Whirlpool dishwashers have a heat dry option. Used in conjunction with a rinse aid, this option will effectively dry dishes after they have been washed. The rinse aid allows water to drain off dishes during the final rinse and prevents pooling. If the heat dry option does not perform as intended, troubleshoot the appliance to determine the problem and correct it.
Check the rinse aid indicator beside the rinse aid dispenser cap. If the indicator window is clear, refill the dispenser. The dishwasher will retain moisture and the heat dry option will not perform properly without rinse aid. Turn the dispenser cap clockwise and lift it up to remove it. Pour rinse aid into the dispenser until the indicator appears full. Place the dispenser cap over the dispenser and turn it counterclockwise to tighten it.
Load the dishes properly so that all dishes can drain after the rinse cycle. Do not overload the dishwasher. Towel-dry plastic dishes because they will not dry completely during the dry cycle.
Select the heated dry option on the dishwasher. The air-dry and energy-saving dry options will not perform as well as the heated dry.
