C210 error, appliance reports overfill or safety overflow condition

Safety first: Beware of hot steam and splashes when opening the lid. Unplug before cleaning.

• 1. Reduce fill level: Ensure the bowl is never filled above the MAX mark, especially for boiling or mixing foamy foods.
• 2. Clean lid and sensors: Remove the lid and clean any foam or residue from the underside, including any visible sensor areas or steam outlets.
• 3. Check measuring cup/insert: Ensure the measuring cup or lid insert is correctly positioned to allow steam to escape as designed.
• 4. Retry with smaller batch: After cleaning and reducing volume, restart the program.
• 5. Persistent false triggers: If C210 appears even with low fill and clean lid, the overflow/foam sensor may be faulty and require replacement.
