Display shows E6 and cooker will not start or stops during preheat

Safety first: Unplug the cooker. Do not bypass safety devices such as thermal fuses.

• Check for heat: Start a cycle with 2–3 cups of water and feel (carefully) if the heating plate warms at all before E6 appears. No warmth suggests an open heater circuit.
• Inspect wiring: Remove the bottom cover and inspect the heavy‑gauge wires from the control board to the heating plate. Look for burned connectors, loose spades, or broken wires. Repair or replace as needed.
• Test heating element: Disconnect the heater leads and measure resistance across the heating plate terminals. A typical value is between 20–60Ω. Infinite resistance indicates an open element that must be replaced.
• Check thermal fuse: Locate the inline thermal fuse mounted near the heating plate. Test for continuity; an open fuse indicates it has blown due to overheat and must be replaced with the same rating.
• Control board components: If the heater and fuse test good, the triac or relay on the main control board may have failed. This requires board‑level repair or full board replacement by a qualified technician.
