What is a washer and what is it for

A washer is a simple yet important part used in a coffee machine to seal a joint, distribute pressure between components, or act as a separating element between metal parts. It can be found, for example, at screw connections, valves, hoses, or the water and steam inlet.

How to spot wear

A worn or damaged washer loses its shape or elasticity, which shows up as a loose joint, water or steam leakage, dripping, or unusual noise during coffee preparation. In some cases, a leak can also lead to a drop in pressure and reduced quality of the prepared beverage.

Why replace this part in time

A damaged washer can cause further damage to surrounding parts, as insufficient sealing increases the strain on the joint and nearby components. Timely replacement thus prevents bigger repairs and keeps the coffee machine running reliably.

How to choose the right washer

Washers differ in size, shape, and design depending on where they are used in a particular coffee machine. Before purchasing, check the compatibility directly in the product table to choose the washer matching your joint.
