Simple judgement of Grinding thickness of Coffee Powder

If the coffee liquid is light and the pressed powder is not shaped, it is loose and damp, and the powder is too coarse.

If the coffee liquid is very black, dripping, not in a straight line, and there is little liquid coming out for a long time, the powder is too fine.

Normally, at first, the coffee liquid is very strong, the liquid is in a straight line, and slowly fades. Pressed powder molding is not loose and not damp.

The machine used is the newly bought Delong ESAM 3200S. When using coffee powder to extract Espresso, it will press the powder automatically, but the flow rate of the coffee is uneven. When you are halfway through the extraction, you can stop for almost a second. You can hear a sound from the machine, and then you can continue to extract it, but it is not coherent. What's going on? Is it because this is a new machine that I have just tried two cups of coffee and have to make five or six cups to be normal?

The warning light is always on and the machine does not work after the Delon 3000 gamble 4000 series coffee machine is turned on.

5 Delong coffee machine 3500 6600, after being turned on, there is no Ready message for a long time, and finally GENERICALARM appears.

Check if there is heat in the warm cup area.

Usually the heater doesn't work, check the temperature protector.
