Tassimo Over-Extraction / Overheating

Coffee tastes burnt or excessively bitter.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Limescale on heater causing uneven heating, Incorrect T DISC type, Repeated brewing with same disc, Faulty temperature sensor

Safety first: Let the machine cool before maintenance.

Use fresh T DISCs: Never reuse a T DISC. Ensure you are using the correct disc for the beverage type.
Descale thoroughly: Run a full descaling cycle to remove limescale from the heater and restore proper temperature control.
Rinse cycle: Run 1–2 rinse cycles (without disc) before brewing to flush old coffee residues.
If taste remains burnt: The temperature sensor (NTC) may be reading incorrectly, causing overheating. This requires professional diagnosis and replacement.
