The espresso machine spins to steam but doesn't produce steam and the alarm lights come on What's going on?

The espresso machine rotates to steam but there is no steam and the alarm light is on.

Coffee comes out of the water in the form of a drop, not a stream.

After the purchase of the automatic coffee machine, the first few times of use are normal, but after several times of use, the above problems will occur, and check the thickness of the coffee powder is also normal. At this time, it is necessary to check whether there are two pieces of metal filter on the extractor. If there are two pieces, remove one piece, and the fault will disappear.

Can be solved in the following ways: after turning off (or before turning on), wrap the nozzle with a towel, which is mainly to prevent skid and protect the nozzle from scratching the surface of the tool, then clamp it with pliers, move the rotating pliers to remove the nozzle, and use a fine needle and cotton stick to clear the spray eyes and remove the dirt, so that you can easily clean the nozzle or nozzle. In addition, if it is really inconvenient to remove the nozzle, you can also use the detergent for the coffee machine to dissolve it with twice as much water, fill it in a small cup, place it on the shelf, and then rotate the nozzle into a small cup to soak for 30 minutes, so as to make the scale crisp and soft. it is easier to clean with a fine needle and a clean cloth. After cleaning up, start up and run, turn on the steam to the maximum, and spray out the small residual dirt.

Milking technique: tumbling vs rotation from a technical point of view, tumbling is relatively difficult than rotation! The effect is really better, I also use rotation to get rid of! My operation process is to turn on the steam to the strength I need at one time! In the first 3 seconds, I deliberately let the steam head float to the surface of the milk and made a "bared" sound. By doing so, I could "bake" the height of the foam I wanted, and it was easier to bubble! At the same time, the liquid level rotates easily, and then put the steam head down! Some TX would say, is it not all a big bubble? Try more and you can find the skill, and you can also control the amount of milk foam you want. The big bubble will be a little bit, but in the process after that, it will burst with the rotation of the milk! (after starting to spin, there will be no more "foam", so it is difficult to eliminate the thicker bubbles.) the premise for me to turn off the steam is that when the temperature of the milk reaches about 70 degrees, the surface of the rotating foam should have glossiness (the glossiness is proportional to the fineness of the foam)! If you lose the gloss, it means there is a hard layer of milk foam on it, or the temperature is too high! Raise the height, raise the temperature, keep the gloss! It's my whole process.
