E12 error code appears, cooker beeps and stops; may occur randomly during cooking.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Corrupted firmware settings on main PCB, Voltage spikes causing memory errors, Defective main control board

Safety first: Unplug the cooker.

Factory reset (if supported): Consult the user manual for a reset procedure (often holding specific buttons while plugging in). Perform the reset to reload default parameters.
Stable power: Connect the cooker directly to a wall outlet, avoiding power strips that may cause voltage drops.
Retest multiple programs: Try different cooking modes. If E12 appears across modes, the main PCB is likely faulty.
Board replacement: This error typically requires replacing the main control PCB with a compatible Midea part.
