How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines push water through the coffee grounds with pressure. This method of brewing creates more flavor than drip coffee. The machines require nine bars of pressure to extract the flavor from the ground.
Espresso machines are available in three major kinds. They include manual, semiautomatic and fully automatic. Semiautomatic machines allow you to control grinding, tamping and extraction time. They are a good compromise between machine control and human reliability.
Simple to use
The top espresso machines come with an easy-to-use interface. They have an adjustable thermostat that maintains water at the ideal temperature and a pressure pump that increases the amount of water used per shot. The higher pressure helps the grounds dissolve faster and creates a crema with the right consistency. They also have an milk frother that can make espresso-based drinks like lattes and cappuccinos.
The steam-driven machines of the past use an airtight tank to heat water until it is boiling point, and then release the pressure into a shot espresso. While they're inexpensive and compact they're able to only deliver only 1-2 bars of pressure which is less than the ideal 9 bars for espresso.
Semi-automatic espresso machines pump hot water into a portafilter stuffed with beans that have been ground and pretamped. The barista is responsible for the extraction process but has to manually measure grind, grind and tamp every cup of beans. While this style of machine is more expensive than others it offers greater control and stability, says Jai of Blank Street Cafe.

Most come with built-in grinders which click into the portafilter. They automatically grind and dose the beans, and can be adjusted to make various drinks. Some even have a milk hopper and can create froths and pours milk for you.
Easy to clean
Espresso machines use higher pressure and heat than drip coffee makers to make an extremely full-bodied and thick shot.
