Why Is My Bosch Washing Machine Making Loud Noises?
Pause safely, redistribute the load and check levelling and visible objects according to the exact manual (about 5–15 minutes).
Fault description
Bosch lists an unbalanced or overloaded load, incorrect levelling, transit bolts and accessible foreign objects among common causes of unusual washer noise.
Pause safely, redistribute the load and check levelling and visible objects according to the exact manual. Always follow the manual for the exact E-Nr and do not remove panels or test internal parts.
Causes
- Unbalanced or overloaded laundry — Heavy items can gather on one side and create banging during spin.
- Washer not level or surface unstable — All feet must stand firmly and lock nuts must be secured as the installation manual describes.
- Transit bolts on a new installation — Transport restraints left fitted can cause severe noise and damage.
- Foreign object or internal fault — Accessible objects may rattle; persistent grinding, scraping or knocking needs service.
