E3 appears on the display during preheating or pressure build-up and cooking stops.

Safety first: Disconnect power and allow the cooker to cool completely before touching internal surfaces.

• Verify bowl placement: Ensure the original Tefal inner bowl is used. Remove it, clean the outer surface, and reseat it so it sits flat and rotates freely if designed to do so.
• Clean heater plate: With the unit unplugged and cool, wipe the heater plate with a soft damp cloth to remove burnt food or starch. Dry thoroughly.
• Check bowl condition: Inspect the bottom of the bowl for warping, dents, or peeling coating. A warped bowl can cause poor contact and localized overheating.
• Try a low-heat program: After cleaning and reseating, run a warm or reheat program with a small amount of water (e.g., 500 ml). If E3 reappears quickly, the thermal protection or heater control may be faulty.
• Advanced repair: A failing thermal fuse or thermostat on the heater plate may need replacement. This requires opening the base and working with mains wiring; if you are not trained, contact a service center.
