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

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

• Check steam release position: Ensure the valve is set to 'Seal' and not 'Vent'.
• Inspect and clean sealing ring: Remove the silicone ring, wash with warm soapy water, and inspect for cracks or flattening. Replace if not perfectly elastic.
• Clean lid and pot rim: Wipe the metal rim of the inner pot and the lid sealing surface to remove food residue.
• Check steam release valve: Remove and clean the valve. Ensure it moves freely and is not stuck by dried starch.
• If leakage continues, replace the main sealing ring and, if necessary, the steam release valve assembly.
