During preheat or pressure build-up, the display shows E3 and the cooker stops heating.

Safety first: Unplug the cooker and allow it to cool fully. Do not add water to a very hot dry pot.

• Check liquid level: Open the lid and verify there is enough liquid for the selected program (pressure programs typically require at least 250 ml). Add liquid if necessary.
• Inspect for burnt-on food: Remove the inner pot and check the bottom for scorched food. Soak and clean thoroughly. Wipe the underside of the pot and the heating plate with a soft, damp cloth (unit unplugged).
• Verify pot seating: Ensure the stainless steel inner pot is fully seated and flat on the heating plate. Rotate it gently to confirm it is not rocking on debris or a warped base.
• Cool-down reset: Let the unit cool for at least 20–30 minutes, then plug back in and try a simple program with adequate liquid.
• When to replace: If E3 appears quickly even with proper liquid and a clean pot, the base NTC temperature sensor may be faulty and require replacement.
