Unit heats but never reaches or maintains pressure; steam constantly escapes from lid during pressure cook.

Safety first: Do not touch escaping steam. Allow the cooker to cool and depressurize before working on the lid.

• Verify valve position: Ensure the steam release valve is set to Seal, not Vent.
• Inspect sealing ring: Remove, clean, and carefully reinstall the main silicone sealing ring. Replace if stretched or cracked.
• Clean lid rim: Wipe the lid and body rims to remove food residue that could prevent a tight seal.
• Check float valve gasket: Remove the float valve and inspect its small silicone cap. Replace if worn.
• Test with water only: Run a short pressure cycle with just water to confirm that pressure can build without food interference.
