How to Properly Maintain and Clean an Espresso Coffee Machine
Espresso machines use pressure to force water through coffee grounds. This method of brewing creates more flavor than drip coffee. These machines require 9 bars of pressure to extract flavor from the coffee grounds.
There are three major types of espresso machines. There are three primary types of espresso machines semiautomatic, manual and fully automatic. Semiautomatic machines let you control the grinding, tamping and extraction times. They offer 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 a consistent temperature, and a pressure pump that increases the amount of water used in each shot. The increased pressure helps the grounds to dissolve more quickly and creates a crema with the right consistency. These machines have an milk frother to make espresso-based drinks like lattes and cappuccinos.
The traditional electric steam-driven machines make use of an airtight tank to warm water until it reaches boiling point, and then release the pressure to create a shot of espresso. They are small and affordable, but they only reach about 1-2 bars of pressure. This is less than the ideal 9 bars for espresso.
Semi-automatic espresso machines function by infusing hot water through the portafilter, which is pre-ground and pre-tamped of beans. The barista is in charge of the extraction process but has to manually measure, grind and tamp each cup of beans. This machine is more expensive, but it gives you more control and stability. Jai from Blank Street Cafe says.

They typically have integrated grinders that connect to the portafilter. They then automatically grind and dosing the beans, and can be adjusted to create different drinks. Some even have a milk hopper and can create froths and pours milk for you.
Easy to clean
Espresso machines use greater pressure and heat than drip coffee makers to produce a thick, full-bodied shot. They also come with the milk-frothing mechanism that allows you to make cappuccinos as well as lattes. In this way, they require more regular maintenance than a drip machine such as descale and routine cleaning. Fortunately, the majority of espresso machines are easy to clean. A number of models on our list were made to make cleaning easier.
The majority of espresso machines have portsafilters that hold the grounds of coffee while brewing. Some models have a grouphead that is a collection of pieces that do the extraction. Backflushing your machine regularly keeps these parts clean and free of grit and gunk. This involves cleaning and brushing the portafilter, locking it and running the brew cycle several times. Many coffeehouses backflush their machines daily, but home users should only do it once a week.
It is best to use softened or filtered water, as it reduces the accumulation of minerals and the requirement to descale. However it is important to keep in mind that a moderate amount of minerals are required for proper extraction. Too much mineral can ruin the flavor. Insufficient amounts can result in a weak, salty coffee. Maintaining your machine will ensure it will continue to function properly and taste fantastic for as long as you have it.
Easy to maintain
A coffee maker permits you to make various coffee drinks. But, unlike a standard carafe, an espresso machine requires a higher amount of pressure and temperature to give the desired results. To achieve this, the machine should be cleaned and maintained properly. Luckily, you don't have to be an expert to keep your espresso machine in good working order.
First, you'll need thoroughly clean the group gasket every week. This is where coffee oils gather and can cause the bitter taste of rancid espresso. Backflush your group using a water-espresso machine cleaner. You should also clean your screen including the nooks and crevices, with a nylon toothbrush or Coffeetool.
The drip tray is also essential to be cleaned regularly as it collects all the coffee waste from each brewing cycle. This could be a breeding ground of mold and bacteria that can alter the taste of your coffee. You'll also need to wash the exterior of your machine regularly to avoid the accumulation of milk residue and coffee.
It is also recommended to use a milk system cleaner, that is safe for food and designed to clean components that come in contact with milk. These products are readily available in the majority of grocery stores and are easy to use.

Coffee and espresso machines could be afflicted by a variety of issues that include no power and heating, damaged steam wands, or an inability to generate enough pressure.
