Multicooker will not build pressure; timer does not start counting down and steam continuously escapes.

Safety first: Keep clear of escaping steam during preheat.

• Check valve position: Ensure the steam release valve is turned to the SEAL or PRESSURE position for pressure cooking.
• Inspect gasket: Remove and examine the large silicone gasket. Clean it and the lid groove with warm soapy water, dry, and reinstall. Replace if stretched or cracked.
• Clean sealing surfaces: Wipe the stainless rim of the inner pot and the lid sealing surface to remove food residue.
• Check float valve: Ensure the float valve moves freely and its O-ring is intact. Replace the O-ring if worn.
