Cleaning And Maintenance - STARBUCKS Sirena User Manual

9 CLEANING AND MAINTENANCE

Warning! To avoid serious injury and electrical shock, it is essential to turn off and unplug the
Sirena, and allow it to completely cool off before cleaning.
Cleaning and maintenance operations can only be carried out when the machine is cold and disconnected
from the power supply.
• Do not immerse the machine in water or place any of its components in a dishwasher.
• Do not use sharp objects or harsh chemical products (solvents) for cleaning.
• Never use harsh cleaning agents, especially those containing alcohol, solvents, or abrasive materials on
your Starbucks Sirena Espresso Maker.
• Wipe all external surfaces with a damp cloth; then wipe the surfaces dry to preserve the exterior of your
machine.
• Do not dry the machine and/or its components using a microwave and/or conventional oven.
• We recommend cleaning the water tank and filling it with fresh water daily.
• After heating or steaming a beverage, always dispense a small amount of hot water out of the steam wand
to clean the inside of the steam wand, and clean it on the outside with a damp cloth.
- If you notice a residue build-up on the tip of the steam wand, or if water flow out of the steam wand seems
to be restricted, submerge the steam wand in a tall container of hot water. Allow the steam wand to soak
in this hot water overnight. Then clean the steam wand with a damp cloth, and run some water through
the steam wand to remove any internal residue. (Fig. T and Fig. U) This preventive measure can reduce or
eliminate the need for more intensive cleaning; however, the machine must still be descaled on a regular
basis (section 10).
• Empty and clean the drip tray daily. (The drip tray and grill are dishwasher safe, but we recommend hand-
washing both parts.)
• To clean the portafilter, proceed as follows:
- Remove the filter (10 or 12) from the portafilter. Immerse it in hot water and wash it thoroughly, making
sure to remove any remaining coffee grounds from the filter basket holes. If necessary, use a small
pin to clean out any clogged holes. (Fig. V)
- If soap is used, rinse thoroughly.
- If inserted, remove the rubber gasket adapter (11a) and plastic support peg (11b) and wash them thoroughly.
- Rinse the internal part of the portafilter thoroughly, making sure making sure to remove any remaining
coffee grounds by pressing on the inside part of the portafilter, as shown in Figure W.
• At least once per month, clean the brew head from any coffee grounds, using a damp towel.
• Descale your machine regularly, following the descaling instructions in section 10 of this manual.
• Turn off the machine by pressing the power button (15), and unplug the machine from the power outlet
after each use.
