Powder Is Not Dissolving in a Samsung Dishwasher
Samsung dishwashers use rotating spray jets to clean dishes. For heavily soiled items, some Samsung dishwashers have a "StormWash" feature, a wheel near the bottom rack that scours difficult-to-clean items. In addition, Samsung dishwashers have several wash cycles and a National Sanitation Foundation-certified sanitizing cycle. If you notice that the detergent powder is not dissolving when you run your Samsung dishwasher, you're experiencing an issue common to dishwashers. Investigate to resolve the problem.
Loading the Dishwasher
When loading your Samsung dishwasher, set smaller dishes in the top rack and larger dishes in the bottom rack. Place items facing down for the best wash results, and do not nest items together, as this reduces the overall water flow. Once the dishwasher is loaded, turn the nozzles on the spray arms to make sure they are not blocked by dishes, and inspect the detergent dispenser to make sure it is not blocked either. If dishes are loaded so that the dispenser cannot open, the detergent cannot dissolve into the wash water.
Over time, the detergent dispenser may get dirty or may cause the detergent to clump together due to moisture in the cup. If the powder is sticking in the dispenser and is not dissolving completely during the wash cycle, use a clean cloth to wipe out the dispenser cup and remove any clumps or debris.
Too Much Detergent
Add the recommended amount of powdered automatic dishwasher detergent to the dispenser cup. Samsung recommends the use of 0.5 oz. of detergent in the main wash dispenser cup for most dishes and soil levels, and 0.7 oz. of detergent in the main wash dispenser and 0.2 oz. in the prewash dispenser for heavily soiled items or pots and pans. The use of too much detergent may leave detergent in the cup that does not completely dissolve during the cycle.
Powdered detergent that is more than eight or nine months old is likely to clump together and stick in the dispenser, making it difficult to dissolve. Use fresh detergent and store the powdered detergent in a cool, dry place to prevent heat or moisture from affecting the detergent.
The water that enters the dishwasher should reach 120 degrees Fahrenheit or more in order to properly dissolve the detergent and clean the dishes. Run water at the kitchen sink until it's hot just before starting the dishwasher to increase the temperature of the water as it enters the unit. Consider increasing the water temperature at the water heater if necessary.
