First Use & Setup

Before first brew, clean the machine by running water through the system.

1. Remove all packaging materials and stickers.
2. Fill water tank with fresh cold water and place back into machine.
3. Place empty portafilter (without coffee) into group head.
4. Turn power ON. Place a cup under the steam wand and portafilter.
5. Run water through both the brew head and steam wand for 2 minutes to flush internal lines.
6. Wipe all exterior surfaces with a damp cloth.

CAUTION! Do not add coffee grounds during initial flush. Ensure machine is plugged into a dedicated outlet.

Brewing Espresso

For best results, use finely ground espresso coffee.

1. Fill water tank, ensure drip tray is empty, and power ON machine.
2. Preheat: Allow machine to heat for 5-10 minutes until ready light is steady.
3. Grind & Dose: Fill filter basket with ground coffee (approx. 7g for single, 14g for double). Level and tamp firmly.
4. Insert portafilter into group head and lock securely to the right.
5. Place pre-warmed cup(s) under portafilter spouts.
6. Press Single or Double Shot button to start extraction. Brew will stop automatically at programmed volume.
7. To stop manually, press the same button again during extraction.

Tip: For optimal crema, use fresh beans and warm cups. Adjust grind fineness if extraction is too fast (sour) or too slow (bitter).

Using the Milk Frother

To create frothed milk for cappuccinos or lattes.

1. Ensure machine is on and heated. Fill a pitcher 1/3 full with cold milk (whole milk froths best).
2. Turn Steam/Hot Water knob to STEAM position. The steam light will illuminate.
3. Wait 30 seconds for full steam pressure. Purge steam wand briefly into drip tray to clear condensation.
4. Submerge steam wand tip just below milk surface. Turn knob fully open.
5. Lower pitcher as foam rises to keep wand tip near surface for frothing. For heating only (latte), keep wand deeper.
6. When milk reaches desired temperature (too hot to touch), turn knob to OFF.
7. Wipe steam wand immediately with a damp cloth, then purge briefly to clear milk residue.

WARNING! Steam is extremely hot. Never touch wand or point it at people during use.

Cleaning & Maintenance

Regular cleaning ensures performance and longevity.

• Daily: Empty drip tray and rinse. Wipe steam wand and group head with damp cloth after each use.
• Portafilter & Baskets: Rinse with warm water after each use. Do not use soap on filter baskets.
• Water Tank: Remove, rinse, and refill with fresh water daily.
• Exterior: Wipe with soft, damp cloth. Do not use abrasive cleaners.
• Descaling: Perform every 2-3 months or as needed based on water hardness (see Descaling section).

CAUTION! Unplug machine and allow to cool completely before any cleaning beyond wiping exterior.

Descaling

Mineral buildup from hard water can affect performance.

1. Prepare descaling solution as per product instructions (use espresso machine descaler).
2. Fill water tank with descaling solution.
3. Place a large container under both the group head and steam wand.
4. Turn machine ON. Run solution through both the brew head and steam wand until tank is half empty.
5. Turn machine OFF and let it sit for 15 minutes.
6. Turn ON and run remaining solution through the system.
7. Rinse tank thoroughly and fill with fresh water. Run at least two full tanks of clean water through both functions to flush.

Note: Descaling frequency depends on water hardness. More frequent descaling is needed in hard water areas.

1. To program Single Shot: Press and hold the Single Shot button. Extraction will begin.
