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 elements is easy to replace.
Timer/ Control
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 heating elements
If your dishwasher is not heating properly, troubleshoot the issue. You can often repair this problem and eliminate service fees.
Incoming Water Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.
Thermostat The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.
Heating Element/Drying Fan
The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.
Additional Concerns
If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon dishes don't usually completely dry. You must towel-dry these items.

Normally it shouldn't! If the heating element is getting warm enough to dry your dishes then it should dry the water off all but the bottom of the dryer. Can you tell if your heating element is working - as in getting your dishes dry? If not, then you might want to do an ohm check of the heating element to make sure that it has opened.
There is a seperate element for the water heater. so likely to be a faulty heater or thermistor which is fastened toi the element
You really need a test meter to determine which part is faulty.
What temp is your water? You may need to set your water heater up a notch. Try running the dishwasher on the "sani rinse" since this heats to 160 and see if they are drier. Is your heating element working? During the dry cycle with the heat dry on I would open the door and put my hand next to the element to see if it seemed hot. Maybe it isn't working. Also did you put Jet Dry in the dispenser?and also if the setting is adjustable you can dial it up a notch or two. I also like the Jet Dry Turbo. It makes my dishes dry completly, even plastics and this is on the no heat dry.
If there is no heat, then the heating element may be bad. You can get the part, and view diagram at partselect website.

Heating element Drying fan Thermostat Heating element
Your dishwasher has an electrical heating element that helps to dry the dishes. If the element is burned out, the dishes won't dry properly, and you need to replace the element.
Drying fan
Many high-priced dishwashers have a small fan that blows air or heated air into the dishwasher to speed up the drying process. If the fan is defective, you need to replace it.
Thermostat
Some dishwashers have a thermostat that monitors the drying temperature. If the thermostat is defective, the heating element may not cycle on or off properly. If that's the problem, you need to replace the thermostat.
