With the bulk of the modules spread across our teardown table, the remaining guts are just a few hoses and pipes. We've earned a cup of coffee and the Impressa A9 has earned a repairability score of 7 out of 10 (10 is the easiest to repair):

The coffee maker is built with modular components that can be maintained separately. All screws inside are standard Torx.

There are no adhesives or one-way-clips used inside the machine. However the side panels with their glass front and tiny, invisible hooks are a major drag (even authorized technicians might struggle at this point).

The oval head screw behind the logo plate is one proprietary screw too many. The sole purpose of it is to keep you out.

There is no official documentation for repairs of internal components.
