Multicooker heats but never reaches pressure; steam constantly escapes from lid.

Safety first: Allow the cooker to cool and depressurize before working on the lid.

• Check steam release position: Ensure the steam release handle or valve is set to the sealing position for pressure cooking.
• Inspect and clean gasket: Remove, wash, and reinstall the lid gasket, checking for cracks or deformation. Replace if worn.
• Clean rim and lid: Wipe the pot rim and lid sealing surface to remove food residue.
• Check float valve seal: Inspect the small silicone cap on the float valve; replace if cracked or hardened.

When to call a technician: If pressure still does not build with new seals and correct settings, the pressure sensor or lid assembly may require professional service.
