Float valve does not rise during pressure cooking; cooker times out or food is undercooked.

Safety first: Turn off the cooker and allow it to cool and depressurize before disassembling the float valve.

• Clean float valve: Remove the inner anti-block shield and gently push the float pin up and down. Clean any residue with warm soapy water.
• Inspect silicone cap: Check the small silicone cap on the float for cracks or deformation. Replace if damaged.
• Check liquid level: Ensure you are using enough liquid for the recipe and not exceeding the maximum fill line.
• Reassemble and test: Refit all parts and run a short pressure test with water.
