Possible Causes
Overfilled inner pot, Cooking very starchy or foamy foods without enough oil or water, Blocked anti-block shield redirecting foam, Worn sealing components causing unstable boiling
How to Fix / Troubleshooting
Safety first: Keep hands and face away from the steam outlet. Allow the cooker to depressurize before cleaning.
- Reduce fill level: For foamy foods (beans, porridge, pasta), fill only to the lower max line or 1/2–2/3 of capacity.
- Use oil or pre-rinse: Add a small amount of oil or pre-rinse starchy foods to reduce foam.
- Clean anti-block shield: Remove and thoroughly clean the anti-block shield and steam path.
- Check sealing ring: Replace if worn, as poor sealing can cause unstable boiling and surging.
