Bosch Dryer Error Code E11 — Drum Motor Malfunction
What this means
Error E11 means the drum motor has failed or cannot start. The motor is responsible for rotating the drum. A seized motor, broken winding, or faulty motor start capacitor can cause this error. You may hear a humming sound if the motor is trying to start but cannot.
Step-by-step fix
4 stepsListen for motor sounds
Start the dryer and listen. A humming noise suggests the motor is getting power but cannot turn. Silence means no power is reaching the motor.
Check the belt
A broken drive belt can prevent drum rotation. Some models will not run the motor if belt tension is lost.
Test the motor
Disconnect the motor and test windings with a multimeter for continuity and proper resistance.
Replace the motor
If the motor windings are open or shorted, the motor needs replacement.
When to call a professional
Drum motor replacement requires significant disassembly. Professional service is recommended.
