A dishwasher is a device used to automatically dry and clean dishes by heating them to a certain temperature, which usually ranges from about 150 to 170 degrees Fahrenheit. Unlike manual dishwashing, that depends heavily on physical washing to remove soiling, the automatic dishwasher simply cleans by spraying hot air, typically up to about 150 to 170 degrees, at the dishwasher dishes, using lower temperatures for delicate items like glasses. The temperature control allows dishes to dry more quickly, avoiding food sticking and soap build-up on the dishwasher floor. Dishwashers are very common in most homes today. The dishwasher has helped to make dishwashers easier to use and more practical for home use as well.
There are three types of dishwasher: slow, semi-slow and fast. The difference between these three is the speed at which the device heats water to rinse dishes may rua chen. The slowest cycle takes longer to complete while the middle speed is the fastest. A fully loaded dishwasher goes on automatically, but some models require a manual start, a pull down handle and a short spray to begin the rinse cycle.
Racks are containers in the front of dishwashers that hold washed dishes on their sides. A wire rack, called the stand-up rack or the pedestal to rack fits on the left hand side as well as the right side of the appliance and is made from either aluminum or plastic. Wooden racks are often used because they give the dishwasher more counter space on which to sit. They do not protect the dishes as well as any other rack types. The standing rack is the only type that is certified safe for use in public places.
Dishwasher racks, either standing or pedestal, come in two basic varieties: metal and plastic. Metal racks are typically welded and are available in finishes that will match the rest of the house. Plastic tub racks have a universal threading design that threads the tub onto the bars inside the rack, giving the finished rack a neat, professional finish. Plastic injection molding is used to create the look of wooden racks, and may be left unfinished or painted for a more authentic look.
One feature that all dishwashers have, regardless of style, is the ability to add hot and cold water jets. These jets separate and wash separate items in the washing machine, moving them through different stages of cleaning without calling attention to one another. Some dishwashers come with two hot water jets and one cold, while others may have only one hot and one cold option. If the rack has a manual setting, it only calls for hot water when the items are full. This feature can help reduce the risk of scalding when washing dishes with very hot water.
A final consideration in the choice of dishwasher is whether or not there are built-in agitators inside the dishwasher. Some dishwashers have large single stage agitators on the bottom rack. These powerful little gadgets push food out of the dishwasher, helping to clear up lint and soap scum. Other dishwashers have smaller single stage agitators on the top of the bottom rack, with a built-in rotating brush that uses suction to scrub food particles from the bottom of the dishwasher. The best dishwashers have both single and multiple agitators and are able to handle heavy weights. Whether you need a simple system for rinsing off dishes or a more complex system for heavier duty tasks, your dishwasher should have plenty of power.
