Rattling or vibration noise from the lid area during pressure cooking.

Safety first: Do not touch the lid while under pressure. Wait until fully depressurized.

• Tighten removable parts: After cooling, ensure the steam release valve cap is properly seated and tightened as per design.
• Check inner lid plate: Remove the inner lid and tighten any screws holding the plate or anti-block shield.
• Inspect float valve: Ensure the float valve pin is not excessively loose. Replace if worn.
• Test again: Run a water-only pressure test to confirm the noise is reduced.
