Float valve does not rise; cooker never indicates that pressure has been reached.

Steps:

• Ensure you have at least the minimum required liquid in the inner pot.
• After cooling and depressurizing, remove the float valve pin and its silicone O-ring as per the manual.
• Clean the float valve channel in the lid with warm soapy water and a small brush to remove any residue.
• Inspect the O-ring for cracks or flattening. Replace if worn.
• Reinstall the float valve in the correct orientation and ensure it moves freely up and down.
• Test with a water-only pressure cycle to verify that the float rises and seals.
