What is a group lever knob

The group lever knob is the grip part of the lever used to control the opening and closing of the brew or steam group on a coffee machine. The barista holds it every time the lever is adjusted, so it is exposed to frequent mechanical stress as well as heat from the nearby group.

Signs of wear

Over time the knob may become loose, crack, or start spinning on the lever, making precise control difficult. A damaged or brittle surface can also feel unpleasant to handle, or the knob may break off completely, making the lever hard to operate.

When it's time for a replacement

A loose or damaged knob increases the risk of inaccurate lever control, which can affect the consistency of coffee preparation and, in extreme cases, lead to damage of the lever itself or the group. Timely replacement ensures comfortable and safe operation of the machine.

How to choose the right part

• Check compatibility with your specific model in the product table.
