Coffee brewing group spring

What is the brewing unit spring

The spring is a mechanical component of the brewing unit that provides the necessary pressure or return movement of the moving parts of the piston or cylinder during coffee preparation. Thanks to it, individual components return to the correct position and maintain the tightness and smooth operation of the whole mechanism.

Typical signs of wear

• The brewing unit moves more heavily or unevenly
• Unusual sounds occur during coffee preparation
• The piston or cylinder does not return to its original position
• Water or pressure leaks during extraction

When it's time for a replacement

A weakened or damaged spring disrupts the proper operation of the brewing unit, which can lead to uneven extraction, reduced coffee quality, or increased wear of surrounding parts. Timely replacement prevents more serious mechanism failures.

How to choose the right part

When choosing a spring, check compatibility with your coffee machine in the product table, as the dimensions and shape vary between models.
