CLEANING THE ESPRESSO BOILER OUTLET About every 300 coffees, the espresso boiler outlet must be cleaned as follows: • check that the coffee machine is not warm and the plug is detached from the mains; • using a screwdriver, unscrew the two screws that hold the outlet of the espresso boiler (fig. 19); • clean the boiler with a damp cloth (fig. 20); • clean the outlet thoroughly in hot water using a brush. Make sure the holes are not blocked. If necessary, clean with a pin. • rinse the outlet under the tap, still scrubbing it; • replace the outlet of the espresso boiler. Failure to clean as described above invalidates the guarantee. DESCALING You are recommended to descale the coffee machine about every 300 coffees. You should use a commercially available product specifically for descaling espresso coffee machines. If you cannot obtain such a product, you can also follow the procedure below. 1. First clean the coffee machine, turn off and unplug from the outlet. 2. Fill the carafe to the brim. 3. Dissolve 1 spoonful (about 10/15 g) of citric acid; 4. Pour the solution into the boiler. 5. Replace the boiler cap and leave the solution to work for about 30 minutes. 6. Place the selector in the "LIGHT" position. 7. Put the filter and filter holder in position (without coffee). 8. Position the carafe on the drip tray. 9. Plug into the outlet. 10.Turn the coffee machine on. After a few min- utes, the hot solution will start to flow through the filter holder into the carafe. 11.Place the steam tube in a glass or cup. Open the steam knob for a few seconds while the descaling solution flows through the filter holder. This cleans all residues of milk from inside the tube. 12.Close the steam knob (the descaling solution will continue to flow into the carafe). 13.When the solution stops flowing into the carafe, turn off and allow the machine to cool down. Remove the filter holder, filter and carafe and rinse with hot water. 14.To remove traces of descaler, perform at least 2 coffee-making cycles without coffee.
