Float valve does not rise; the cooker never reaches pressure even though steam is present.

Safety first: Avoid touching the float valve while hot.

• Check fill level: Ensure you have at least the minimum required liquid and are not exceeding the maximum fill line.
• Clean float valve: After cooling, remove the float valve pin and silicone cap (if removable). Clean all parts and the valve channel.
• Inspect silicone cap: Replace if cracked, swollen, or hardened.
• Reassemble and test: Run a water-only pressure cycle to verify the float rises and seals.
