Multicooker overheats; food burns on the bottom even when using sufficient liquid and correct settings.

Safety first: Unplug the cooker and allow it to cool. Avoid touching the hot plate or pot.

Steps to address overheating:

• 1. Verify recipe and liquid: Ensure you are following Steba's recommended liquid amounts and not using high-heat modes for delicate foods.
• 2. Clean sensor and plate: Remove burnt residue from the heating plate and sensor disc. Build-up can cause incorrect temperature readings.
• 3. Check sensor mounting: With the base removed, confirm that the NTC sensor is firmly pressed against the underside of the heating plate (if mounted below). Re-secure any loose brackets or clips.
• 4. Test NTC resistance curve: Measure NTC resistance at room temperature and again after gently warming the sensor (e.g., with a hair dryer at a distance). Resistance should decrease smoothly. Replace the sensor if readings are erratic.
• 5. Inspect heater relay: If the relay contacts are welded closed, the heater may stay on continuously. Replace the main control board if the relay is stuck.

If overheating persists after sensor replacement, discontinue use and have the control system professionally checked.
