My dryer hums but the drum does not turn; should I keep trying it?
Quick answer
You don’t need to keep repeating the start attempt: another identical attempt adds little to the information you can give service. Check only that the door is fully closed and the dryer is plugged in. If the drum still will not turn, contact the manufacturer’s support team. Bosch recommends those basic checks and directs users to support if they do not resolve the problem; its guidance does not explain what humming means for your dryer. [S1]
The question, the details, the next step.
A practical checklist
Check that the door is fully closed and the dryer is plugged in.
If the drum still will not turn, contact manufacturer support. [S1]
Do not open the cabinet or attempt belt or motor work.
Write down the setting, sound, drum movement, and basic checks.
Use only details you know; mark uncertain information as unknown.
A few more useful answers
Does a humming sound prove the belt or motor has failed?
No. The supplied Bosch guidance does not specifically address humming or identify a cause for an individual dryer. Report the sound and symptom to support without guessing at a failed part. [S1]
What if the door is closed and the dryer is plugged in, but the drum still will not turn?
Contact manufacturer support. Bosch directs users to support when its basic checks do not resolve a drum that will not spin. [S1]
Should I open the dryer to collect more details?
No. Record what you can observe without opening the cabinet, and ask support what additional information they need.
