E9 appears and the cooker will not start; sometimes accompanied by a faint burning smell previously.

Safety first: Immediately unplug the cooker. Do not attempt to power it on again until inspected. Risk of electric shock and fire.

• Visual and smell check: After cooling, remove the bottom cover and inspect for burnt wiring, blackened PCB areas, or melted plastic.
• Check heater terminals: Inspect the heating plate terminals for signs of arcing or melted insulation. Ensure no wires are touching the metal chassis.
• Test heater to chassis (advanced): With a multimeter, check for continuity between each heater terminal and the metal body. Any continuity indicates a shorted element that must be replaced.
• Inspect PCB components: Look for a shorted triac, relay, or MOV surge suppressor. Burnt or cracked components require PCB replacement.
• Dry out moisture: If there are signs of condensation or liquid ingress, dry the unit thoroughly and identify the source of the leak before reuse.
• Replace damaged parts: Install a new heating plate assembly or main control board as needed, using Hisense-approved components. If multiple parts are damaged, replacement of the entire unit may be more economical.
