Capsules drip or spray coffee around the capsule holder instead of a clean stream.

Safety first: Allow the machine to cool and depressurize before opening the capsule chamber.

Steps:

• Clean piercing needles: Use a small brush and warm water to remove coffee residue from the top and bottom piercing needles.
• Inspect capsule seal: Check the rubber or silicone seal around the capsule chamber for cracks or deformation. Replace if worn.
• Check alignment: Ensure the capsule holder slides in smoothly and locks fully. Misalignment can prevent a proper seal.
