Steam or liquid spurts from the steam release valve more violently than usual during pressure cooking or release.

Safety first: Allow the cooker to cool and depressurize completely. Never attempt to remove parts while under pressure.

• Disassemble lid components: Remove the steam release valve, anti-block shield, and float valve according to the Nesco manual.
• Thorough cleaning: Soak removable parts in warm soapy water, then scrub gently with a small brush. Use a pipe cleaner or thin brush to clear the steam channel.
• Inspect for damage: Check the anti-block shield for warping or cracks and the float valve for deformation. Replace any damaged parts.
• Correct reassembly: Reinstall all parts in the correct order and orientation, ensuring they move freely.
• Test release: Run a short pressure cycle with water and perform a controlled steam release to confirm smooth operation.

Warning: Never cover the steam release valve with cloth or other materials to control spurting; fix the underlying blockage instead.
