How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines make use of pressure to push water through coffee grounds. This method of brewing creates an even stronger drink than drip coffee. These machines require nine bar of pressure in order to extract the flavor from the ground.
There are three primary types of espresso machines. They are manual, semiautomatic and fully automated. Semiautomatic machines let you regulate grinding, tamping and extraction time. They offer a good compromise between human control and machine reliability.
espresso machines for home to use
The best espresso machines have an intuitive interface. They have an adjustable thermostat to keep the temperature of the water at a suitable level and a pressure pump that increases the amount of water used per shot. The increased pressure makes the grounds to dissolve faster and creates a whipped cream with the perfect consistency. The machines are equipped with a milk frother for making espresso-based drinks such as cappuccinos and lattes.
The traditional steam-driven electric machines make use of an airtight tank to warm water until it reaches boiling point, and then release the pressure into a shot espresso. They are compact and cheap but they can only deliver 1-2 bar of pressure. This is less than the ideal 9 bar needed for espresso.
Semi-automatic espresso machines function by infusing hot water into the portafilter, which is pre-ground and pre-tamped of beans. The barista is responsible for the extraction process but has to manually measure, grind and tamp each cup of beans. Although this kind of machine is more expensive than other machines however, it gives more control and stability, says Jai of Blank Street Cafe.
Full-automatic espresso machines eliminate the barista from the brewing process, making them more user-friendly than semi-automatic models. Most come with built-in grinders that connect to the portafilter. They automatically grind and dosing the beans, and can be adjusted to make different drinks. Some machines have an automatic milk hopper that can froth milk and pour it for you.
Easy to clean
Espresso machines use higher pressure levels and heat than drip coffee makers, resulting in an intense, full-bodied shot. They also have a milk-frothing system that allows you to make cappuccinos as well as lattes. They require more care than drip machines, and require regular cleaning and descale. Fortunately that most espresso machines are simple to clean. A few of the models on our list were designed to make this process easier.
Most espresso machines have a portafilter that holds the grounds of the coffee while it is the brewing. Some models also have a group head, which is a set of parts that perform the actual extraction. Backflushing your machine on a regular basis will keep these parts clean and free of gunk and grit. This means cleaning and brushing the portafilter, locking it and running the brew cycle multiple times. Backflushing is done daily in many coffeehouses, but at home it should only be done every other week.
The use of soft or filtered water is recommended as this can reduce the buildup of minerals and cut down on your need to descale. However it is crucial to note that a reasonable amount of minerals is necessary to ensure proper extraction. Too much can muddle the flavor, whereas too little could result in an unsavory and weak cup of coffee. Maintaining your machine will ensure that it will continue to function properly and taste great as long as you have it.
Easy to maintain
An espresso machine is an amazing piece of equipment which allows you to serve a wide range of coffee drinks. But unlike your average carafe coffee maker, an espresso machine requires a higher degree of pressure and temperature in order to produce the desired results. To achieve this, the machine has to be maintained and cleaned regularly. Fortunately, you don't need to be a professional to keep your espresso machine running smoothly.
You'll want to clean the gasket at least once a week. The coffee oils could accumulate and create bitter taste in the espresso. Backflush your group using a water-espresso machine cleaner solution. You'll also need to scrub the screen as well as the nooks and cranny with a nylon brush or Coffeetool.
It is also essential to wash the drip tray regularly because it is the place where you collect the coffee waste that is generated from each brewing cycle. This can become an ideal habitat for bacteria and mold which can affect the flavor of your coffee. It is also important to clean the exterior of your coffee maker regularly to avoid the build-up of milk residue and coffee.
Consider using a milk system cleanser which is designed to wash all components that come into contact with milk. These products can be found in most grocery stores. They are also easy to use.

A coffee maker or espresso maker is a great appliance to have in the home or office. But, as with any electrical appliance, it is likely to malfunction from time to time. This can be frustrating especially if your coffee or espresso machine stops working. Luckily, most of these issues can be easily fixed. In many cases, these issues result from a simple error or poor maintenance.
Make sure that the machine has been connected and functioning. Examine the water tank for clogs or obstructions. If the issue persists, it may be time to call a professional technician.
Espresso and coffee machines can encounter a myriad of issues such as no power and heating, damaged steam wands or inability produce enough pressure. Some of these problems are easy to fix, while others require a thorough troubleshooting or cleaning. These tasks must be completed with extreme caution and care because many parts can be fragile and damaged.
Consult a professional if you are unsure about how to repair your espresso or coffee machine to avoid costly repairs.
