How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines force water through the coffee grounds with pressure. This type of brewing creates more strength than drip coffee. The machines require 9 bars of pressure to extract flavor from the grounds.
There are three major types of espresso machines. They include manual, semiautomatic and fully automatic. Semiautomatic machines allow you to control the grinding, tamping and extraction time. They are a great balance between human control and machine reliability.
Simple to use
The best espresso machines have an intuitive interface. They have an adjustable thermostat that keeps the temperature of the water at a suitable level as well as a pressure pump which increases the amount of water per shot. The higher pressure helps the grounds dissolve faster and produces a creamy crema with the ideal consistency. These machines include a milk frother for making espresso-based drinks, such as lattes and cappuccinos.
The traditional steam-driven electric machines make use of an airtight tank to warm water until it reaches boiling point, and then release that pressure into a shot espresso. Although they're small and inexpensive they're only able to reach 1 or 2 bars of pressure, which is less than 9 bars required for espresso.
Semi-automatic espresso machines work by infusing hot water through the portafilter, which is pre-ground and pre-tamped of beans. The barista handles the extraction process but must manually measure grind, grind and tamp every cup of beans. Although this kind of machine is more expensive than other machines but it gives greater control and stability, according to Jai of Blank Street Cafe.
Full-automatic espresso makers are more simple to use than semi-automatic machines because they remove the barista's role in the making process. Most come with built-in grinders that are connected to the portafilter. They then automatically grind and dosing the beans and are often adjusted to produce different drinks. Some machines come with an automatic milk hopper that can make frothy milk and pour it for you.
Easy to clean
Espresso machines use higher pressure levels and heat than drip coffee makers to make the perfect, full-bodied, thick shot. They also include an automatic milk frothing device, that allows you to make cappuccinos and lattes. They require more care than drip machines, such as routine cleaning and descale. Fortunately, espresso machines are simple to clean. A number of models on our list have been made to make cleaning easier.

This involves rinsing and brushing the group head, and then locking the portafilter, and then running the brew cycle a few times. Many coffeehouses backflush their equipment daily however home users should only have to do it once per week.

Maintaining your machine will ensure it remains in good working order and taste delicious for as long as you have it.
