Possible Causes

Overfilled inner pot, Cooking foamy foods without enough headroom, Anti-block shield clogged with starch, Steam release valve partially blocked

How to Fix / Troubleshooting

Safety first: Keep clear of the steam path. Turn off the cooker and allow pressure to drop before cleaning.

Step-by-step checks:

  • 1. Check fill level: Ensure you are not filling above the MAX line, and for beans, grains, and soups, stay below 2/3 full.
  • 2. Use oil for foamy foods: Adding a small amount of cooking oil can reduce foaming in some recipes.
  • 3. Clean anti-block shield and valve: Remove and thoroughly clean the anti-block shield and steam release valve. Ensure all small holes are clear.
  • 4. Rinse lid channels: Rinse the lid under warm water to clear any internal passages of starch buildup.

Recommendation: If spurting continues despite correct filling and cleaning, replace the steam release valve assembly.
