Steam constantly vents from the steam release valve and pressure never builds.

Safety first: Keep clear of the steam plume; it can cause severe burns.

• Check valve position: Ensure the steam release knob is turned to the 'Sealing' position for pressure cooking.
• Clean valve: After cooling, remove the valve cap and clean all parts with warm soapy water. Ensure the silicone gasket is free of residue.
• Inspect gasket and spring: Check the small silicone seal and spring (if fitted) for wear, cracks, or deformation. Replace if damaged.
• Reassemble correctly: Refit the valve components in the correct order as per the Lakeland manual.
• When to replace: If the valve still leaks in the sealing position, replace the complete steam release valve assembly.
