Diagnosis
This symptom is common and usually harmless. In most cases, a targeted clean or a small change in usage fixes the problem in under ten minutes.
Recommended procedure
Unplug the device, let it cool down, then clean the affected part with warm water and mild soap (never abrasive sponges on non-stick coatings). Reassemble, plug back in and run a short empty cycle to test.

Frequently asked questions
In Europe, any smart coffee machines bought new from an official reseller benefits from a legal conformity guarantee of at least two years (Directive (EU) 2019/771). This guarantee covers defects present at delivery, whenever they first manifest.
You can pick: European law puts the legal guarantee on the seller, not the manufacturer. In practice, a store return is usually faster, but the manufacturer can repair if the damage is out of warranty. Keep proof of purchase.
Our public methodology adds a Nura Score /10 penalty to any smart coffee machines whose recurring failures are documented in European user feedback. A model that breaks too often never tops our charts, brand notwithstanding.
Yes, within the limits of the European "right to repair": routine maintenance tasks (cleaning, gasket replacement, calibration) never void the legal warranty. Only irreversible hardware modifications can be a problem. For a smart coffee machines, any handling documented in the manufacturer's manual stays covered.
The directive imposes a two-year legal conformity guarantee, with a presumption of pre-existing defect during the first twelve months — the burden of proof is on the seller. For a smart coffee machines that breaks in that window, you're entitled to free repair or replacement, no strings attached on typical use.
