4.5 Preparing Specialty Coffees (e.g., Latte, Cappuccino)

To prepare milk-based beverages:

1. First, prepare milk froth or hot milk using compatible milk capsules (e.g., D*olce G*usto or S*tarbucks milk capsules).
2. Then, brew a shot of espresso using your preferred coffee capsule or ground coffee.
3. Combine the espresso with the prepared milk according to your desired recipe. Refer to capsule manufacturer websites for specific fancy coffee ratios.

5. Maintenance and Cleaning

5.1 Daily Cleaning

• After each use, remove and empty the drip tray and used capsule/ground coffee adapter. Wash them with warm, soapy water and rinse thoroughly.
• Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
• Empty and rinse the water tank daily.

5.2 Cleaning Reminder

The machine is equipped with a cleaning reminder feature to ensure its longevity. When a cleaning cycle is recommended, all indicator lights will flash rapidly, and only the brew button will remain functional. This is not a malfunction. It indicates that descaling and cleaning are required to restore normal operation.

5.3 Descaling

Regular descaling is crucial to prevent mineral buildup and maintain optimal performance. The frequency depends on water hardness and usage. Follow these general steps for descaling:

1. Empty the water tank and fill it with a descaling solution (e.g., white vinegar and water, or a commercial descaling agent) according to the descaling product's instructions.
2. Place a large container under the coffee spout.
3. Run several brewing cycles without a capsule until the water tank is empty.
4. Rinse the water tank thoroughly and fill it with fresh water.
5. Run several more brewing cycles with fresh water to flush out any remaining descaling solution.
6. Repeat the fresh water rinse cycles until no descaling solution residue is detected.

Note: Always refer to the descaling solution manufacturer's instructions for specific ratios and procedures.
