Multicooker powers on and counts down, but food remains undercooked; inner pot is only lukewarm.

Safety first: Unplug and cool before internal checks.

• Verify cooking settings: Ensure you are using the correct program and not only the Keep Warm function.
• Check with water test: Add 3–4 cups of water and run a high-heat program. After 10 minutes, the water should be vigorously boiling or under pressure (for pressure modes).
• Listen for cycling: During heating, you should hear occasional relay clicks. No clicks or very infrequent clicks can indicate a control issue.
• Internal diagnosis: If heating is consistently weak, the heating element or control board must be tested and likely replaced.
