Brew that runs but no longer tastes or volumes as it should

Coffee Machines
The coffee appliance in a Thermador run is built into the millwork. Water, brew, and grind happen behind a furniture door, not on a countertop drip tray.

Overview

Built-in coffee is plumbing plus a brew group behind a door that matches the rest of the run. Some machines add a grinder. Milk hardware is only relevant where that system is actually fitted — this page does not add it to every unit.
Water in, coffee out, waste into the cabinet: that path is the category. Cleaning cycles are part of how the machine keeps itself in spec; they are not a substitute for a visit when a leak or a dead grind is already present.
If the machine is already failing, Coffee Machine Repair is the service counterpart. Keep the cabinet dry and the unit off until that visit is booked.
Signs worth having checked
Water appearing in the cabinet rather than the drip path
A grinder that stays silent or will not start, where fitted
Cleaning or descaling cycles that will not complete
A display message tied to brew, water, or maintenance
Safety first Power the unit down if water is behind the furniture panel. A hidden leak is not a countertop drip. Do not keep brewing into a wet cabinet.
Frequently asked questions
A water path, a brew group, temperature control, cleaning cycles, and a grinder where the machine includes one. A milk system is only in play if that hardware is on the unit.
Water and waste lines, the cutout, and neighboring cabinets set how the chassis comes out. It is not a plug-in carafe.
The exact display text, whether the last action was brew, grind, or a cleaning cycle, and the model from the dataplate if it is visible.
When brew, leak, grind, or a repeating message is already happening. Coffee Machine Repair is that path.
