Before first use, remove and rinse the water tank, milk carafe, brew unit, and milk frother. Make sure the water tank, milk tube, milk frother, brew unit, grounds container, internal drip tray, and external drip tray are all properly installed. Fill the water tank to the MAX line and add coffee beans to the bean hopper, up to 180 g / 6.3 oz. For a new machine, we recommend starting with a grind setting no lower than level 8. Each time the machine starts, it will run an automatic cleaning cycle to prepare the system for use.

For first-time use, we recommend setting the grinder no lower than level 8. The adjustable grind range is from 1, the finest, to 15, the coarsest. The number indicated by the grinder adjustment knob is the actual selected grind level. Adjust only one level at a time to avoid damaging the grinder.

While brewing coffee, press and hold the selected drink button for about 2 seconds. After you hear a beep and the corresponding indicator light starts flashing, the machine enters volume-setting mode. Release the button when the coffee in the cup reaches your desired amount. The machine will stop and save the new water volume. The adjustable range is 30-100 ml / 1.0-3.4 fl oz for single espresso, 30-100 ml x 2 for double espresso, and 110-180 ml / 3.7-6.1 fl oz for Americano.

When making a milk-based drink, press and hold the “Cappuccino” or “Latte” button for about 2 seconds. Release the button when the milk foam reaches your desired amount. The machine will stop and save the setting. This setting applies only to cappuccino and latte. The adjustable milk-frothing time is 10-40 seconds.

Press and hold the “Espresso” and “Double Espresso” buttons at the same time for about 2 seconds. The machine will restore all drink parameters to the factory default settings.

This is usually caused by the grind being too fine. Turn the grind setting one level coarser counterclockwise, then test again. If the flow is still very slow, the coffee outlet or powder chute may be clogged. First, gently clear the coffee outlet with a toothpick, then run the powder chute cleaning process.

First check whether the coffee outlet is blocked, and gently clear it with a toothpick if needed. If the machine grinds beans but no coffee comes out, dark oily beans or damp beans may have clogged the powder chute. Press and hold the “Bean-emptying” button and the “Espresso” button at the same time to enter powder chute cleaning mode. Use the cleaning brush to loosen built-up coffee grounds in the chute, then press the same button combination again to exit.

This is usually caused by a grind that is too coarse, or coffee beans that are not ideal for espresso extraction. Turn the grind setting one level finer clockwise and use beans suitable for espresso when possible. Adjust only one level at a time, then brew 1-2 cups to check the result.

The steam boiler may still be preheating. When the “Cappuccino”, “Latte”, “Hot water”, “Manual froth”, or “Manual clean” indicator lights are flashing, those functions cannot be used. Please wait until the corresponding indicator light stays solid before pressing the button.

Check the following in order: make sure the power plug is firmly connected, the outlet has power, and the On/Off power switch on the back of the machine is turned on. Then press and hold the power button on the control panel to start the machine. If the machine still will not turn on, please contact customer support.

If there is no operation for about 28 minutes in standby mode, the machine will automatically enter sleep mode. All indicator lights will turn off and the functions will pause. To use the machine again, press and hold the power button for about 0.8 seconds. The machine will run a self-check, preheat, automatically clean, and then return to standby mode.

Use refrigerated milk at 5-10°C / 41-50°F with at least 3% protein content. If the foam is still too thin or does not form, remove and clean the milk frother and milk tube. Make sure the air inlet is not blocked by dried milk residue.

This is usually related to milk that is too warm, milk that does not froth well, or a dirty/blocked milk frother. Use milk at 5-10°C / 41-50°F with at least 3% protein content, and remove the milk frother to clean the small holes. When reinstalling, make sure the side with the plug faces left.

You can reset the milk output amount. While making cappuccino or latte, press and hold the corresponding drink button for about 2 seconds. Release the button when the milk foam reaches your desired amount to save the setting. The adjustable milk-frothing time is 10-40 seconds.

Yes, we recommend cleaning it after every milk-frothing use. Remove the connecting tube, milk carafe, and milk frother, rinse them with clean water, and let them air dry. This helps prevent dried milk residue from blocking the air inlet or milk frothing channel, which can affect frothing next time.

This means the brew unit needs to be cleaned. With the machine powered on, remove the brew unit and rinse it with clean water. Let it dry, then reinstall it. After reinstalling, wait about 2 seconds; the indicator light should turn off. If it remains on, please contact customer support.

With the machine powered on, remove the grounds container and internal drip tray. Empty the coffee grounds and wastewater, then clean the parts. After cleaning, wait at least 3 seconds before reinstalling them so the machine can reset the counter and turn off the indicator light.

This is usually because the counter did not reset. Always clean the grounds container and brew unit while the machine is powered on. After removing and cleaning the parts, wait about 3 seconds before reinstalling them. If the grounds container is cleaned while the machine is powered off, the machine may not recognize it and may continue showing the reminder.

Remove the coffee outlet cover, pull out the milk frother, and rinse it with clean water. Use the included cleaning brush to clear the small holes if needed. When reinstalling, make sure the side with the plug faces left, then reattach the coffee outlet cover.

No. The manual states that removable parts such as the brew unit, water tank, milk carafe, drip tray, drip plate, internal drip tray, grounds container, and door must not be cleaned in a dishwasher. Clean them with clean water and a soft cloth or cleaning brush.

Run the descaling program. Add water and a household descaler to the water tank up to the MAX line. For household descaler, the recommended mixture is water to descaler = 4:1. If using citric acid, follow the final confirmed manual or engineering-approved ratio to avoid an overly concentrated solution. Place a container under the outlet, then press and hold “Hot Water” + “Manual Clean/Automatic Clean” at the same time for about 1 second to start descaling. The program takes about 10 minutes. When it is complete, the reminder lights will turn off.

The machine will display a descaling reminder after about 500 brewing cycles. We recommend following the machine reminder. If your local water is hard, or if you notice slower water flow or unusual temperature performance, check whether descaling is needed sooner.

With the machine powered on, press and hold “Manual Clean/Automatic Clean” + “Double Espresso” at the same time for about 1 second. The machine will enter the brew system deep-cleaning mode and move the brew unit to the bottom position. Open the door and clean the hard-to-reach areas. After cleaning, close the door and press and hold the same two buttons again for about 1 second to exit.

Method 1: Press and hold the “Bean-emptying” button + “Single Espresso” button at the same time until the corresponding indicator lights flash and the door opens. Use the cleaning brush to loosen built-up coffee grounds in the powder chute. After the grounds fall down, close the door. Press and hold the same two buttons again until the indicator lights turn off and the door closes. Method 2: When only a small amount of beans remains in the bean hopper, press and hold the “Bean-emptying” button to let the machine clear remaining powder from the chute. We recommend cleaning the chute once a week.

Add clean water to the water tank, and add clean water to the milk carafe instead of milk. Install the milk carafe and milk tube properly. In standby mode, press and hold the “Manual Clean/Automatic Clean” button. The machine will rinse the brew system and milk frothing channel. If you do not need to clean the milk frothing channel, make sure the milk frother plug is installed in place.

The water tank is low on water. Add water to the tank and reinstall it correctly. If the indicator still flashes after refilling, check whether the water tank is fully seated. If the issue continues, contact customer support.

This means the brew unit or internal drip tray may not be installed correctly. Reinstall the brew unit, push it all the way in until you hear a click, and make sure the arrows are aligned. Also check that the internal drip tray is sitting flat. If the light remains solid, please contact customer support.

This means the grinder knob, door, or internal drip tray may not be installed correctly. Reinstall the grinder knob, make sure the door is fully closed, and confirm that the internal drip tray is flat with no obstruction in front of it. If the light continues flashing, please contact customer support.

There are not enough coffee beans in the bean hopper. Add coffee beans and run one coffee-making cycle. The no-bean reminder will clear automatically.

This indicates an abnormal grinder motor operation. Turn the machine off and restart it. If the two lights continue flashing after restart, please contact customer support.

This means the machine has ground beans too many times in a row, and the system has entered forced cooling protection. All functions will be temporarily paused. Wait about 5 minutes, or turn the machine off and restart it. If this happens repeatedly, please contact customer support.

This indicates that the flow meter has no signal or that water output is abnormal. First check whether the water tank has water and is correctly installed. If the lights continue flashing after refilling, please contact customer support.

This indicates no signal from the Hall sensor or an abnormal brew motor condition. Turn the machine off and restart it. If the lights continue flashing after restart, please contact customer support.

Some operating noise during grinding and brewing is normal. If the sound suddenly becomes noticeably abnormal, or if you hear sharp rubbing, scraping, or unusual noises, stop using the machine. Clean the removable grinder components according to the manual. If the noise continues, please contact customer support. We do not recommend disassembling the machine yourself.

The machine may not have been shut down correctly, so the brew unit did not return to its home position. Turn the machine off and then back on, allowing the brew unit to reset automatically before trying to remove it again. If it still cannot be removed, there may be a blockage or component issue. Please contact customer support.

The powder chute may be clogged. Common causes include dark-roast oily beans with too much surface oil, or damp coffee beans. Follow the powder chute cleaning instructions above, and avoid continuing to use beans that are heavily oily or damp.

First make sure the machine has finished preheating and the corresponding function indicator light is solid before brewing. We also recommend preheating your cup with hot water. If the descaling reminder is showing, if your local water is hard, or if the water flow has slowed, run the descaling process. If the temperature is still abnormal after descaling, please contact customer support.

Wipe the exterior with a soft, damp cloth. Do not use alcohol, solvents, steel wool, or abrasive cleaning tools, as they may scratch or damage the surface.

This model does not include a separate grounds-and-water separation system. Some wet grounds, loose grounds, and water in the drip tray can be normal and does not necessarily indicate a malfunction.

This can vary depending on the type and roast level of the coffee beans. If the grounds are loose and there is more water in the grounds container, the grind may be too fine. Try setting the grind one level coarser. This automatic coffee machine uses a horizontal compression extraction structure. Because a small amount of liquid can remain after horizontal extraction, and the puck is pushed out automatically after brewing, it is normal for some grounds to be loose or not fully puck-shaped.

For first use, start around levels 8-10. Then fine-tune gradually based on taste: if the coffee tastes too sour, adjust finer; if it tastes too bitter, adjust coarser. When switching to a new type of beans, we recommend clearing the remaining beans first, then selecting an appropriate grind level based on the roast level of the new beans. Adjust only one level at a time to avoid damage.

Yes. For seasonal fine-tuning: in colder winter conditions, light-roast beans may need to be adjusted one level finer, for example from 4 to 3, to compensate for under-extraction caused by lower temperatures. In humid summer conditions, dark-roast beans may need to be adjusted one level coarser, for example from 11 to 12, to help prevent moisture from causing grounds to clump and slow the flow. For blended beans: for a light + medium roast blend, start around level 7. If the acidity is too strong, move one level toward the darker-roast side. For a medium + dark roast blend, start around level 9, and increase the coffee amount by about 1 g if you want a fuller body.

Yes. You can freely adjust the coffee strength and milk ratio. While coffee or milk is dispensing, press and hold the drink button for 2 seconds. After you hear a beep and the corresponding drink icon starts flashing, release the button when the desired amount is reached. After the drink cycle finishes, the coffee and milk volume settings will be saved. Espresso volume range: 30-100 ml / 1.0-3.4 fl oz. Double coffee volume range: 30-100 ml x 2. Americano volume range: 110-180 ml / 3.7-6.1 fl oz. Milk dispensing range: 10-40 seconds.

Coffee strength is affected by the beans, grind size, and extraction time. You can adjust the grind size and extraction time to better match your taste. This coffee machine cannot directly adjust the coffee-to-water ratio, so we recommend improving the result by changing the grind setting or choosing a different type of coffee beans.

The bean-emptying function is designed to require a press-and-hold action for more than 1 second to help prevent accidental operation and wasted beans. Other buttons are short-press buttons. Wet fingers or moisture on the control panel may affect short-press response. Wipe the panel and your hands dry, then try again.

This is the descaling reminder. When the hot water function and manual cleaning function indicator lights flash at the same time, the machine needs to be descaled, usually after about 500 cups of coffee. Descaling method: 1. Add water and household descaler to the water tank at a water-to-descaler ratio of 4:1. Do not exceed the MAX line. Citric acid may also be used instead of descaler at a water-to-citric-acid ratio of 100:3. 2. Place a cup on the cup tray. Press the hot water function and manual cleaning function buttons for 1 second to enter the descaling process. 3. The descaling program lasts about 10 minutes. The descaling indicator will remain on, and the 8 function indicators will slowly flash from left to right. 4. After descaling is complete, the flashing hot water and manual cleaning indicators will turn off.

Automatic cleaning: When the machine is powered on from off, standby, or sleep mode after being idle for more than 28 minutes, it will enter automatic cleaning. This rinses small amounts of coffee and milk residue from the internal lines so the next coffee or milk drink tastes fresh. Manual cleaning: If the machine is used continuously, or if users have different taste preferences, you can manually select cleaning between drinks.

Recheck the installation of these four parts: the grinder knob, brew door, brew unit, and the right-side drip tray/grounds tray. Once they are correctly installed, the warning icon should disappear and the machine should resume operation.

The heating module is located in the lower-left area of the machine and includes two independent heating cores: one instant-heating system for coffee extraction and one steam heating system, or boiler, for milk frothing. During operation, the system can heat room-temperature water to 86-96°C / 187-205°F in a short time, so some residual warmth around the heating area is normal. The residual surface temperature remains below 60°C / 140°F. For safety, the machine is equipped with multiple temperature-control protections, including an NTC temperature sensor, thermostat, and thermal fuse. These safety systems help control temperature, prevent overheating, and support safe household use. The product has passed strict safety testing and meets household-use standards.
