The Association of Home Appliance Manufacturers estimates a dishwasher will save an average user 4 hours of hand washing per week. Maytag Appliances recommends consumers look at more than the price when purchasing a dishwasher. This allows the user to start the appliance with just a touch of a button. The Wash System Maytag recommends buyers look for a three-level wash system, with an upper wash arm, lower wash arm, and a center wash tower. The size and number of spray arm holes can be an indication of the cleaning effectiveness.
Smaller holes can create a finer, more vigorous spray for greater scrubbing action.
It is important the dishwasher keeps food particles from redepositing on clean dishes. The best way to do so is by filtering the water. A system that filters 100 percent of the water through a very fine mesh is very effective. Some units have a secondary filter using an even finer mesh, for even better effectiveness. Internal Food Disposer To improve performance and eliminate the need for prewashing, some dishwashers have a disposer to chop food into tiny particles, which are removed with the drain water.
