Basically, a dishwasher is a robot that cleans and rinses dirty dishes. Humans have to load the dishes, add detergent, set the proper washing cycles, and turn it on, but the dishwasher accomplishes a whole series of functions by itself.

In addition, dishwashers monitor themselves to make sure everything is running properly. A timer (or a small computer) regulates the length of each cycle. A sensor detects the water and air ­temperature to prevent the dishwasher from overheating or damaging your dishes. Another sensor can tell if the water level gets too high and activates the draining function to keep the dishwasher from overflowing. Some dishwashers even have sensors that can detect the dirtiness of the water coming off the dishes. When the water is clear enough, the dishwasher knows the dishes are clean.

Many people who hand wash do so because they believe it is more beneficial for the environment. However, there is evidence that this is simply not true. While old appliances were hogs of electricity and water, the new versions have become substantially more efficient. There have been great strides in recent decades.

How a dishwasher differs from hand washing

When you wash your dishes by hand, the water and soap stays still in the bowl or sink and you move the dishes around as you scrub them with a cloth or a brush. In a dishwasher, the opposite happens: the dishes and cutlery stay still in plastic baskets while pressurized jets of hot water shoot all around them. That means a dishwasher has to be sealed shut all the time it’s operating or the water would fire off in all directions—all over your kitchen floor!

A dishwasher starts its cycle by taking in cold water from a hose connected to the machine. Once a certain amount of water’s sitting inside the bottom of the machine, a heating element starts to warm it up and the element is just a thick metal bar that gets hot when an electric current passes through it, and it gradually heats the water during the first part of the wash cycle. An electric pump takes the warming water and forces it up pipes in the side of the machine, which are connected to two spinning paddles. There’s one paddle, made of metal, underneath the bottom rack of dishes

When water enters the paddles, it makes them spin around much like garden sprinklers. As the paddles rotate, the water emerges from small holes in their upper surface. The paddles make lots of hot spinning jets of water that fire upward onto your dirty plates. (That’s why it’s best to arrange your crockery so the dirty surfaces are facing downward.) The bottom rack and the bottom paddle are nearer to the heating element so the water is much hotter in the lower part of the machine. (That’s why you’ll see some crockery items marked “Top rack dishwasher safe” which means it’s alright to put them in the upper, cooler part of the machine.) After the water hits your dishes and plates, it falls back to the bottom of the machine, where it’s heated up once more by the element and pumped round again for another cycle. Water pumps around the machine for half an hour or so until all the dishes and plates are clean. A sieve at the bottom of the machine catches any large bits of debris (to stop the machine jamming up), while smaller bits (and food remains) simply flush down the drain.

If you are like many other people, dishes are a primary source of procrastination, and you are prone to letting them pile up. Not only does this make them harder to clean, but it can also lead to a serious source of stress.

A dishwasher makes it easier to relieve this stress by keeping things spotless and out of the sink. Even if you have a few dirty items, they can be easily stowed away in your unit until time for the next cleaning cycle rather than mounting into a menacing pile.

Automatic dishwashers vary in the design of their washing systems (or the means by which water is distributed). Some have a single water source while others may have several water sources. Water is distributed in dishwashers by spray arms or spray towers (or in the case of some older models by an impeller). The design of the spray arms or towers may differ in size, shape, and placement in the dishwasher, or in the number, size, and location of their water ports (holes through which water is forced). All of the washing systems do a good job, but those with fewer water sources require greater care in loading the dishes to prevent blocking the washing action to various parts of the machine, especially the corners.

With all that being said, you can find here below some of the best decent dish washers for home use that can currently be purchased on Amazon.
