Samsung Dishwasher Is Not Drying

Meredith Jameson

Samsung dishwashers are some of the quietest in their class, according to the Samsung website, and the dishwashers offer options like adjustable racks, a steel tub, Energy Star rating, rotating spray jets, several wash cycles, and a large-capacity tub.

Problems can occur with just about any home appliance, however, and if the Samsung dishwasher is not drying, owners may be left trying to troubleshoot the problem.

Cold Water

If the water entering the dishwasher is very cold, or hot water is not used in the wash cycle, dishes may not dry completely because it takes longer to dry cold, wet dishes. Check to make sure the dishwasher is connected to a hot water supply valve and run the hot water at the nearest sink. Check the hot water temperature with a candy thermometer to see if it reaches at least 120 degrees Fahrenheit. If the water does not warm sufficiently, raise the temperature on the home hot water heater or contact a plumber for assistance.

Rinse Aid

The Samsung dishwasher is designed to use rinse aid detergent, which helps remove water from the dishes and improves drying performance. Rinse aid detergent can be purchased in most grocery stores, drug stores or hardware stores. Pour the rinse aid detergent into the rinse aid compartment on the dishwasher door until full. If any detergent spills, wipe it up before running the dishwasher. Spilled rinse aid detergent can foam excessively, causing leaks.


If the dishwasher is too full, the air flow is limited and dishes may not be able to dry properly. Load dishes with space in-between each dish and face items down towards the center of the tub when possible. Avoid nesting items inside each other, as the dishes may not get clean or dry. Note that some items, such as plastic pieces, may remain wet regardless of whether the dishwasher was overloaded or not and can be wiped clean with a towel.

Cycle Selection

The Samsung dishwasher has an “Air Only” dry cycle, which reduces energy use and allows the dishes to air dry instead of blowing warm or hot air onto the dishes to dry them. The air dry cycle may take longer to complete than a heated dry cycle and items may not be completely dry at the end. Select heated dry for faster drying and consider choosing the “Sanitize” option for faster heated drying.
