Safety first: Follow Tassimo's official descaling instructions and use approved descaling tablets.

• Prepare solution: Fill the water tank with fresh water and dissolve the recommended Tassimo descaling tablets.
• Insert service T DISC: Place the yellow/orange service disc in the brew head with the barcode facing down.
• Run descaling program: Start the descaling cycle and allow it to run to completion without interruption.
• Rinse thoroughly: After descaling, rinse the tank and run multiple rinse cycles with clean water to remove any remaining solution.
• Reset indicator: The descaling light should turn off automatically after a complete cycle. If it does not, repeat the cycle once more.
