Delonghi Espresso Machine Not Flowing: Unclog It Like A Pro In 5 Easy Steps

Delonghi espresso machines are known for their reliability and quality, but even the best machines can experience problems from time to time. One common issue is that the espresso machine may stop flowing, preventing you from enjoying your favorite coffee drinks. If you’re facing this problem, don’t worry – there are several things you can do to troubleshoot and fix the issue.

Causes of Delonghi Espresso Machine Not Flowing

There are several reasons why your Delonghi espresso machine may not be flowing properly. Here are some of the most common causes:

• Clogged portafilter: The portafilter is the part of the espresso machine that holds the ground coffee. If the portafilter is clogged, it can prevent water from flowing through and making espresso.
• Dirty group head: The group head is the part of the espresso machine that dispenses the hot water. If the group head is dirty, it can clog and prevent water from flowing.
• Scale buildup: Scale is a mineral deposit that can build up inside the espresso machine over time. Scale can clog the water lines and prevent water from flowing.
• Defective pump: The pump is responsible for pushing water through the espresso machine. If the pump is defective, it may not be able to generate enough pressure to flow water.
• Air lock: An air lock is a pocket of air that can form inside the espresso machine. Air locks can prevent water from flowing properly.

If your Delonghi espresso machine is not flowing, there are several things you can do to troubleshoot and fix the problem. Here are some steps to follow:
