How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines force water through the coffee grounds by using pressure. This type of brewing produces more flavor than drip coffee. The machines require nine bars of pressure in order to extract the flavor from the ground.
Espresso machines are available in three primary kinds. They are manual, semiautomatic and fully automated. Semiautomatic machines allow you to control grinding, tamping and extraction time. They are a good balance between machine control and human reliability.
Easy to use
The best espresso machines are simple to use. The top espresso machines feature an adjustable thermostat that keeps the water at the right temperature and a pressure-pump which increases the amount of water in each shot. The higher pressure makes the grounds dissolve more quickly and produces a crema with the right consistency. These machines have an milk frother to make espresso-based drinks like capspuccinos and lattes.
Traditional espresso machines powered by steam make use of an air-tight tank to heat the water until it is at a boiling point, which releases the pressure into a shot of coffee. They are small and cost-effective, but they only reach only 1-2 bar of pressure. This is less than the ideal 9 bar needed for espresso.
Semi-automatic espresso machines work by introducing hot water through the portafilter, which is pre-ground and pre-tamped of beans. The barista handles the extraction process, but they must manually grind, measure, and then tamp down the beans prior to each cup. While this model is more expensive than other machines however, it gives more control and stability, according to Jai of Blank Street Cafe.
Full-automatic espresso makers are simpler to use than semiautomatic machines since they eliminate the barista's role in the brewing process. They usually come with grinders that connect to the portafilter. They automatically grind and dosing the beans and they can often be adjusted to produce different drinks. Some even include a milk hopper, and can make froth and pour milk for you.
Easy to clean
Espresso machines make use of greater pressure and heat than drip coffee makers to produce a thick, full-bodied shot. They also include a milk frothing system, which lets you make cappuccinos and lattes. This means that they require more frequent maintenance than drip machines which includes descalers and regular cleaning. Fortunately, espresso machines are simple to clean. Several models on our list have been designed to make cleaning easier.
Most espresso machines have a portafilter to hold the coffee grounds during brewing. Some models also have a group head that is a set that perform the actual extraction. To keep these parts free of grit and gunk, you'll need to clean your machine on a regular basis. This involves cleaning and brushing the portafilter, locking it and running the brew cycle multiple times. Many coffeehouses backflush the machines on a regular basis, but home users should only do it once a week.
The use of soft or filtered water is recommended, as this will reduce mineral buildup and reduce the need to descale. However it is important to keep in mind that a moderate amount of minerals are required to ensure proper extraction. Too much can overwhelm the flavor, while too little could result in an unsavory and weak cup of coffee. Maintaining your machine will ensure that it is working well and taste great for as long as you own.
Easy to maintain
An espresso machine is an impressive piece of equipment that enables you to serve a broad range of coffee drinks. However, unlike a typical carafe coffee maker, an espresso machine requires a higher amount of pressure and temperature to produce the desired results. To achieve this, the machine should be maintained and cleaned regularly. Fortunately, you don't need to be an expert in order to keep your espresso machine operating smoothly.
First, you'll need to thoroughly clean the group gasket each week. In this area, coffee oils can collect and cause bitterness in the espresso. To clean this up, backflush the group with a solution of water and espresso machine cleaner. You'll also want to scrub the group screen and the nooks and crannies with a nylon brush or Coffeetool.
It's also important to wash the drip tray every day because it collects coffee waste that is generated from each brewing cycle. This could be a breeding ground of bacteria and mold that could alter the taste of your coffee. Also, you'll need to clean the outside of your machine on a regular basis to prevent coffee and milk residue from accumulating.
You should consider using a milk system cleanser that is designed to cleanse all components that come into contact with milk. These products are sold in many grocery stores and are easy to use.

Coffee and espresso machines can encounter a myriad of issues, including no power or heating, defective steam wands, or inability to produce enough pressure.
