Multicooker takes an unusually long time to come to pressure compared to normal operation.

Safety first: Avoid opening the lid until you are sure the cooker is not under pressure.

• Check recipe and liquid: Ensure you are using enough thin liquid as recommended in the manual.
• Inspect for leaks: Look for visible steam escaping from the lid or valve during preheat.
• Clean valve and ring: Remove and clean the steam release valve and sealing ring.
• Preheat ingredients: For very cold or frozen foods, consider partially thawing or using warm liquid to reduce preheat time.
