E6 error appears during operation; cooker may stop heating or behave erratically.

Safety first: Unplug the multicooker and wait several minutes for internal capacitors to discharge. Do not work on live circuits.

• Visual inspection of power cord and plug: Check for burn marks, cuts, or loose prongs. Replace the cord set if damaged.
• Check for burning smell or discoloration: Remove the bottom cover (unplugged) and inspect the control/power board for burnt components or darkened areas near the heater terminals.
• Inspect heater connections: Verify that the spade connectors to the main heating element are tight and not oxidized. Reseat them if loose.
• Test heating element resistance: With a multimeter, measure resistance across the heating element terminals. A typical value is between 20–60 Ω depending on model. A dead short (near 0 Ω) or open circuit indicates a bad element.
• Board-level repair: If the element tests good, the triac or relay on the control board may be faulty. This usually requires replacing the entire control board or having it repaired by an electronics specialist.

Due to mains voltage risks, non-professionals should avoid detailed board repair and instead replace the complete control module.
