Valve drain for Nivona / Siemens coffee machines

What is a drainage valve and what is it for

The drainage valve is part of the coffee machine's brewing unit. Its role is to divert excess water away from the main flow path during coffee preparation and rinsing, ensuring correct pressure and system cleanliness during every brewing cycle.

How to spot wear

When the valve leaks or sticks, it can cause water leaking from the coffee machine, incorrect extraction pressure, changes in coffee taste, or error messages related to the brewing unit. Sometimes an unusual noise may occur when starting the brewing or cleaning program.

When it's time for a replacement

A damaged or worn valve can gradually damage surrounding parts of the brewing unit due to moisture or incorrect pressure. Timely replacement prevents major repairs and maintains consistent coffee quality.

How to choose the right part

Before purchasing, check compatibility with your coffee machine model in the product table, as the dimensions and shape of the valve vary between brewing units.
