Multicooker shows E10 and aborts pressure cooking, often before reaching full pressure.

Safety first: Allow the cooker to cool and depressurize fully before opening the lid.

• Inspect sealing ring: Remove the inner lid (if applicable) and take out the silicone sealing ring. Check for cracks, hardening, or deformation. Clean it with warm soapy water and dry thoroughly.
• Reinstall correctly: Ensure the sealing ring is evenly seated in its groove all around the lid. An uneven ring will cause leaks and E10 errors.
• Check float valve and cap: Remove the float valve and its silicone cap. Clean both parts and the valve channel. Replace the cap if it is loose or cracked.
• Look for visible steam leaks: During a test run with water only, observe the lid area. Continuous steam escaping from the edge of the lid or around the valve indicates a sealing issue.
• Replace worn seals: If the sealing ring or float valve components show wear, replace them with original Xiaomi sealing parts designed for your model.
• Check lid deformation: If the metal lid or inner cover appears warped or bent, it may not seal properly and may need replacement.
• Service if needed: If all seals are new and correctly installed but E10 persists, the pressure sensor calibration or control board may be faulty and should be checked by a technician.
