Loud hissing and sputtering from the steam release valve; liquid sprays out during cooking.

Safety first: Keep clear of the steam release area. Allow the cooker to finish or cancel and depressurize safely before cleaning.

Usage corrections:

• Ensure the pot is not filled above the recommended level (usually 1/2 full for beans, grains, and foamy foods).
• Add 1–2 teaspoons of oil to reduce foaming when cooking starchy foods.

Cleaning:

• Remove and thoroughly clean the steam release valve and anti-block shield.
• Inspect the valve seal; replace the steam release valve assembly if the seal is hardened or damaged.
