Loud hissing, rattling, or whistling noises from the lid during pressure cooking.

Safety first: Keep clear of the steam path. Do not cover the valve. Allow the cooker to depressurize before disassembly.

Steps to resolve:

• Review recipe and fill level: Avoid overfilling and reduce foaming ingredients like pasta, beans, or porridge. Add a small amount of oil to reduce foam.
• Clean valve and shield: Remove and thoroughly clean the steam release valve and anti-block shield to ensure smooth steam flow.
• Check valve seating: Ensure the valve cap is properly seated and not loose or tilted.
• Test with water: Run a water-only pressure cycle to confirm that noise is reduced when food foam is not present.

When to call a technician: Persistent abnormal noise with clean components may indicate a defective valve or pressure regulator that should be replaced.
