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

Safety first: Turn off and unplug the cooker. Allow it to cool and depressurize before disassembling any lid components.

• Check valve position: Ensure the steam release valve is set to the 'Sealed' or pressure position according to the Salter model markings.
• Clean float valve: Remove the float valve pin and silicone cap from the lid (usually held by a small retaining clip). Clean all parts and the valve channel.
• Inspect silicone seal: Replace the float valve seal if it is cracked, hardened, or missing.
• Verify lid lock: Close the lid firmly until the locking mechanism clicks. A partially closed lid will prevent pressure build-up.

Reassemble and run a water-only test. If the float still does not rise, inspect the lid sealing ring and steam release valve for leaks.
