Modern dishwashers effectively use several drying methods to ensure that water is removed at the end of the wash cycle. Most are so clever that often simple changes in use and care can improve performance when the dishwasher leaves dishes damp.
Some dishwashers use heated air or other drying functions to dry the dishes faster after washing. Sometimes dishwashers require you to manually activate the Warm Dry option. Please note that even in dishwashers that are set to dry by default for normal wash cycles, the quick wash or quick wash settings will not include a hot dry cycle to save time, which means you are more likely to have damp dishes.
If you think your dishwasher is leaving the dishes damp, make sure all drying functions are on before starting the wash cycle. To improve the drying performance of your dishwasher, try adding rinse aid to the rinse compartment of the dishwasher before each wash cycle. Some dishwashers have a “power dry” feature that lengthens the drying time, but it should help the water evaporate more quickly so you have less to do.
If your dishwasher has a condensation drying function and uses a lot of plastic, it is almost impossible to dry it completely. Although thermal drying can dry your tableware well, the dishwasher itself may have difficulty drying them completely. If the washing cycle has just stopped, turning on the dishwasher, even if the correct tableware is picked up very quickly, will make the entire load wet.
Sometimes, a large amount of plastic products may be another reason why a dishwasher cannot dry the dishes. Not only can plastics not be flushed with hot water to retain enough heat to make condensation drying work, but they are also very light and can be rolled and moved during the washing cycle.
