Instant Pot displays E4 and will not start or stops mid-cycle.

Safety: Unplug and allow the unit to cool fully. Do not continue using if there is a burning smell or visible damage.

• 1. Inspect inner pot: Check for heavy discoloration, pitting, or warping on the bottom. Replace the pot if damaged.
• 2. Clean heating plate: Remove any burnt residue from the heating plate with a soft cloth. Do not use abrasive pads that can damage the surface or sensor.
• 3. Test with water: After cleaning, run a short pressure cook or steam cycle with only water. If E4 recurs, internal components are likely damaged.
• 4. Professional calibration/repair: A technician can test the temperature sensor values and replace the sensor or main control board if readings are out of range.
• 5. Discontinue use if damage is visible: If you see melted plastic, cracked heating plate, or burnt wiring smell, stop using the cooker and seek professional service or replacement.
