Float valve does not rise during pressure cooking; cooker times out or shows pressure-related errors.

Safety first: Allow the cooker to cool and ensure no pressure remains before working on the float valve.

• Clean float assembly: Remove the inner lid and gently push the float pin up and down. Clean around it with warm soapy water.
• Inspect silicone cap: Remove the silicone cap from the float pin and check for deformation or cracks. Replace if necessary.
• Check liquid level: Ensure you are using enough liquid for pressure cooking as specified in the Hisense manual.
• Reassemble and test: Refit the cap and inner lid, then run a water-only pressure test to confirm the float rises properly.
