Rattling or vibration noises from the lid area when steam is released or during pressure cooking.

Safety: Keep clear of hot steam; service only when cool.

• 1. Tighten removable parts: Remove and reinstall the steam release valve, ensuring it is fully seated. Confirm the anti-block shield is firmly clipped.
• 2. Inner lid plate: Tighten any screws holding the inner lid plate. Replace missing screws with correct Toshiba parts.
• 3. Float valve: Check that the float valve pin and cap are not excessively worn and that they move smoothly without excessive play.

Do not use adhesives or tape on lid components; they must move freely for safe pressure control.
