Why is my washing machine making strange noises?

All washing machines make low level noise during a wash programme which is completely normal and not a cause for concern. However, there are some loud noises which may indicate there is an issue with the washing machine and they need to be solved promptly.

Squealing, screeching, banging, knocking, bumping, scratching, and rumbling are some of the more common noises that can come from a faulty washing machine. If your washing machine is making strange and loud noises, there are 3 simple steps you can take to resolve these quickly and easily without the need for a Bosch engineer to repair your washing machine.

Issues with the washing machine vibrating and moving across the floor can be attributed to the surface on which it is installed. Wooden floors are particularly unsuitable. Ideally you should install your washing machine in the corner of a room on a hard surface. If necessary, screw a water-resistant wooden board with a minimum thickness of 30mm and place the appliance on the board.

Check that the transportation bolts have been removed from the back of your washing machine. If they have not, you should remove these immediately and replace them with the blanks that came with your machine. You can refer to the installation instructions for support. The video on the right shows you how to remove and replace the transit bolts.

Washing machines that are not balanced can result in loud thumping or knocking sounds, especially when operating at high speeds. To remove these loud noises, check the feet to ensure that the washing machine is evenly balanced and resting on a flat surface. Also check that the washing machine is parallel to the ground by using a spirit level. If it is not level, adjust the feet accordingly and tighten them in place. To level your appliance:

• Place a spirit level on the appliance.
• Turn the feet on the appliance until the spirit level is aligned.
• Secure the feet with the lock nuts by following the instructions in the installation guide.
• If the appliance is standing on a base, secure the feet with the clip holders. The clip holders are available as an accessory.
