* '''Wash Tiers'''
** The places that water sprays from are known as '''wash tiers''' or''' wash levels'''.
** The better dishwashers have three; discount "builder's models" may only have one.
** More tiers are always better. Unless you plan to use your dishwasher for only very light cleaning (like in a wet bar), you definitely want at least two tiers. Three or more is the standard number in most of the top-performing dishwashers.
** If your kitchen opens up to the living or dining room, choosing a '''ConsumerSearch'''''', many users complained that third racks just made it harder to load the dishwasher.
* '''Efficiency Rating'''
** Check Energy Star ratings to save money on electricity and water.
** More efficient models may cost a little extra, but the '''savings''' on your energy bill will quickly make the additional cost worthwhile.
** Efficient models are also more environmentally friendly.
* '''Heavy-duty disposal options'''
** Food-grinder/garbage disposal.
** Some dishwashers have built-in solid food disposals; other models require you to clean the filter every few weeks.
* '''Warranty '''and in-area servicing.
** Dishwashers are usually pretty reliable, but a warranty is always a good thing to have.
