Even your average machine from Maytag, Whirlpool, GE and many of the other common brands eventually will balk at the neglect. Many times, these are basic repair issues. Replacing a band or pump, for example, is pretty easy to do. A good deal of the problems don't even require repair - a quick troubleshooting, like taking a kink out of a hose is all they need at times. If it is a little more problematic, affordable washing machine parts can be purchased for these same aforementioned brands on several internet sites.
Once you know what part you need you can then go ahead and buy it. This need not be difficult if you have a computer and Internet connection. There are many spare parts stores online; all you need is the name and model number of the part to order it and it will usually arrive on the doorstep within a few days.
