The Boiler or Thermoblock
The boiler is the mettle of the machine. It is creditworthy for heating the water to the optimal descent temperature, typically between 195°F and 205°F (90°C - 96°C). High-end machine much sport dual boilers: one dedicated to brewing espresso and another specifically for give steam to effervesce milk.
The Group Head
The group mind is the interface where the portafilter locks into the machine. It is the component through which pressurized hot h2o is present to the java grounds. Many professional-grade machines have an "E61 group head," known for its caloric constancy and pre-infusion capabilities.
The Pump
Espresso expect some 9 barroom of pressing to emulsify the coffee inunct right. The heart is the mechanical pump that furnish this force. Most dwelling machine use either a vibration heart or a quieter, more consistent circular ticker.

|---|---|---|
| Group Gasket | Make a stamp between the portafilter and grouping head. | Replace every 6-12 month |
