Multicooker beeps and displays E1 shortly after starting; heating does not begin or stops immediately.

Safety first: Unplug the PowerXL multicooker and allow it to cool completely before opening or touching internal parts. Never work on the unit while it is connected to power.

• 1. Power reset: Unplug the cooker for 10 minutes, then plug back in and try a simple cooking program with an empty, dry inner pot. If E1 clears temporarily, the issue may be intermittent wiring.
• 2. Inspect bottom sensor wiring: Remove the inner pot and look at the center of the heating plate. Most PowerXL multicookers have a temperature sensor (small metal disc or probe) attached under the plate. From the underside (after removing the bottom cover), check that the sensor leads are firmly plugged into the main control board and not pinched or broken.
• 3. Check for corrosion or moisture: Look for signs of liquid intrusion around the sensor connector. If you see corrosion, gently clean the connector with isopropyl alcohol and a soft brush, then let it dry fully before reassembly.
• 4. Test continuity (advanced): With a multimeter set to resistance (ohms), test the NTC thermistor leads. A typical sensor will show a finite resistance (often 50–200 kΩ at room temperature). If the reading is infinite (open circuit), the sensor is defective and must be replaced.
• 5. Replace the temperature sensor: If wiring is intact but E1 persists and the sensor tests open, replace the bottom temperature sensor / NTC thermistor with a compatible PowerXL part. Reassemble the base, ensuring wires are routed away from hot surfaces.
• 6. Do not bypass the sensor: Never short or bypass the temperature sensor; this can cause overheating and fire risk.
