Introduction
The gasket of the brewing unit has to withstand heavy usage. Especially the large O-Ring on the piston needs replacing from time to time. Follow this guide to replace the gasket.
Note: The images show the brewing unit of a Saeco Minuto and may may differ slightly, but the procedure is basically the same.
These instructions may also help with other Saeco models and with coffee makers from Philips and Gaggia—they are all made by the same manufacturer and have a very similar design.

On some models, the support valve is covered. In this case, you must unscrew the cover first.
