Multicooker takes an unusually long time to reach pressure or never reaches full pressure.

Safety first: Keep hands and face away from the steam release area during operation.

• Check sealing ring: Remove the silicone sealing ring from the lid and inspect for cracks, stretching, or hardening. Replace if it is not supple and round.
• Verify valve position: Ensure the steam release valve is set to 'Sealing' or the pressure icon, not 'Venting'.
• Inspect lid fit: Close and lock the lid firmly. If you see steam escaping around the rim during preheat, the lid is not sealing properly.
• Clean lid components: Clean the steam release valve, anti-block shield, and safety valve to ensure they move freely and seal correctly.
• When to replace: If the cooker still fails to reach pressure, replace the silicone sealing ring and, if necessary, the steam release valve assembly.
