Bosch Washer - Er:11 Error Code

The motor reversing relay test failed.

Meaning

The motor reversing relay test failed.

The Bosch Er:11 error code indicates that the washer’s control module attempted to test the reversing relay—responsible for switching drum rotation direction—but detected an electrical or mechanical failure. Older Bosch washers rely on relays to alternate between clockwise and counterclockwise drum movement. If the relay sticks, fails to energize, or sends invalid feedback, the washer triggers Er:11 to prevent motor damage.

Symptoms

  • Drum rotates only in one direction
  • Washer stops mid-cycle with Er:11
  • Jerky or inconsistent drum movement

Causes

  • Stuck reversing relay
  • Faulty motor control board
  • Loose wiring to the relay
  • Motor winding issues
🔧

Step-by-Step Fixes

  • Reset the washer by unplugging it for 5 minutes.
  • Inspect wiring to the motor control board.
  • Test the reversing relay for proper switching.
  • Replace the control board if the relay is defective.
⚠️
