I. Funnel Filter Separates + Cup Moves During Coffee Making + Temperature Not Hot Enough
Filter Separation:
There is a convex point on the filter. Snap the convex point of the filter into the groove of the portafilter and then rotate the filter out of the groove of the portafilter. Refer to the video link: https://www.youtube.com/watch?v=kX_CWnoMKPM&list=PLUHnoyWSbujYFxnRe2OrpC0TViKxiWZPS&index=1
Cup Movement:
When making coffee, the machine needs to pump water into the heater through the pump and extract coffee through pressure, so the pump will vibrate the machine and cause the cup to move. This is a normal phenomenon.
Temperature Issue:
Firstly, check if the pressure is in the blue area and it is normal. Secondly, if you want to increase the pressure on the coffee, consider the following factors:
-
Roast Degree of Coffee Beans: For making espresso, medium- or dark-roasted coffee beans are well-suited. If you use light-roasted coffee beans, the final coffee will be lighter in both its color and flavor.
-
Grind Size: To make good espresso, a fine grind is a must. Coarse coffee grinds can make the extraction too fast and lead to an under-extraction. But also note don’t use too fine grinds to avoid water blockage that causes overflow from the portafilter.
-
Grind Dose: Add a proper amount of coffee grinds to the portafilter, the dose of the single cup is around 7 grams, and the double cup is around 14 grams but does not over the MAX line.
-
Tamping Force: Tamp the coffee grinds firmly with pressure around 10 - 15kg but not too hard to avoid water blockage or overflow from the portafilter. After tamping, make sure to wipe away any excess coffee grinds on the edges of the portafilter before installing it on the machine.
-
Water Temperature: Before brewing, make sure the knob is in a horizontal position (off-position) and the temperature is suitable, at this point, the blue lights of the ON/OFF Button, Single/Short Cup Button, Double/Long Cup Button, and Steam Button will be solid on.
-
-
Low Temperature: The machine is just turned on and in the process of pre-heating, the 4 buttons start to blink blue light slowly, so it has not reached a suitable temperature for brewing coffee. Before brewing coffee, make sure the pre-heating process has finished.
-
High Temperature: The suitable temperature for brewing coffee is around 92 degrees Celsius (198 degrees Fahrenheit). If you accidentally press the Steam button or immediately brew coffee after steaming, the temperature will be too high, and it is not suitable for brewing coffee. If so, reset the Steam button to its initial state and wait until the temperature cools down to an appropriate temperature for coffee. There are two ways to cool down the machine:
-
Wait for the machine to lower down to a suitable temperature, but this will take some time.
-
Turning the knob to the hot water icon will pump cold water into the boiler, which will help cool the machine. Wait until the white light of the Steam button turns off, the blue lights of the ON/OFF Button, Single/Short Cup Button, and Double/Long Cup Button are solid on, then turn the knob back to the horizontal position (off-position). Now, the machine is ready for brewing coffee.

Cups: If for 2 shots with 1 cup, it is recommended that the capacity of the cup is about 100ML. While for 2 shots with 2 cups or 1 shot with 1 cup, it is recommended that each cup is about 50ML. The cups without pre-heating or too large will make the temperature of the espresso drop quickly, resulting in a poor flavor.
-
Shot Volume: Around 40mL per cup is recommended.
