Possible Causes

Overfilled pot with starchy foods, Clogged or missing anti-block shield, Rapid pressure release with foamy contents

How to Fix / Troubleshooting

Safety first: Keep face and hands away from the valve; hot liquid can cause severe burns.

  • Stop the cycle: Cancel cooking and allow pressure to drop naturally.
  • Check fill level: Ensure you are not exceeding the recommended fill line for beans, rice, or foamy foods.
  • Clean anti-block shield: Remove and clean the shield under the lid to ensure it is not blocked or missing.
  • Use natural release: For foamy foods, use natural pressure release instead of quick release.

Persistent spitting despite proper fill and shield cleaning may require replacing the anti-block shield or steam release assembly.
