Paper filters collapse or fold over, causing grounds in the coffee or overflow.

Safety: Wait for brewing to finish before opening the basket.

• Use correct filters: Use the Braun‑recommended filter size and shape (e.g., #4 cone).
• Rinse filter: Pre‑wet paper filters to help them adhere to the basket walls.
• Adjust grind: Use a medium grind to prevent slow flow and filter collapse.
• Clean basket: Ensure the outlet is not partially blocked, which can increase pressure.
