Sound and Vibration
Q1: Does the Mijia Portable Coffee Machine make noise during operation?
A: The Mijia Portable Coffee Machine produces slight noise during operation. The internal high-pressure electromagnetic pump vibrates rapidly during operation, producing sound. Some table surfaces may amplify the working sound caused by vibration. Ensure the coffee machine is placed on a stable surface. In addition, some capsules are filled with densely packed coffee grounds, and the bursting at the beginning of production is slow. At this time, the extraction pressure is high, and the load on the water pump is high, so the sound may seem louder. This is a normal phenomenon.
 
Q2: Why is there a "pop" sound during coffee extraction with the Mijia Portable Coffee Machine?
A: During coffee extraction, the high-pressure 20 Bar water pump injects high-pressure hot water into the coffee capsule and mixes it with the coffee grounds. After the coffee liquid is extracted to a certain concentration, the front aluminum foil is burst, producing a "pop" sound. This is a normal phenomenon.
 
Q3: Why is the extraction sound sometimes loud and sometimes quiet with the Mijia Portable Coffee Machine?
A: When using the grounds basket, the amount of coffee grounds loaded varies. Different brands of coffee capsules have different coffee ground coarseness and amounts, which can lead to different extraction pressures and inconsistent water pump sounds. When the pressure is too high, the extraction sound will be louder. This is a normal phenomenon.
 
Q4: Why does the sound and vibration of the Mijia Portable Coffee Machine sometimes become loud and sometimes quiet?
A: When the water pump pressure increases during extraction with the Mijia Portable Coffee Machine, the overall sound and vibration of the machine also increase.
 
Odors
Q1: Why does the Mijia Portable Coffee Machine have an odor when first opened?
A: After the portable coffee machine is produced, it is directly sealed in packaging. The packaging and foam are all new. After packaging and sealing, the coffee machine is in a sealed state, which may prevent odors from dissipating. This is a normal phenomenon. It is recommended to leave the coffee machine in the open for a few minutes, and the odor will quickly disappear.
 
Q2: Why does the coffee made with the Mijia Portable Coffee Machine have a burnt taste?
A: If the coffee beans are spoiled or roasted too dark, a burnt taste is easily produced during extraction.

Q3: How often should the Mijia Portable Coffee Machine be cleaned?
A: The Mijia Portable Coffee Machine needs to be cleaned after each use, especially the capsule chamber. The used coffee capsule should be removed and discarded to prevent mold growth during long-term storage.
 
Q4: Why should the metal grounds basket be allowed to cool before cleaning on the Mijia Portable Coffee Machine?
A: After the metal grounds basket has undergone hot water extraction at 92 °C, the stainless steel surface retains a large amount of heat and residual water. If it is opened immediately after extraction is complete, the surface temperature of the metal grounds basket is high and may cause burns. It should be allowed to cool for a period of time after extraction before cleaning.
 
Q5: Why is it difficult to clean the coffee grounds after using the grounds basket with the Mijia Portable Coffee Machine?
A: After extraction is complete, the coffee grounds in the grounds basket clump together, and the coffee puck is too wet, too dense, and adheres excessively to the water distribution mesh or grounds basket. At this point, when the grounds basket is inverted, the coffee grounds will not automatically fall out. The handle of the scoop can be used to pry out the coffee grounds, and then water can be used for cleaning.
 
Q6: Why is the coffee extracted with ground coffee from the Mijia Portable Coffee Machine low in concentration?
A: The coarseness of different coffee grounds varies. When coarse coffee grounds are used, the extraction pressure inside the brewing assembly is low, resulting in poor extraction. When a small amount of coffee grounds is filled, the extraction pressure inside the brewing assembly is also low, resulting in poor extraction.
 
Q7: How to maintain and care for the Mijia Portable Coffee Machine?
A: After each coffee preparation, remove the brewing chamber seat, rinse it with clean water, let it air dry, and then reinstall it. After the brewing chamber assembly is removed, do not rinse the main unit.
