E15 appears and the cooker immediately shuts off heating; sometimes accompanied by a strong smell of burning.

Safety first: Immediately unplug the cooker. Do not continue to operate until the cause is identified. If there is visible smoke or flames, use appropriate fire safety measures.

Step-by-step checks:

• 1. External ventilation: Ensure the cooker is used on a hard, heat-resistant surface with at least several centimeters of clearance on all sides. Do not operate under low cabinets where steam and heat accumulate.
• 2. Inspect bottom vents: Check the bottom and side ventilation slots for dust, grease, or obstructions. Clean with a soft brush and vacuum.
• 3. Internal inspection (advanced): Remove the bottom cover and inspect for melted plastic, burnt wiring, or charred insulation around the heater and thermostat.
• 4. Check thermostat and thermal fuse: Test continuity of the thermostat and thermal fuse. A thermostat stuck closed combined with a failed sensor can cause dangerous overheating.
• 5. Do not bypass safety devices: If any safety component has opened (blown thermal fuse), replace it with the correct Saturn-specified part; never short it out.

Recommendation: Due to the risk of fire, any unit that has triggered E15 with signs of overheating should be inspected by a professional technician before further use.
