Steam vent cap rattles excessively or pops off during cooking.

Safety first: For pressure-capable models, never cover or block the steam vent. Allow the unit to cool before handling the vent cap.

• Clean vent cap: Remove the cap and wash it thoroughly. Clear any buildup from the vent hole.
• Clean vent seat: Wipe the area where the cap sits on the lid to ensure a flat, clean surface.
• Check cap fit: Reinstall the cap and verify it seats firmly. If it is loose or deformed, replace it.
• Descale if needed: If you have hard water, soak the cap in vinegar to dissolve mineral deposits.
