Multicooker takes much longer than usual to come up to pressure.

Safety first: Monitor the cooker during extended preheat to ensure no abnormal steam leaks.

• Check for leaks: Look for continuous steam escaping from the lid or valve. Address sealing issues if present.
• Reduce batch size: Avoid overfilling the pot; cook large quantities in batches.
• Use warm liquid: Start with warm (not boiling) water or broth to reduce preheat time.
• Evaluate heater performance: If preheat times have increased significantly over time with similar recipes, the heating element may be weakening and require replacement.
