Error Code Error 11

Error Code 11: Drum Direction Problem

This specific error code, Error 11, signals an internal malfunction related to the electromechanical component responsible for managing the direction in which the wash drum rotates. Essentially, the machine’s control board has detected that it cannot reliably command the motor to switch its direction (forward to reverse, or vice versa) as required during the wash or spin cycle. This often points directly to a fault within the switching mechanism.

Possible Solutions:

• Check the wiring to the relay.

  • The relay in question is an electrical switch, often located on the main electronic control board or a separate motor control board, which handles the high-voltage switching necessary to reverse the polarity of the power sent to the motor, thereby reversing the drum spin direction.
  • Carefully inspect all electrical connections leading directly to and from this relay. Look for loose spade connectors, corroded terminals, or any visible signs of singeing or heat damage on the wiring harness insulation. A loose connection can interrupt the necessary signal or power, mimicking a relay failure. Ensure that the wiring harness plugs are firmly seated in their respective sockets.

• Have the relay checked by a professional. The relay may be defective and need to be replaced.

  • If the wiring appears secure, the relay itself is the next likely point of failure. These components are subject to wear and tear due to the constant thermal and electrical stress of switching high motor loads.
  • A qualified appliance technician will have the necessary diagnostic tools to test the continuity and operational integrity of the relay coils and contacts. If the relay fails these diagnostic checks—meaning it is not physically opening or closing the circuit when energized by the control board—it must be replaced. In many modern appliances, this requires replacing the entire electronic control board, as the relay is often permanently soldered onto it, rather than being a serviceable, plug-in component.

• Contact Bosch or Siemens customer service for further assistance.

  • Because diagnosing and replacing components related to the motor control circuitry often involves working with high voltage and requires specialized knowledge of the specific circuit board layouts for Bosch and Siemens models, it is strongly recommended to seek authorized support if the preliminary wiring check does not resolve the issue.
  • Providing the exact model number to customer service will allow their technicians to reference specific technical bulletins regarding known issues with the Error 11 fault on your appliance variant, ensuring accurate diagnosis and repair procedures.
