Lid is stuck and will not open after cooking; float valve appears down and no error code is shown.

Safety first: Confirm there is no pressure: the float valve must be fully down and no steam should escape when gently nudging the valve.

• Gently wiggle lid: With the cooker unplugged, gently twist the lid back and forth while lifting the handle. Do not force it.
• Inspect lock slot: Shine a light into the lock slot and use a thin plastic tool to dislodge any visible food debris.
• Check hinge alignment: Once open, inspect the hinge screws and lid alignment. Tighten loose screws.
• Lubricate lightly: Apply a tiny amount of food-safe silicone lubricant to the lock hook if it feels rough (avoid excess).
