E9 error appears and the cooker will not heat; sometimes occurs after a power surge.

Safety: Unplug the cooker and wait for all components to cool. Only perform electrical tests if you are competent with mains‑voltage appliances.

• Visual inspection: Remove the base cover to access the heating element terminals and control PCB. Look for burnt spots, melted connectors, or broken wires.
• Check heater resistance: Disconnect the heater leads and measure resistance across the heating element. A typical value is between 20–60 Ω. An open circuit indicates a failed heater.
• Inspect PCB: Examine the power relay or triac on the control board for cracks, burn marks, or lifted solder pads. Resolder any cracked joints if minor.
• Check internal fuse: Some Sencor boards include a small glass or thermal fuse. Test continuity and replace with the same rating if blown.
• Replace parts: Install a new main heating element if open. If the heater is good but not being powered, replace the control PCB / power relay module.
