How to Clean Coffee Machine Espresso
Regardless of whether you're a home barista or a professional, your espresso machine needs to be cleaned regularly. If not cleaned regularly, the buildup of oils and milk proteins can cause a decrease in espresso quality.
Fortunately, cleaning is fairly simple. To get started, you only need a few basic items with commercial coffee machine.
Cleaning the Group Head
The group head, which is usually located at the front of the espresso machine's espresso machine, is responsible for separating water and coffee grounds and controlling temperature and pressure. It is essential for making high quality espresso and must be cleaned regularly.
Back-flushing: This is done by running a blind filter in the group head, using a cleaning solution (usually Urnex Cleancaf) to flush out old oils and bacteria from within the group head and solenoid valves. It helps prevent coffee oil build-up in the solenoid, ensuring smooth operation of the machine and great espresso.
Cleaning the Group Head Gasket: This small seal is between the group head & portafilter and must be cleaned every day to maintain a positive seal. Use a specially designed group cleaning brush and hot water for vigorously cleaning the sealing surface.
Shower screens: They must be replaced every so often. However, they can be cleaned more easily by being removed from the group head and soaked in hot water and espresso machine cleaner for 10-15 mins. Then scrubbed with a brush.

Cleaning the filter screen
As a more concentrated form of coffee, espresso gives fans a bracing shot of flavor and caffeine. Espresso machines are more complicated than standard coffee makers. They have more parts that collect oils and residue, and sometimes get dirty.
If you want your espresso machine to last a long time with commercial bean to cup coffee machine and produce consistent, great-tasting coffee, you need to clean it on a regular basis. This is because coffee, milk and tap water create a lot of debris that can block parts of the machine.
One of the first places that debris can collect is in the filter screen (also known as the group screen). It's easy to keep your filter screens clean and functioning well. Remove the filter screen and scrub both sides with a nylon brush or scrubby pad to get rid of any buildup. Rinse with a lot of water to ensure that you have cleaned every trace of detergent from the screen.
Steam Wand Cleaning
The Steam Wand is an integrated feature on most manual and semi-automatic espresso machines that enables you to create everything from lattes to macchiatos. It releases steam to foam the milk and give your drink a creamy texture.
After using a Steam Wand, it should be wiped clean to prevent buildup of milk that can cause it to become blocked or fail to work properly. Purging the Steam Wand is also essential to ensure that it doesn't clog, which can happen when there's too much water or a buildup of solids in the wand.
To purge a steam wand, simply turn off the machine such as coffee machine bean to cup and wait for no water to flow through it. This helps the wand to cool down and evaporate, flushing any residue from the inside out and keeping it functioning efficiently for longer.

Cleaning the Drip Tray
The drip tray, or cup-like container that catches water that's flushed out of the machine, needs to be cleaned periodically. This keeps your machine free of coffee and milk residue with coffee machine.
The best way to clean your drip tray is to use a lint-free cloth and a bit of warm water. Some machines have an indicator that lets you know when it's time to wash the drip tray.
In addition to catching spilled espresso, the drip tray also collects residue from grounds that are left in the portafilter basket. These can cause problems during the brewing process, making your espresso taste less fresh.
The type of water you use and the machine you have will determine how much cleaning you need. Typically, decalcifying your machine every three to four months if used regularly and more frequently with hard water is recommended.
