No Power / Defective Board: If the machine has no power, the main PCB (the yellow board shown) may be faulty. Common fixes involve replacing the board or addressing cold solder joints.Lid Detection Issues: If the machine won't start or displays a lid-related error (like E2), the magnetic lid sensor or door lock mechanism may have failed.Not Draining or Spinning: This can be caused by a defective drain motor, a blocked drain valve, or an issue with the PCB.
