Check boiler pressure is at 1.0 bar (needle on right hand side of gauge in red band).check machine is switched to to position 2 (element symbol) on on/off switch. Too much pressure will slow down the flow of water through the espresso, leading to under extraction.

This is why many find themselves wondering how many bars of pressure an espresso machine should use? On the other hand, if your espresso flows out too slowly, your taste might get bitter, and you may notice a burnt taste and smell in it.

Generally, it requires enough pressure in the pump to produce the power needed to push the water through the grounds fast. Since between 7 and 9 bars of water pressure is optimal, we can consider anything below 7 bar to be too low and anything over 9 bar to be too high.

Milk frothing is aerating the milk, creating a heavy and thick foam to be mixed with coffee. While brewing the pressure never reaches 9 bar.

Steam Pressure Is Low Or Slow:

The pressure in the water supply is called the ‘line pressure’. Sounds a little questionable but cool none the less. It starts at 0, then goes up to 2 bar when the pour begins and then only reaches about 4 bar by the end of the shot.
