E6 shows on the display and the cooker will not start any program.

Safety first: Unplug the multicooker. Internal heater and mains wiring carry dangerous voltages. If you are not experienced with electrical repairs, contact a professional.

• Check for obvious damage: Remove the inner pot and inspect the heating plate for burn marks or deformation. A heavily discolored plate may indicate heater failure.
• Access base (advanced users): Remove the bottom cover to inspect the heater wiring. Look for loose spade connectors, burnt wires, or a blown thermal fuse mounted near the heater.
• Reseat connectors: If any heater connectors are loose, firmly reseat them. Do not operate the unit with partially connected or damaged wires.
• Component replacement: If the thermal fuse is open or the heater coil is visibly damaged, replace the main heating element assembly or thermal fuse as a unit, following the service manual.
