How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines make use of pressure to force water through coffee grounds. This type of brewing results in an even stronger drink than drip coffee. The machines require nine bars of pressure to extract the flavor from the ground.
There are three primary kinds of espresso machines. They are semiautomatic, manual and fully automated. Semiautomatic machines allow you to regulate the grinding, tamping and extraction time. They offer a good compromise between human control and machine reliability.
Simple to use
The best espresso machines have an intuitive interface. The top espresso machines have an adjustable thermostat that keeps the water at the correct temperature, and a pressure pump that increases the amount of water used in each shot. The higher pressure allows grounds to dissolve more quickly and creates a whipped cream of the perfect consistency. The machines are equipped with an milk frother to make espresso-based drinks like lattes and cappuccinos.
Traditional electric steam-driven espresso machines make use of an air-tight tank to heat the water until it reaches boiling point, and then release the pressure in a shot. They are compact and cheap however they only allow 1 or 2 bar of pressure. This is less than the ideal 9 bar needed for espresso.
Semi-automatic espresso machines function by introducing hot water through a pre-ground and pre-tamped portafilter of beans. The barista is in charge of the extraction process, but has to manually measure the amount of beans, grind and tamp each cup of beans. This machine is more expensive, but it is more reliable and stability. Jai from Blank Street Cafe says.
Full-automatic espresso makers are more simple to use than semiautomatic machines because they do not require barista's involvement in the brewing process. Many have built-in grinders that connect to the portafilter. They then automatically grind and dosing the beans, and are often adjusted to produce different drinks. Certain machines have an hopper for milk that can make frothy milk and pour it into your cup.
Easy to clean
Espresso machines use higher pressure and heat than drip coffee makers, resulting in an intense, full-bodied shot. They also have a milk-frothing system that lets you to make cappuccinos and lattes. They require more maintenance than drip machines, including routine cleaning and descale. The good news is that most espresso machines are simple to clean.

This involves cleaning and brushing the portafilter, locking it and running the brew cycle a number of times. Many coffeehouses backflush machine espresso their machines every day, but home users should only need to do it once a week.
Using filtered or soft water is suggested, as this will reduce mineral buildup and reduce the need to descale. It is essential to remember that a moderate amount is required to extract. Too much can muddle the taste, while too little can lead to the cup being weak and salty of coffee. A well-maintained machine will ensure that it will continue to function properly and taste delicious for the duration of time you have it.
Easy to maintain
A coffee maker allows you to prepare many different coffee drinks. A carafe-style maker can provide the same results however an espresso machine needs greater pressure and temperatures. In order to do this, it has to be properly maintained and cleaned. Fortunately, you don't need to be an expert to keep your espresso machine in good working order.
You'll want to clean your gasket every week. This is where the coffee oils build up and cause the bitter taste of rancid espresso. Backflush your group with a water-espresso machine cleaner.
