Used T DISCs are swollen, burst, or leaking grounds into the cup.

Safety first: Allow the disc to cool before handling; hot contents can cause burns.

• Clean outlet path: Remove and rinse the T DISC holder and outlet spout thoroughly.
• Clean piercing needles: Gently brush the needles to remove any lodged grounds.
• Check disc type: Ensure you are using the correct T DISC for your Tassimo model and not damaged or swollen discs.
• Test with different discs: Try a disc from another pack. If all discs swell, pressure control may be faulty.
• If problem persists: A technician should check the pressure sensor and safety valve.
