The part(s) or condition(s) listed below for the symptom Dishwasher not drying dishes are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
Some dishwashers use a vent fan motor to help dry the dishes at the end of the cycle. If the fan motor is not working, the dishwasher won’t dry the dishes properly. To determine if the fan motor has failed, test the motor for continuity. Also, try turning the fan blade by hand to ensure that it spins freely. If the fan motor has burned out or the fan blade won’t turn smoothly, replace the vent fan motor.
Some dishwashers use a heating element to heat the dishwasher during the drying cycle. If the heating element has failed, the dishwasher won’t dry dishes properly. To determine if the heating element has burned out, use a multimeter to test it for continuity. If the heating element does not have continuity, replace it.
