Steam release valve is difficult to turn or feels stuck in one position.

Safety first: Ensure the cooker is cool and fully depressurized before attempting to move or remove the valve.

• Remove valve: Lift or unscrew the steam release valve according to the manual.
• Soak and clean: Soak the valve in warm soapy water and scrub gently to remove buildup. Clean the valve seat on the lid as well.
• Inspect for warping: If the valve appears melted, distorted, or cracked, replace it with a genuine Nesco valve.
• Lubrication caution: Do not use oils or greases on the valve; they can degrade silicone and attract debris.
• Reinstall and test: Refit the valve and ensure it rotates smoothly between venting and sealing positions.

Warning: Forcing a stuck valve can break internal parts and compromise pressure safety.
