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

Safety first: Keep hands away from escaping steam. Turn off and unplug the cooker, then allow it to cool and depressurize.

• Check steam release knob: Ensure it is set to the sealing position for pressure cooking. Clean the knob and its seat to remove any food residue.
• Inspect lid gasket: Remove the gasket, wash it, and check for cracks or flattening. Replace if it no longer fits snugly in the lid groove.
• Clean sealing surfaces: Wipe the top rim of the inner pot and the corresponding lid surface to remove oil or food that can prevent a tight seal.
• Examine float valve: Make sure the float pin moves freely and that its silicone cap is intact. Replace the cap if it is hardened or split.
• Test with water: Run a pressure cycle with only water to confirm that pressure now builds and steam leakage stops.

Warning: Never cover the steam vent with cloth or other objects to stop leaks; fix the sealing components instead.
