E7 appears and the cooker does not heat or stops shortly after starting.

Safety first: Unplug the cooker and allow it to cool. This fault involves mains voltage; proceed only if you are qualified.

• Visual inspection: Turn the cooker over and inspect the base for signs of burning, melted plastic, or a burnt smell, which may indicate a failed heater or thermal fuse.
• Check power outlet: Test the outlet with another appliance to rule out supply issues.
• Internal check (advanced): Remove the bottom cover to access the heating element terminals and thermal fuse. Look for loose connectors or obvious damage.
• Continuity testing: Using a multimeter (with the unit unplugged), check continuity across the heating element and thermal fuse. An open reading indicates a failed component that must be replaced.
• Do not bypass safety devices: Never bypass the thermal fuse or safety thermostat; replace with the correct Zavor-rated part.
• If unsure: Because this repair involves high voltage and safety-critical parts, contact a professional technician.
