Inner lid plate or anti-block shield repeatedly falls off or does not stay in place.

Safety first: Ensure the cooker is unplugged and cool before working on the lid.

Steps to resolve:

• Check assembly order: Refer to the Siemens manual to confirm the correct orientation and order of inner lid parts.
• Inspect clips and screws: Look for cracked plastic clips or missing screws that hold the inner lid in place. Replace damaged parts.
• Ensure firm engagement: When reinstalling, press until you hear or feel a click, indicating the plate is locked.

When to call a technician: If the lid frame itself is damaged or warped, the entire lid assembly may need replacement by a service center.
