Frequently Asked Questions

Why is my Tassimo machine not reading the capsule?

Capsule detection relies on a barcode or mechanical reader — dirt or a broken reader stops it. Error codes on Tassimo machines usually point to a specific condition: a full drip tray, an empty water tank, a stuck brew unit, or scale buildup. The most common codes are listed in our Not Reading Capsule guide — most are cleared by a power reset or a descaling cycle.

My Tassimo Tassimo T12 won't recognize the capsule — fix?

A code on the Tassimo display is the machine naming its own fault. Start with the easiest fixes: reseat the tank, empty the drip tray, and power-cycle the machine. If the code returns, our Not Reading Capsule guide lists the codes and their fixes.

How do I fix a Tassimo that doesn't detect capsules?

Most Tassimo error codes are warnings, not hardware failures. Check the drip tray, water tank, and brew unit first, then reset the machine. The common codes and their exact fixes are documented in our Not Reading Capsule guide.
