Drying
The heat inside the dishwasher dries the contents after the final hot rinse. Plastic and non-stick items may not dry properly compared to china and glass, which hold the heat better. Some dishwashers incorporate a fan to improve drying. Older dishwashers with a visible heating element (at the bottom of the wash cabinet, below the bottom basket) may use the heating element to improve drying, however this uses more energy.
North American dishwashers tend to use heat assisted drying via an exposed element. European machines and some high end North American machines use passive methods for drying – a stainless steel interior helps this process and some models use heat exchange technology between the inner and outer skin of the machine to cool the walls of the interior and speed up drying. Most dishwashers feature a drying sensor and as such, a dish-washing cycle is always considered complete when a drying indicator, usually in the form of an illuminated "end" light, or in more modern models on a digital display or audible sound, exhibits to the operator that the washing and drying cycle is now over.
Governmental agencies often recommend air-drying dishes by either disabling or stopping the drying cycle to save energy.

Famous quotes containing the word drying:
“Generally speaking, the political news, whether domestic or foreign, might be written today for the next ten years with sufficient accuracy. Most revolutions in society have not power to interest, still less alarm us; but tell me that our rivers are drying up, or the genus pine dying out in the country, and I might attend.”
—Henry David Thoreau (1817–1862)
“The drying up a single tear has more
Of honest fame than shedding seas of gore.”
—George Gordon Noel Byron (1788–1824)
“Just as petals fall from drying garlands, which you can see aimlessly swimming in wine-bowls are we lovers, who now puff up our chests, but perhaps tomorrow the fateful day will shut us down.”
—Propertius Sextus (c. 50–16 B.C.)
