Coffee group piston guide

What is a brewing unit guide

The guide is a guiding element in the coffee machine's brewing unit that ensures precise and smooth movement of the mechanism's moving parts - piston, spring or cam. It keeps them on the correct path during every brewing cycle and prevents lateral slipping or sticking.

Signs of wear

• The brewing unit works more noisily or jerkily
• The mechanism gets stuck or fails to complete the full movement
• Increased friction causes faster wear of surrounding parts
• The coffee machine may display an error related to the brewing unit

When it's time for a replacement

A worn or damaged guide disrupts the precision of the entire brewing unit's movement, which can lead to uneven pressure during coffee preparation and increased wear of other mechanism components. Timely replacement protects the whole mechanism from greater damage.

Selection advice

Since guides differ in shape and size depending on the specific type of brewing unit, check compatibility in the product table before purchasing.
