Bosch Washer - Er:10 Error Code

The motor is not rotating when commanded.

Meaning

The motor is not rotating when commanded.

The Bosch Er:10 error code indicates that the washer attempted to rotate the drum but detected no motor movement. On legacy Bosch washers, the control module monitors motor speed feedback; if the drum does not begin to turn within a defined time window, Er:10 is triggered. This can be caused by a seized drum, broken or slipped drive belt, worn carbon brushes, a failed motor, or a defective motor control module. Because many older Bosch models use brush motors and belt drives, mechanical wear is a common root cause of Er:10.
