Possible Causes

Cooking foamy foods (beans, grains) without enough oil or water, Clogged anti‑block shield, Overfilled pot, Rapid pressure release with starchy contents

How to Fix / Troubleshooting

Safety first: Keep hands and face away from the steam release. Hot liquid can cause severe burns.

  • Use natural release: For foamy foods, allow pressure to drop naturally for 10–15 minutes before opening the valve.
  • Clean anti‑block shield: Remove the metal shield under the steam release and clean thoroughly to ensure steam can pass freely.
  • Adjust recipes: Do not exceed half‑full for beans, grains, and foamy foods. Add a spoonful of oil to reduce foaming.
  • Inspect valve: If spurting continues despite proper use, replace the Cosori steam release valve assembly.
