Safety first: Ensure the cooker is cool and not under pressure.

• Remove inner lid: Detach the removable inner lid plate (if present) by releasing its latch or screws.
• Tighten screws: Tighten any loose screws holding the inner lid, steam guide, or anti-block shield.
• Check float valve: Ensure the float valve pin and cap are properly assembled and not loose.
