E10 appears and the cooker does not heat; sometimes accompanied by a faint click but no temperature rise.

Safety first: Unplug the cooker and ensure it is cool. Heating components operate at mains voltage; use caution.

• Check continuity of heating element: Remove the bottom cover to access the heating plate terminals. Use a multimeter to measure resistance across the heater. A typical value is 20–60 Ω. Infinite resistance indicates an open element.
• Inspect wiring: Look for burnt or discolored wires and loose spade connectors at the heater and board. Replace any damaged wiring with high-temperature rated cable.
• Test thermal fuse: Locate the thermal fuse in series with the heater. Check for continuity; if open, replace with the same rating.
• Control board output: If the heater and fuse are good, the triac or relay on the main board may have failed. Visual signs include cracking or burn marks. Board-level repair requires electronics skills; most users should replace the entire board.
