Most of the newer washers made in the last 10 - 15 years especially front load washing machines have bearings that help operate the machine. There are also top load washing machines that utilize bearings in the drive system, but is most common in front loaders. The only thing that separates these bearings from the water is a seal. Over time, water seeps behind that seal causing the bearings to rust and grind. This water will eventually start to seep out of your machine sometimes causing greasy or rusty splatters in (front load washer) or under (top load washer) the machine. naprawa pralek katowice
