling product and fill up with fresh water up to the MAX level.
2. If not yet done, switch on the machine with the power button 9 and press any of the brewing buttons 3, 4 or 5 to exit
the stand-by mode: the LED indicator 10 flashes red during warm-up. When the machine is ready, the indicator 10 and
the brewing buttons are lit up in white.
3. Place a suitable capacity container on the cup holder grill 7.
4. Discharge any capsule remained in the mechanism by opening and closing handle 1.
5. Press the Caffè Lungo brewing button 5.
6. Wait for 2 minutes.
7. Repeat steps 5 and 6 until the liquid in the tank is exhausted.
8. Rinse the tank and fill it with fresh water. Empty the container placed on the grill and the drip tray 8.
9. Press the Caffè Lungo (Long coffee) brewing button repeatedly for brewing until the water in the tank is exhausted.
10. Refill the tank with fresh water and empty the drip tray 8.
11. The machine is now ready to brew normally.
