If your Dacor dishwasher is not drying dishes, the problem is usually tied to the vent system first. A vent that does not open properly can trap hot, moist air inside the tub and leave dishes still wet after the cycle. Next, check the turbidity sensor, since a faulty sensor can keep the dishwasher from moving into the drying portion of the cycle. If your Dacor dishwasher is not heating to dry, the vent fan motor is another common cause because it helps move moisture out at the end of the wash. After that, inspect the heating element or heating element assembly. If either part has no continuity, the dishwasher will not dry dishes properly. Some models also use a resettable fuse on the element assembly, so that is worth checking before replacing parts. Finally, look over the wire harness for loose connections, damage, or burn marks that could stop voltage from reaching the heater.

01 - Dacor Dishwasher Vent
The vent might not be opening properly. As the dishes are drying, many dishwashers use a vent to let out the hot, steamy air generated during the rinse cycle. If the vent does not open properly, the dishwasher will leave moisture on the dishes. Check the vent to ensure that it is opening properly.

A dishwasher turbidity sensor measures the amount of food particles in the water being circulated through the appliance to help determine how long a wash or rinse cycle should last. Some sensors also incorporate a thermistor to regulate the temperature. If the sensor is faulty, it may prevent the dishwasher from entering the drying cycle.
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. Note that some dishwasher heating elements have a resettable fuse that can trip, preventing voltage from reaching the element to heat it. Pressing the button on the fuse will reset it and restore power to the element

A wire harness allowing voltage to be sent from the dishwasher control board to a heating element could be loose or damaged and unable to provide power to the element. If this happens, the dishwasher may not be able to dry the dishes properly. You should inspect all wire harnesses for loose connections or damage, especially burn marks near the connection points, and replace if necessary.
