E6 appears on the display and the unit will not heat or start any cooking mode.

Safety first: Unplug the multicooker and allow it to cool. Internal electrical checks should only be done if you are comfortable working with appliances.

• 1. Visual inspection: Remove the inner pot and inspect the heating plate for obvious burn marks, cracks, or deformation.
• 2. Access heater connections: With the unit unplugged, remove the bottom cover. Locate the two heavy-gauge wires leading to the heating element ring or plate.
• 3. Check connectors: Ensure the spade terminals are firmly attached and not oxidized or burned. Clean light oxidation with fine sandpaper and reattach securely.
• 4. Test heater resistance: Using a multimeter, measure resistance across the heating element terminals. Typical values are between 20–60Ω depending on wattage. An open circuit indicates a failed heater that must be replaced.
• 5. Inspect thermal fuse: Look for an inline thermal fuse attached to the heater or wiring harness. Test for continuity; if open, replace with the same temperature and current rating.

If the heater and thermal fuse test good but E6 remains, the heater relay or triac on the main PCB may be defective and the board should be replaced by a technician.
