Float valve does not rise during pressure cooking, and steam leaks continuously from its opening.

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

• Disassemble float valve: Remove the small retaining clip or nut and slide out the float pin and gasket.
• Clean thoroughly: Wash all parts with warm soapy water and clean the valve channel in the lid with a brush.
• Inspect gasket: Replace the silicone gasket if it is stiff, cracked, or misshapen.
• Reassemble correctly: Install the float pin and gasket in the correct orientation and secure with the clip.
• Test pressure build: Run a short pressure cycle with water and confirm that the float rises and seals properly.

Warning: Do not plug the float valve opening with foreign materials; use only proper replacement parts.
