Multicooker heats very slowly or never reaches the set temperature; food remains undercooked.

Safety first: Unplug the unit and allow it to cool before inspection.

• Test with water: Add 2–3 cups of water and select a high-heat mode (e.g., "Sear/Sauté"). The water should begin to simmer within a few minutes. If not, heating is inadequate.
• Check power supply: Ensure the cooker is connected to the correct mains voltage specified on the rating label.
• Inspect heating plate: Look for discoloration or warping that may indicate overheating damage.
• Internal diagnosis: Weak heating typically indicates a failing element or control board component and requires professional electrical testing and replacement.
