Rancilio md lever spring 39220010

What is the grinder adjustment spring

The spring is part of the mechanism that holds the selected grind coarseness setting. It maintains pressure on the grinder's adjustment element so that the position doesn't shift on its own during operation once it's been set.

How to spot wear

When the spring loses its tension or breaks, the grind coarseness setting starts changing on its own. This shows up as inconsistent coffee taste, fluctuating brew strength, or mechanical clicking and loose movement of the grind control. In some cases, the adjustment ring or lever becomes completely loose and stops holding the selected position.

Why you shouldn't put off the replacement

A faulty spring causes the grinder to lose adjustment stability, leading to uneven grinding and poor coffee extraction. Prolonged use with a worn or damaged spring can also put extra strain on the surrounding plastic or metal parts of the mechanism.

Choosing the right part

Springs differ in shape, size, and stiffness depending on the specific type of grinder and coffee machine. Before ordering, check the compatibility table on the product page to make sure the part fits your machine's mechanism exactly.
