Display shows E3 during cooking; unit stops heating and may beep continuously.

Safety first: Unplug the multicooker and let it cool fully. Do not touch the heating plate while hot.

Step-by-step checks:

• 1. Check inner pot seating: Ensure the Saturn inner pot is the original one, not deformed, and sits flat on the heating plate. Remove and reseat it, rotating slightly to ensure full contact.
• 2. Clean the heating plate: Remove the pot and inspect the heating plate for burnt-on food, sugar, or oil. Clean gently with a non-abrasive sponge and mild detergent. Dry completely before use.
• 3. Avoid dry heating: Confirm you always use sufficient liquid for pressure or stew modes. Running the cooker nearly dry can trigger overheat and E3.
• 4. Inspect sensor area: Look at the central raised area where the sensor touches the pot. Ensure it is not bent or pushed down. A deformed plate can cause hot spots.
• 5. Internal inspection (advanced): With the unit unplugged and bottom cover removed, locate the NTC sensor on the heating plate. Check for signs of scorching or melted plastic around the sensor. Verify the sensor wires are not pinched or touching the heater terminals.
• 6. Test with water only: After cleaning and reassembly, add 2–3 cups of water and run a basic cooking program. If E3 appears again quickly, the NTC sensor is likely shorted or out of spec and should be replaced.

Warning: Do not bypass the temperature sensor; it is a critical safety component that prevents overheating and fire.
