Dishwashers dry dishes in several ways: with an electric coil that heats the air, a fan that blows hot air around, an increase in water temperature near the end of a cycle—or a combination of all these methods.
Manufacturers continue to offer potential solutions, including doors that automatically pop open near the end of the cycle so that moisture can escape.
The latest involves embedding the interior walls with crystals that heat up when wet to boost the drying cycle. The results, however, speak for themselves, so be sure to check out our dishwasher ratings for the models that excel at drying.
For more on dishwashers, see our dishwasher buying guide. Allow space between dishes. The idea is to improve the circulation of the water and air, which improves drying.
Use a rinse aid. It prevents spotting and enhances drying. It helps to have an assistant shine a flashlight onto your work area. Unscrew and remove the bottom panel with a Phillips screwdriver, then check inside the access area for two small metal terminals poking down from the heating element up above in the dishwasher tub. Each terminal will have a wire attached to it with a slip connector. Gently pull the connectors down and off the terminals, removing the wires.
If it malfunctions, however, it can shut the heating element off before the dishes are dry. Before getting started, unplug the dishwasher and then remove the bottom panel by unscrewing it with a Phillips screwdriver. Look inside the access area underneath the dishwasher tub for the high-limit thermostat—a silvery disk roughly the size of a quarter towards the right side of the tub.
Slip off the two wires connected to it, and then unclip the thermostat, or use your screwdriver to remove the screws holding it in place, and remove the thermostat from the dishwasher. Touch the two probes of the multitester to the terminals on the high-limit thermostat. While at room temperature, the reading should be at infinite resistance. Now, hold the thermostat near a hot lightbulb or space heater and check the readings again.
The needle should now show zero. If you get some other readings, your high-limit thermostat is faulty and needs to be replaced. This is a job best carried out by a professional appliance repairperson. Improve this answer. Community Bot 1. Some newer dishwashers pop the door open at the end of the cycle and leave the heater running for a bit. I'm not really adding anything to this answer other than it's a valid approach that we can take advantage of.
I grab the entire rack and give it a shake instead of fussing with shaking individual items. Only works if nothing will break when you do this! Tussle the Tupperware, shake both drawers and then pull them all the way out to finish drying.
Don't open the door all the way. Open it a little, shake the top rack vigorously, then leave the top rack pulled out a little so the door is ajar. This will let steam pour out while not cooling the inside as fast as having the door fully open. The darn good shake of the top rack also helps if there are hollows on the bottoms of mugs that have water in them.
Show 2 more comments. Hydrophobic surfaces also explain why non stick pan's can have beads of water on the inside while the outside is dry at the end of the cycle. ChrisH, on the other hand, the hydrophobic coating of non-stick pans also means you can dry them with a quick shake. Plastics aren't hydrophobic enough for that to work.
This answer could be improved a lot if you actually explained the thermal issues as well. As it stands it seems very incomplete though very interesting. If this answer had both parts it would be a very complete and excellent answer. Rubiksmoose yeah, I actually intended this answer to be more of a supplement to Duarte Farrajota Ramos'.
Didn't expect it to outperform that in the votes Some options to help in no particular order: Use a rinse aid.
This would be my first suggestion Rinse aids are designed to coat dishes and then repel water. It makes drying a snap. The lack of splotching is secondary to me. Use the heat dry setting on your dishwasher. If it has it and it works Unload the bottom first can help prevent the water on the upper racks spilling onto the lower dishes.
Load dishes carefully. Make sure when loading the dishwasher you aren't placing anything in such a way that it pools water. Also packing things tight so they don't shift too much and then pool water. Duarte Farrajota Ramos 1, 11 11 silver badges 19 19 bronze badges.

Your suggestion to use a rinse-aid directly contradicts leftaroundabout's answer, where he suggests that repelling water is the problem. Martin, actually a rinse-aid might help the water on a plastic in the dishwasher not stick to itself so much inside the droplets that form , helping it spread out and dry up.
I can confirm rinse aid really helps. We just got a new dishwasher recently and noticed this issue and not just on plastics, everything was coming out wet. Having never bothered with rinse aid before we decided to give it a go and now there is hardly any water left on items.
Plastic does still gather some droplets but nowhere near as bad. Another confirmation on rinse aids: I got plagued by wet plastic for a long time, but just changed the rinse-aid recently, with a great effect: If it doesn't work for you yet , try a different one. It's not perfect, but a lot better. I won't name the brands here, as they'll likely be very different in different areas of the world. Note: I'm using basic detergent tabs and liquid extra-rinse-aid that the machine adds late in the cycle, rather than the features-in-one-tab cleaners that apparently include little gnomes scrubbing and drying your dishes.
