If your Dishwasher is not Drying Properly check the following
This is the most common reason why your dishwasher is not drying. To check this remove the toe kick, remove one wire from heating element and check ohm reading. Compare the reading to the tech sheet or service manual. If it has no continuity at all replace the element. Make sure the element is getting power. To do this connect voltmeter to each lead of the heating element then select a dry cycle you should have 120 volts if not the problem is in the control. If it does have power and does not heat up replace the element. The heating element is easy to replace.
This is not as common as the heater but can fail. To check this select a dry cycle and check to see if the heating element has power if it does not replace the control. If the element does have power and does not heat up replace the heating element.
