Over- Extraction
(Beyond Gray area)
The pressure gauge can help you detect whether the working pressure
is normal when extracting coffee.
The amount of coffee powder, the thickness of the grind, and the
strength of pressing the coffee are the factors that affect the pressure.
• Under-extraction
Under-extracted coffees taste sour or sharp.
If the coffee is ground too coarsely or the coffee is pressed too lightly,
the coffee capacity will increase, and the pointer will stay in the gray
front area, indicating under- extraction.
• Over- extraction
Over-extracted coffees taste bitter or astringent.
If the coffee is ground too finely or the coffee is pressed too firmly, the
coffee capacity will decrease, and the pointer will stay in the red rear
area, indicating over-extraction.
Important
I .The pressure gauge only displays the current working pressure status, whether the
pressure is low or high does not mean that there is a problem with the unit.
2.The pointer of the pressure gauge is only active when making coffee, and there is
no pressure indication when making hot water and steam.
3.When the pointer of the pressure gauge exceeds the pressure in the gray area, the
coffee machine can still work normally, there will be no potential danger, and you
can use it with confidence.
