Bosch Dryer Error E11 — What It Means & How to Fix It

What Does This Error Mean?

Error E11 means the drum motor has stopped working or is not running at the correct speed. The drum motor turns the drum during the drying cycle — without it, clothes cannot tumble and the dryer shuts down. E11 is a hardware fault that requires a technician to diagnose and likely replace the drum motor.

Common Causes

Drum motor has burned out or seized due to age or overloading
Drive belt connecting the motor to the drum has snapped
Foreign object has jammed between the drum and the dryer housing
Motor capacitor has failed, preventing the motor from starting
Control board has stopped sending the correct start signal to the drum motor

How to Fix It

Unplug the dryer from the power socket immediately and do not attempt to restart it.

Forcing a dryer cycle with a failed drum motor can overheat the motor windings and cause a fire hazard.
Open the dryer door and try rotating the drum by hand — it should spin freely with mild resistance.

If the drum will not rotate at all, a foreign object jam or broken belt is preventing it from moving.
Check for any foreign objects in the drum and around the drum lip that might have caused a jam.

Coins, underwire from bras, and small items can lodge between the drum and the housing and stop the drum.
Listen when you start the dryer — a humming motor with no drum movement suggests a broken belt or seized drum bearings.

The belt runs around the drum and a pulley — it can snap without warning.
Check the dryer's warranty status — Bosch's standard warranty covers motor faults.

Contact Bosch customer service with your model number to arrange a warranty repair if applicable.
Contact Bosch service or a qualified appliance engineer to diagnose and repair E11.

Ask the technician to check the drive belt first — it is cheaper than a full motor replacement.

When to Call a Professional

E11 is a critical fault that always requires a technician — the drum motor or drive belt needs replacement. A technician can quickly confirm whether the motor, belt, or a blockage is the cause. Drum motor replacement costs $150–$400 depending on the model — compare against replacement if the dryer is old.

Frequently Asked Questions

What is the difference between Bosch dryer E08 (fan motor) and E11 (drum motor)?

E08 relates to the fan that circulates air through the dryer — you will feel no airflow from the exhaust. E11 relates to the drum motor — the drum stops turning but the fan may still run. Both require professional repair, but they are separate motors on different circuits.

Can a broken drive belt cause Bosch dryer E11?

Yes — a snapped drive belt causes the drum to stop spinning, which the control board detects as a motor fault. The motor runs but the drum does not move — E11 is triggered because the expected drum rotation is not detected. A drive belt is a cheap part ($15–$40) and is one of the most common dryer repairs.

How can I prevent the Bosch dryer drum motor from failing?

Avoid overloading the drum — exceeding the rated load strains the motor and belt. Clean the condenser and filter regularly — restricted airflow increases motor run time and heat stress. Do not run back-to-back cycles for extended periods without a short cool-down.
