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

Safety first: Unplug before removing covers; heating components can remain hot after use.

• Test with water: Add 1 liter of water and start a high-temperature program (e.g., fry). Water should begin to steam within a few minutes. If not, heating is weak.
• Check power source: Avoid long, thin extension cords that can cause voltage drop. Plug directly into a wall outlet.
• Inspect heater wiring (advanced): Remove the bottom cover and check heater terminals for discoloration or loose connectors. Tighten or replace burnt connectors.
• Sensor check: If the cooker prematurely thinks it has reached temperature, the NTC sensor may be out of calibration. This requires testing and likely replacement by a technician.
