Those that want to consider the environmental impact can go "green" with a miniature hand-operated version. They are inexpensive and use very little soap and water, and no electricity. If you want the absolute king of the hill when it comes to engineering and performance, treat yourself a Miele washing machine.
A machine's brand name does not mean all its parts are composed of the same brand. Parts and pieces may have built through other brands. These other brands should still be compatible to the actual unit though. As mentioned on the paragraph above, choose what is best according to most users. You can trust the opinion of experts and professionals with repairs.
