E3 appears during preheat or pressure build-up; unit stops heating and may beep continuously.

Safety: Unplug the cooker and allow it to cool completely. Do not touch the heating plate while hot.

• Check pot seating: Remove the inner pot and inspect the heating plate. Ensure there is no debris or food residue preventing full contact. Clean the plate with a soft, damp cloth (unit unplugged).
• Inspect inner pot: Place the pot on a flat surface and check if it rocks or is visibly warped. A warped pot can cause hot spots and trigger E3. Replace the pot if deformed.
• Avoid dry heating: Ensure there is sufficient liquid in the pot for the selected program. Running high-heat programs with very little liquid can cause overheat errors.
• Check thermal cutoff: From the underside, locate the thermal fuse/thermal cutoff attached near the heating plate. If it has opened (no continuity), the unit may overheat or fail to regulate temperature. Replace with the same rating if defective.
• Test again: After cleaning and verifying the pot, add at least 2 cups of water and run a low-pressure or sauté program to confirm normal operation.
