E7 error appears and the display may flicker or reset; cooker may shut off unexpectedly.

Safety first: Unplug the cooker before inspecting the cord or internal components.

• Check power source: Plug the multicooker directly into a properly grounded wall outlet. Avoid extension cords or power strips, which can cause voltage drop.
• Test a different outlet: Move the cooker to another circuit in the home to rule out a weak or overloaded circuit.
• Inspect power cord and plug: Look for bent prongs, heat discoloration, or cuts in the cord. Gently wiggle the plug in the outlet while the unit is on; if the display flickers, the outlet or plug may be faulty.
• Internal inspection (advanced): With the unit unplugged, remove the bottom cover and check the main power connector from the cord to the control board. Ensure it is fully seated and not burned.
• Persistent E7: If the error occurs on multiple outlets with a good cord, the internal power supply on the control board may be failing. Replacement of the main control board is recommended via a qualified technician.
