Safe first steps, before the call. Nothing here needs a tool.
Note what the noise sounds like and when it happens, then stop the washer and switch off its breaker, or unplug it if the plug is dry and you can reach it without moving the washer.
Take a photo of the washer and any code on the display, without opening anything.

Everything else about this problem
Is it an emergency?
Is a loud noise from a Bosch washer an emergency?
Usually not an emergency. A grinding, rattling or humming that has just started most often comes from a fan, motor, belt or loose panel. Stop using it and cut the power if the noise comes with a burning smell, smoke or sparks.
Symptoms & causes
Your Bosch washer might be emitting grinding, banging, or squealing noises, particularly during the spin or agitation cycles, indicating internal mechanical stress. These sounds often point to issues like worn drum bearings, loose counterweights, or foreign objects trapped between the drum and tub. For Bosch models, failing shock absorbers or a deteriorating drive belt are also common culprits behind excessive noise.
Tools & parts
You will need basic hand tools such as a socket set, screwdrivers (Phillips and flathead), and possibly a spanner wrench for accessing internal components. Common replacement parts like Bosch drum bearings or shock absorbers may be needed. A multimeter for electrical tests and a flashlight are also highly recommended for thorough inspection.
Safety first
Always disconnect the washer from its electrical power source by unplugging it before beginning any inspection or repair to prevent electrical shock. Turn off the water supply valves to the washer to avoid leaks or flooding during component removal. Be cautious of sharp edges inside the machine and heavy components like the motor or concrete counterweights, which can cause injury if not handled properly.
When to call a pro
If the noise originates from a sealed outer tub bearing, which is common in some Bosch models, a professional technician is often required as the entire tub assembly may need replacement, a complex and costly repair. Issues with the main drive motor or the control board, which can manifest as unusual noises or operational failures, typically require specialized testing tools and expertise. Furthermore, if you suspect a major structural component failure or are uncomfortable with disassembling the appliance, calling a certified Bosch technician is advisable to ensure a safe and correct repair.
Questions people ask
What causes a Bosch washer to make a grinding noise?
A grinding noise in a Bosch washer often indicates worn-out drum bearings, which support the spinning drum and degrade over time. It could also be caused by a foreign object, like a coin or bra wire, lodged between the inner and outer tubs.
Why is my Bosch washer banging during the spin cycle?
Banging during the spin cycle is frequently due to an unbalanced load, so always ensure clothes are evenly distributed. If the load is balanced, worn shock absorbers or loose counterweights on the tub could be failing to dampen vibrations effectively.
Can I fix a noisy Bosch washer myself?
Many common noise issues, such as foreign objects, loose components, or even replacing drive belts and shock absorbers, are manageable for a DIY enthusiast. However, complex repairs like replacing sealed tub bearings or checking motor control board failures typically require professional expertise and specialized tools.
