Brewing Tutorial
1. Grind too coarse – Adjust to a finer grind.
2. Too little coffee – Increase the dose (after tamping, the grounds should be near the groove line of the filter basket).
3. Coffee not tamped – Distribute evenly and apply firm, even pressure.
4. Stale coffee beans/powder – Use fresh coffee within 1 week to 1 month for optimal extraction.

1.The potafilter is not tightened to the right position. Please tighten the portafilter completely to the right.
2.Too much coffee powder remaining on the edge of the portafilter screen. Please clean the coffee powder
3.The coffee powder is too much. Please do not over the groove line.
4.The seal ring is broken and needs to be replaced.
The portafilter is not installed in place or tightened completely, the high pressure of the extraction will pressure on it.Please turn the portafilter tightly to the right when installing.
1.The machine is preheating. The button lights flash indicates that the machine is preheating, lights stay on indicates that the preheating is complete.
2. Insufficient water or water tank not in place. Please refill or put tank in place.
3. Filter basket clogging. Remove the filter basket from the filter and clean the holes with a brush or needle.
4.Too much coffee powder in the filter. Please reduce the amount of powder.
5. Excessive tamping pressure. Please reduce pressure.
6. Coffee powder is too fine. Please use to a coarser grind.
1. Grind the coffee finer.
2. Use the right amount of grounds.
3. Apply more pressure when tamping.
4. Ensure the portafilter is securely locked.
5. Use fresh coffee beans.
1. Too much coffee grounds – Reduce the amount (after tamping, the grounds should be near the groove line of the filter basket).
2. Grind too fine – Use a slightly coarser grind.
3. Clogged filter basket – Remove the filter basket from the portafilter and clean the holes with a brush or pin.

1. New machine – Before first use, drain the group head and steam wand for a while. Make 2–3 shots (discard) to clean the internal system before making coffee.
2. Dirty machine or portafilter – Regularly clean the group head, portafilter, and filter basket. Descale the machine every three months (watch "Cleaning & Maintenance" video for details).
3. Stale or low-quality beans – Use fresh, high-quality coffee beans within 1 week to 1 month.
4. Under-extraction (fast flow causing sourness) – Use a finer grind, increase the coffee dose, and tamp evenly with firm pressure.
5. Low brewing temperature – Fully preheat the machine and ensure the proper brewing temperature settings.
Pre-infusion function is only for automactic mode (single cup/double cup), manual mode is not included.
Without sufficient preheating, using cold group head or cup will reduce the extraction temperature.
Follow the tips to increase brewing temperature
1. Sufficient machine preheating when all the buttons are on
2. Press any brewing button to warm the group head before extraction
3. Place the cup in the warm cup zone or heat the cup with
hot water in advance
4. Adjust the brewing temperature to higher in the touch screen(G3006/G3007L)
Hot water is heated in the boiler, flows out through the brew head, passes through the portafilter, and reaches the cup. During this process, a certain amount of reasonable heat loss occurs, which is normal. The extraction temperature we refer to is the temperature of the water inside the boiler.

Steaming Tutorial
1. The container is too big or the milk is too little – Use a smaller milk frothing pitcher or add more milk.
2. The temperature of the milk is too high – Please use refrigerated milk.
3. Use skim milk – Please use cold whole milk.
4. Steam wand nozzle clogged – Clean out deposits in the nozzle with a needle.
5. for model G3005E/G3005H/G3006: The steam button wasn't pressed. Press the steam button and wait for the indicator stops flashing.
1. Please make sure that the machine is fully preheated (i.e. after the buttons and display have stopped flashing and the temperature value has reached the preset temperature), otherwise there may be insufficient steam pressure due to insufficient boiler temperature.
2. After preheating, when using steam for the first time, please drain the condensate from the internal water circuit of the machine first, it may take about 30s to 1 minute, which is also affected by the ambient temperature; when the condensate turns into drier steam, it can be used normally.
3. Recommended using cold whole milk, 15 oz milk frothing pitcher and pour cold liquid to 1/2 cup
1. When brewing heating, this sound is the normal operating noise of the machine's internal vibration pump.
The vibration pump uses an electromagnetic coil to drive a piston, generating pressure to push water through the coffee grounds for extraction. This repetitive motion naturally produces some noise, which can be heard when brewing coffee or using steam. This is a normal part of the machine's operation.
2. When steming, it is normal to hear sounds when frothing milk. When the steam wand’s dual holes are near the liquid surface, you may hear an air-intake sound caused by the steam vortex. If submerged slightly deeper, it will produce a stirring and heating sound as steam pushes the liquid. However, if the steam wand is inserted too deep, the noise may become harsh. For optimal frothing, try keeping the wand about 1cm deep and adjust the angle to control air intake, which affects the foam thickness.
Compared to other espresso machines, Gemilai G3006 and G3007L features a longer steam wand, making it suitable for various frothing pitchers. Its stronger steam power allows for quicker and creamier milk frothing.
3. The clicking noise during heating is generally normal, the sound comes from the solenoid valve engaging during the heating process near the heating pot. The screws might be slightly tightened, making the sound more noticeable, but this does not affect normal use.

Use Tips
Follow the "Before First Use" steps in the manual.
1. Take out the machine and all accessories, and check against the manual to ensure nothing is missing.
2. Assemble the machine (if needed): install the water tank and drip tray, ensuring the water tank is securely in place.
3. Plug in the power (make sure it is fully inserted into the socket). Turn on the machine and wait for it to preheat. Once preheated, press the extraction button to clean the internal water path. After that, press the steam button and wait for it to preheat, then release steam for a while to clean the inside of the steam pipe.
4. After cleaning, make two cups of coffee and discard them (do not drink), to ensure there is no metallic taste from the new machine. After that, you can start making and enjoying coffee normally.
1) Guidelines for a standard cup of espresso (for reference only, the pressure rate and other statistics will vary depending on the roasting level, freshness, etc.)
• For single shot espresso, the amount of coffee powder is 9-12g, for double shot espresso, the amount of coffee powder is 17-20g.
• Water temperature: 194-205℉
• Group head pressure: 9-12 bar
• Extraction time: 25±5s
2) Select fresh coffee beans, generally roasted within three months of the date, to get a better, fresher taste;
3) Grinding the coffee powder in advance is not recommended. The taste is better with freshly prepared coffee powder, or else the carbon dioxide in the coffee powder will easily evaporate and absorb unnecessary odors;
4) If the coffee powder is too fine, it may cause excessive extraction, and if it is too coarse, it may cause insufficient extraction, so it should be adjusted to a proper fine grind;
5) Keep the remaining coffee beans sealed and well stored after use, and avoid placing them in humid environments or in direct sunlight.
1. Use fresh coffee beans – For the best flavor, use beans within 1 week to 1 month after roasting. Beans older than 3 months lose freshness as key compounds evaporate, reducing extraction quality.
2. Freshness impacts extraction – Fresher beans yield richer crema and more complex flavors due to higher extractable compounds.
3. Adjust grind size – Fresh beans require a coarser grind, while older beans lose compounds, leading to faster flow. To compensate, use a finer grind for aged beans.
1. Grind size, freshness, quantity of coffee powder, and tamping pressure.
2. Water temperature, pressure, and extraction time for the coffee.
3. Quality of the water used.
