9 Reason Behind Dryer Grinding Noise

Rollers and Shaft. The drum roller and shaft work in coordination with each other. When one is broken, it will affect the other. One of the causes of dryer noise is the loose bearing in the roller. In the dryer, the shaft won't spin and will cause a grinding noise while it makes an effort to move when the roller and shaft are broken.

Maytag Washer Making Grinding Noise During Spin Cycle

1. Load Distribution. If you put in clothes in your Maytag washer and run the spin cycle and it starts making grinding noises then the most common reason we believe can be the uneven distribution of the load. So, don't rush, wait and check if you have accidentally put all the clothes on a single side. If this is the issue then evenly ...
