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

Safety first: Keep hands and face away from escaping steam. Turn off and unplug the cooker before inspecting the lid.

• 1. Verify valve position: Ensure the steam release valve is set to the Sealing position (not Venting) according to your Chefman model’s markings.
• 2. Inspect sealing ring: Remove the silicone ring from the lid. Check for cracks, hardening, or deformation. Replace if it is loose, stretched, or damaged.
• 3. Clean lid and rim: Thoroughly clean the stainless rim of the cooker body and the underside of the lid where the ring contacts. Even small food particles can prevent sealing.
• 4. Check float valve cap: Inspect the small silicone cap on the float valve pin. If it is cracked or missing, replace it with a compatible Chefman float valve cap.
• 5. Test with water: Reassemble and run a pressure test with 2 cups of water. If steam still leaks heavily, the lid assembly or inner pot rim may be warped and require replacement.
