Lid is stuck and cannot be opened after cooking; float valve appears down and no steam is visible.

Safety first: Confirm there is no pressure: gently move the steam release valve to venting; if no steam escapes and float valve is down, pressure is released.

• Gentle rocking: With the cooker unplugged, gently press down on the lid and try to rotate or open according to the manual. Do not force with tools.
• Clean around lock: If a small gap exists, use a thin plastic tool or cloth to remove visible food debris around the lock area.
• Allow cooling: Sometimes vacuum can hold the lid; wait until the cooker is fully cool and try again.

When to call a technician: If the lid remains stuck, the lock may need to be disassembled from inside by a professional to avoid damage.
