Float valve does not rise during pressure cooking; cooker times out or shows pressure-related errors.

Safety first: Allow the cooker to cool and depressurize before working on the float valve.

• Clean float valve: Remove the float valve pin and silicone cap (if design allows). Clean all parts with warm soapy water and ensure the valve moves freely.
• Inspect silicone cap: Replace the cap if it is swollen, cracked, or hardened.
• Adjust recipes: Use enough thin liquid and avoid very thick sauces until after pressure cooking is complete.

A properly moving float valve is essential for safe pressure operation; replace the float valve kit if cleaning does not restore smooth movement.
