Multicooker heats but never reaches or holds pressure (steam constantly escaping from lid)

Safety first: Do not place hands or face near escaping steam. Allow the cooker to cool and depressurize before servicing.

• Inspect sealing ring: Remove the silicone ring and check for cracks, hardening, or deformation. Replace if more than 12–18 months old or visibly worn.
• Clean sealing surfaces: Wipe the lid groove and top rim of the cooker body to remove food residue.
• Check float valve: Disassemble the float valve and clean the pin and silicone gasket. Ensure it moves freely and seals properly.
• Inspect steam release valve: Remove and clean the valve. Check the silicone cap or gasket for damage and replace if needed.
• Test with water: After reassembly, run a water‑only pressure test. If steam still leaks, replace the Cosori silicone sealing ring and float valve gasket set.
