Float valve does not rise; cooker never indicates it is at pressure.

Safety first: Ensure there is no pressure before touching the float valve.

• Check liquid level: Open the lid and confirm there is enough liquid in the pot.
• Clean float valve: Remove the float valve pin and silicone cap (per manual). Clean all parts and the valve channel in the lid.
• Inspect silicone cap: Replace the cap if it is swollen, cracked, or hardened.
• Reassemble and test: Reinstall the float valve, ensuring it moves freely. Run a water-only pressure test to confirm it rises properly.
