Multicooker displays E1 shortly after powering on and will not start any cooking program.

Safety first: Unplug the Sencor multicooker from the mains and allow it to cool completely before opening the lid or removing any covers.

• Inspect the lid sensor cable: Open the lid fully and locate the thin cable or flex harness that runs from the lid hinge area into the body. Check for pinched, cut, or broken insulation.
• Check lid sensor connector: Remove the inner lid and steam cap. From the top or hinge area, gently pull back the plastic trim (if accessible) and verify the lid sensor connector is firmly seated in its socket. Reseat it several times to clear oxidation.
• Clean contacts: If you can access the control PCB area (usually under the top cover), inspect the small 2‑wire connector labeled for the lid NTC or lid sensor. Use electrical contact cleaner and a cotton swab to clean the pins.
• Measure sensor resistance (advanced): With the unit unplugged, disconnect the lid sensor and measure resistance across the two pins with a multimeter. A typical NTC will read between 5–100 kΩ at room temperature. An infinite (OL) reading indicates an open sensor that must be replaced.
• Replace lid sensor assembly: If the harness is damaged or the NTC is open, replace the complete lid temperature sensor harness designed for your Sencor model. Route it through the hinge exactly as the original to avoid future pinching.

If E1 persists after these checks, the control board’s sensor input circuit may be damaged and should be evaluated by a qualified technician.
