How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines use pressure to push water through coffee grounds. This method of brewing creates a stronger drink than drip coffee. These machines need 9 bars of pressure to extract flavor from the coffee grounds.
Espresso machines are available in three major types. They are semiautomatic, manual and fully automatic. Semiautomatic machines allow you to regulate the grinding, tamping, and extraction times. They are a good balance between human control and mechanised consistency.
Easy to use
The best espresso machines have an easy-to-use interface. They have an adjustable thermostat that maintains the temperature of the water at a suitable level and a pressure pump that increases the amount water used per shot. The higher pressure allows grounds to disintegrate faster and produces a crema with the perfect consistency. These machines also have a milk frother to make espresso-based drinks, such as 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, then releases the pressure into a shot of coffee. They are compact and cheap, but they only reach 1-2 bar of pressure. This is less than the ideal 9 bars for espresso.
Semi-automatic espresso machines work by infusing hot water into a pre-ground and pre-tamped portafilter of beans. The barista is in charge of the extraction process but must manually measure grind, grind and then tamp each cup of beans. While this style of machine is more expensive than other models however, it gives more control and stability, says Jai of Blank Street Cafe.
Full-automatic espresso makers are easier to use than semiautomatic machines because they don't require the barista's involvement in the brewing process. Many have built-in grinders that plug into the portafilter. They automatically grind and dose the beans and can be adjusted to make various drinks. Some machines come with an hopper for milk that can make frothy milk and pour it to you.
Easy to clean
Espresso machines make use of higher pressure and heat than drip coffee makers to produce the perfect, full-bodied, thick shot. They also have a milk-frothing system that allows you to make cappuccinos as well as lattes. As such, they require more regular maintenance than a drip machine which includes descalers and regular cleaning. Fortunately most espresso machines are easy to clean. Some of the models on our list have been specifically designed to make cleaning a breeze.
Most espresso machines come with an in-built portafilter that holds the grounds of coffee when brewing. Some models also have a group head, which is a set of parts that perform the actual extraction. To ensure that these parts are free of gunk and grit it is necessary to backflush your machine on a weekly basis. This entails cleaning and brushing the group head, then locking the portafilter, and then running the brew cycle several times. Many coffeehouses backflush their machines every day, but home users should only need to do it once per week.
It is best to use filtered or softened water, since it can reduce the accumulation of mineral and the requirement to descale. However it is important to keep in mind that a moderate amount of minerals is required to ensure proper extraction. Too much mineral will overwhelm the flavor. A lack of minerals can result in weak, salty coffee. A well-maintained machine will ensure that it continues to function properly and taste delicious for as long as you own it.
Easy to maintain
An espresso machine is an impressive piece of equipment that allows you to serve a diverse range of coffee drinks. However, unlike a typical carafe coffee maker, an espresso machine requires a higher level of temperature and pressure to give the desired results. In order to do this, it needs to be properly maintained and cleaned. Fortunately, you don't need to be an expert in order to keep your espresso machine in good working order.

Backflush your group using a water-espresso machine cleaner. You will also want to clean your screen, including the nooks and crevices with a nylon toothbrush or Coffeetool.
It's also important to wash the drip tray daily, as it collects the coffee waste from each brewing cycle. It can also become an ideal habitat for bacteria and mold, which can affect the flavor of your coffee. Additionally, you'll want to clean the exterior of your machine often to prevent milk and coffee residue from building up.
Consider using a milk system cleanser that is designed to cleanse all components that come in contact with milk. These products are sold at most supermarkets and are simple to use.
