How to Properly Maintain and Clean an Espresso Coffee Machine Espresso machines use pressure to force water through coffee grounds. This type of brewing makes an even stronger drink than drip coffee. These machines require 9 bars of pressure to extract flavor from the grounds. There are three main types of espresso machines. There are three major kinds of espresso machines semiautomatic, manual and fully automated. Semiautomatic machines allow you to regulate the grinding, tamping, and extraction time. They provide a balance between human control and mechanised accuracy. Simple to use The best espresso machines are easy to use. The best espresso machines have an adjustable thermostat that keeps the water at a consistent temperature, and a pressure pump that increases the amount of water included in each shot. The higher pressure allows the grounds to dissolve faster and creates a foam of 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, and then release the pressure in a shot of coffee. Although they're compact and affordable, they can only reach the pressure of 1-2 bars, which is less than the ideal 9 bars needed for espresso. Semi-automatic espresso machines pump hot water into a portafilter stuffed with pre-ground and pretamped beans. The barista handles the extraction process but has to manually measure, grind and tamp each cup of beans. While this style of machine is more expensive than other machines but it gives greater control and stability, says Jai of Blank Street Cafe. Full-automatic espresso machines take out the barista from the brewing process, making them easier to use than semi-automatic models. The majority of them have built-in grinders which plug into the portafilter. They then automatically grind and dosing the beans and are often adjusted to make different drinks. Certain machines have a milk hopper that can foam milk and then pour it for you. Easy to clean Espresso machines utilize higher pressure and heat than drip coffee makers, resulting in the perfect, full-bodied, thick shot. They also come with a milk frothing system, which allows you to create cappuccinos and lattes. They require more care than drip machines, such as regular cleaning and descale. Fortunately most espresso machines are easy to clean. A few of the models that we have listed are designed to make this process simpler. Most espresso machines come with the portafilter, which stores the grounds of coffee during the brewing. Certain models come with a grouphead, which is a collection of parts that perform the extraction. To keep these parts free of grit and gunk, you'll need to flush your machine back on a weekly basis. This means washing and brushing the group head, and then locking the portafilter, and then running the brew cycle multiple times. Backflushing is routinely done in a lot of coffeehouses, however at home it should only be done once a week. Filtering or soft water is recommended, since this will help reduce the amount of mineral buildup and reduce your need to descale. However it is crucial to note that a moderate amount of minerals is essential to ensure proper extraction. Too much mineral can overwhelm the flavor. Insufficient amounts can result in an unsavory, salty coffee. Maintaining your machine will ensure that it is working well and taste great as long as you have it. Easy to maintain An espresso machine is an amazing piece of equipment that enables you to serve a diverse range of coffee drinks. A carafe-style coffee maker could produce the same results however, an espresso machine requires an increased pressure and temperature. To achieve this, the machine needs to be cleaned and maintained properly. Luckily, you don't have to be an expert in order to keep your espresso machine running smoothly. First, you'll need to thoroughly clean the group gasket every week. There, the coffee oils could accumulate and cause bitterness in the espresso. Backflush your group using water-espresso machine cleaner. It is also recommended to scrub the group's screen including the crevices and nooks using a nylon brush or Coffeetool. The drip tray is important to clean daily as it holds all the coffee waste from each brewing cycle. This can become an ideal habitat for bacteria and mold that could affect the taste of your coffee. In addition, you should clean the exterior of your machine often to prevent coffee and milk residue from accumulating. Think about using a milk system cleanser designed to clean all components that come in contact with milk. These products can be found in a majority of supermarkets. They are also easy to use. Repairable and easy to fix A coffee or espresso maker is a great appliance for home use or office. Like any other electrical appliance, it could malfunction at times.

If the issue continues then it's time to contact a professional technician. Coffee and espresso machines may encounter a myriad of issues such as no power, no heating, faulty steam wands, or inability to generate enough pressure. These issues are usually easily solved, but others require more extensive troubleshooting and cleaning. The tasks to be completed with extreme care and prudence, as many components are fragile and could be damaged easily.
