Bosch Washer - Er:01 Error Code

The washer door is open or not detected as closed.

Meaning

The washer door is open or not detected as closed.

The Bosch Er:01 error code indicates that the washer door is not fully closed or the control module cannot confirm the closed position. Older Bosch washers use a mechanical door interlock system that must engage before the wash cycle begins. If the latch is obstructed, worn, or electrically faulty, the washer displays Er:01 and prevents operation for safety.

Symptoms

  • Washer will not start
  • Door does not click when closed
  • Er:01 appears immediately after pressing Start
  • Washer beeps repeatedly

Causes

  • Door not fully closed
  • Obstructed latch mechanism
  • Faulty door lock switch
  • Loose wiring to the interlock
🔧

Step-by-Step Fixes

  • Firmly close the door and try again.
  • Inspect the latch for debris or clothing fibers.
  • Reset the washer by unplugging it for 5 minutes.
  • Check the door lock wiring if accessible.
⚠️

Safety Notes

  • Never force the door closed—this can damage the latch.
