Espresso mechanics 101. Cleaning shower screen

i would like to share some top tips for keeping your coffee machine clean. Most people may know to backwash the machine. Use a blind filter and run the pump. That cleans the water paths through the group. But this is pointless if the shower screen is clogged and dirty. Backwashing will not clear hardened oils. Check under your group head and look at the screen. If it's looking blocked it will make a bad shot no matter what. It will unevenly distribute the water to one side or wherever it's not blocked and some of your basket will not be doing anything remaining unextracted. They are very simple to remove. Usually one bolt. And just replace them with a new one. They are cheap. There will be many machines out there that could benefit from this simple clean or replace item that will greatly improve your coffee. Below are some photos of a group head with the screen and dispersion disk removed. Clean both. Simple to remove one screw
