Installing a dishwasher can cut down greatly on the time you spend cleaning up after a meal, and replacing an old dishwasher can be a very smart move since today's models are far more energy-efficient than those of yesteryear. However, shopping for a dishwasher can be a confusing experience as you try to find the best value in a sea of competing products. With all the added features available on modern dishwashers, it's a good idea to take stock of what you need from your dishwasher and what you don't.
In addition to the dishwasher's capacity, the number of racks and its ability to spray water throughout its interior, you will also need to think about jet systems, drying systems and energy efficiency when shopping for a dishwasher.
Your dishwasher's jet system is what determines the appliance's ability to deliver water from all angles, ensuring your dishes get as clean as possible. In broad terms, jets come in two types: static and mobile. Static jets won't move but tend to be more powerful with broader spray areas, while mobile jets can get into every nook and cranny to make sure nothing is left unwashed. Jets can be configured in arms or centrally: most dishwashers designed for residential use have either one or three arms, or a central hub from which water sprays out in all directions.
If you want to save energy and money, air-drying your dishes will work just fine. However, if you want the convenience of a built-in dish dryer, you can purchase models that have dry cycles in addition to wash cycles.
To make sure you're purchasing an environmentally responsible product, look for dishwashers bearing the Energy Star seal. This ensures that they use 10 to 50 percent less energy than the maximum amount allowed by government standards.
