Possible Causes

Cooking very starchy foods (e.g. porridge, pasta) at high pressure, Overfilling above MAX line, Blocked anti-foam/anti-block shield, Worn steam release valve

How to Fix / Troubleshooting

Safety first: Keep clear of the steam release area. Do not cover the valve.

  • Adjust recipes: For foamy foods, use lower pressure or slow cook mode, and never exceed recommended fill levels.
  • Clean anti-block shield: Remove and thoroughly clean the anti-block shield and steam release valve.
  • Use oil or fat sparingly: Excess fat can increase foaming; adjust recipe if needed.
  • When to replace: If the valve does not regulate steam smoothly after cleaning, replace the steam release valve assembly.
