What is a lever group head

The lever group head is a mechanical part of the brewing unit through which water or steam flows into the portafilter. It works together with the lever mechanism operated manually by the user, ensuring proper sealing and pressure distribution during coffee preparation or milk frothing.

How to spot wear

A worn or damaged head shows up as water leaking around the portafilter, heavy or jerky lever movement, uneven pressure during extraction, and sometimes steam hissing outside its intended path. This results in inconsistent coffee taste and lower pressure in the cup.

Why you shouldn't put off the replacement

A damaged head also puts strain on other parts of the group, as improper sealing increases pressure losses and stresses the lever and sealing elements. Timely replacement prevents further faults and keeps brewing quality consistent.

Selection advice

When choosing a replacement, check the compatibility table on the product page to confirm the head matches your specific coffee machine model, since lever groups differ in construction between manufacturers and even device lines.
