Steam leaks continuously from the steam release valve during pressure cooking, and cooking time is extended.

Safety first: Do not touch the valve while hot. Allow the cooker to cool and depressurize before disassembly.

Steps to resolve:

• Verify valve position: Ensure the steam release valve is set to the correct position for pressure cooking as indicated in the Siemens manual.
• Clean the valve: Remove the valve and wash it thoroughly with warm soapy water. Clear any starch or food residue from internal passages.
• Inspect the seal: Check the silicone or rubber seal inside the valve for cracks or deformation. Replace the valve assembly if the seal is compromised.
• Check anti-block shield: Clean the anti-block shield under the lid to ensure proper steam flow to the valve.

When to call a technician: If the valve still leaks after cleaning and replacement, the pressure control system may be misregulated and should be inspected professionally.
