Possible interpretations of E12 error code:

• Motor error: This seems to be the most common interpretation for E12, suggesting a problem with the motor itself. This could include:
  • Internal motor issues: Worn-out components or internal damage within the motor can cause overheating and trigger the error.
  • Blocked drain: If the drain is clogged, water might not be properly pumped out, leading to motor overload and the error.
  • Overloaded washing machine: An excessive amount of laundry or unbalanced load can put extra strain on the motor, triggering the error.
• Motor control issues: In some models, E12 might signify a problem with how the motor is controlled, including:
  • Faulty wiring: Damage or loose connections in the wiring leading to the motor can disrupt its functionality.
  • Defective motor connection block: The block connecting the motor to the control board might be malfunctioning.
  • Control board malfunction: Less commonly, the error could indicate a problem with the control board itself, misinterpreting signals from the motor or sending faulty commands.
