Most people have a washing machine and have experienced a break-down in that machine at some time or another. Very often it is not until something breaks down that we really appreciate the convenience the machine affords us. Having to wash clothes by hand like grandmother did will soon send you scurrying for the phone and the spare parts manufacturer for your 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.
