I was looking for instructions for a Bialetti Mukka Express ;and also does this unit make espresso?

Easy!! Not making coffee or cappuccino, go to Starbucks less issues LOL

If the bottom is screwed too tight on the top, you could try to warm the with hot water and cool the bottom with cold. This could help to expand the top and make it easier to unscrew.

Try turning down the temperature. Also make sure there is no coffee left around the edge of the joining surface. This worked for me.

There is a line inside the water compartment, look for the rectangles that go from the bottom up in the walls, there is a line above them... that is the level for gas stoves, for electric ones just put a little more.

dip the top part upside down in warm water, make sure the bottom doesnt warm up, the material from the top will expand and comes loose from the bottom, it might need powerfull hands anyway good look

First off, the best milk for foam is skim milk (0% fat). The higher the fat content, the less foamy your foam will be.

The foam is created by the steam/hot coffee from the lower part being forced through the doohickey and into the milk. That means that if the coffee itself isn't "perfect", the foam won't be "perfect". I've found that using different types of coffee (e.g. different grinds) or filling the coffee bin to different levels results in more or less steam/pressure being passed through, so the foam is better/worse. For example, if I put too much ground coffee in the bin or use too fine a grind, it blocks the water/steam that's going through the coffee, resulting in less coffee and weaker coffee, and also resulting in less foam.

could it be that the gasket is oversized and it covers the small holes ?

put some drops of machine oil at the point the two parts join and srew it and unscrew it four times. then you make coffee again!

it did that to me too, so I reduced the amount of milk to the indicated level inside. No more mess after that.

HAVE YOU TRIED SYDNEY?
