Lid is stuck and will not open after cooking; float valve appears down but the lid mechanism will not release.

Safety first: Confirm that pressure is fully released. Gently nudge the float valve with a utensil; it should move freely and be in the down position. Never force the lid if there is any sign of pressure.

• Allow extra cooling time: Sometimes residual pressure keeps the lock engaged. Wait an additional 15–20 minutes and try again.
• Gently wiggle lid: With both hands on the lid handle, gently twist back and forth within the normal unlock range while lifting slightly. Do not use tools or excessive force.
• Clean lock channel: Once open, disassemble the lid lock cover (if removable) and clean the channel and pin with warm soapy water to remove dried food.
• Inspect for damage: Check the locking pin and spring for bending or wear. Replace the lid lock assembly if parts are deformed.

If the lid remains stuck despite no pressure and gentle attempts, seek professional assistance to avoid damaging the safety mechanisms.
