E6 is displayed and the cooker does not heat or stops mid-cycle.

Safety first: Disconnect from mains before any disassembly. High voltages are present inside.

• External checks: Confirm the wall outlet works by testing another appliance. Check the power cord for visible damage.
• Internal inspection (advanced): Remove the bottom cover. Locate the circular heating element under the inner pot area.
• Check heater connections: Inspect the heater terminals and wiring for discoloration, burning, or loose spade connectors. Tighten or replace damaged connectors as needed.
• Inspect thermal fuse: Many ETA multicookers have a thermal fuse attached to the heating plate. Check for signs of overheating or breakage.

When to call a technician: Measuring heater resistance and replacing the heating element, thermal fuse, or control board involves mains wiring and should be performed by a professional.
