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

Safety: Unplug the cooker and let it cool. Do not add cold water to a hot dry pot as it may warp.

Steps:

• Check inner pot seating: Remove the pot, clean the underside, and inspect the heating plate for debris or dents. Reseat the pot, ensuring it sits flat and can rotate slightly when pressed down.
• Inspect pot condition: Place the pot on a flat countertop and check for rocking. If the base is warped, replace the Russell Hobbs non-stick inner pot.
• Ensure adequate liquid: For pressure or rice programs, ensure you meet the minimum liquid requirement specified in the manual (typically at least 250–500 ml). Running dry will trigger E3.
• Clean sensor area: Wipe the heating plate and center sensor area with a soft dry cloth. Remove any burnt food or sugar that can cause localized overheating.
• Test on a low setting: After cleaning and reseating, run a low‑temperature program with sufficient water. If E3 still appears quickly, the overheat detection circuit on the control PCB may be faulty.

Warning: Do not bypass or short any safety sensors. If the error persists after basic checks, seek professional service.
