Quick Answer

To replace the sealing ring on your alfi insulated carafe, first identify the correct spare part for your model. Then, remove the old ring, clean the groove, and press the new alfi Dichtungsring into place. This simple fix restores a tight seal and prevents leaks.

Why Replace the Sealing Ring?

Over time, the sealing ring on your alfi insulated carafe can wear out, become brittle, or lose its shape. This is the most common cause of a carafe that no longer seals properly or leaks when pouring. Replacing the ring is a straightforward repair that extends the life of your carafe and keeps your drinks at the right temperature.

Choosing the Right Spare Part

alfi offers specific replacement sealing rings for different carafe models. For example, the alfi Dichtungsring Aroma Plus weiss (product ID 1668161) is designed for the Aroma Plus range. Always check your carafe model and the part's compatibility before ordering. If your carafe also needs a new insulating glass, consider a combined replacement part like the alfi Isolierglas mit Dichtungsring for the Amici or Nomos ranges.

Step-by-Step: Replacing the Sealing Ring

1. Identify Your Carafe Model: Check the bottom or side of your alfi carafe for the model name (e.g., Aroma Plus, Amici, Nomos). This ensures you order the correct replacement sealing ring. Common mistake: ordering a ring that looks similar but is not designed for your model. Always verify compatibility.
2. Remove the Old Sealing Ring: Carefully pull the old ring out of its groove. Use a blunt tool like a plastic spudger or your fingernail. Avoid scratching the carafe surface. If the ring is brittle, pieces may break off. Remove all fragments to ensure a clean surface for the new ring.
3. Clean the Groove: Wipe the groove with a damp cloth to remove any residue or debris. Let it dry completely before installing the new ring. Residue can prevent the new ring from seating properly, leading to leaks.
4. Install the New Sealing Ring: Press the new alfi Dichtungsring evenly into the groove. Start at one point and work your way around, ensuring it sits flat and is not twisted. Checkpoint: Run your finger around the ring to confirm it is fully seated. A twisted ring will not seal.
5. Test the Seal: Fill the carafe with water, close the lid, and tilt it gently over a sink. If no water leaks, the seal is correct. If you see a leak, remove the ring and reinstall it, checking for proper alignment.
