Steam leaks continuously from the steam release valve during pressure cooking, and pressure never builds fully.

Safety first: Do not touch the valve while hot. Unplug and wait until pressure is fully released before disassembly.

• Check valve position: Ensure the steam release handle is turned to Sealing for pressure cooking.
• Clean valve: Remove the valve cap/handle and wash it with warm soapy water. Clear any food particles from the vent path.
• Inspect seal and spring: Check the silicone or rubber seal and internal spring (if accessible) for wear or deformation. Replace if damaged.
• Reassemble correctly: Install the valve according to the manual, ensuring it seats properly.

If steam still leaks heavily, replace the steam release valve assembly.
