Dishwasher Not Drying? Rinse Aid, Settings and Real Fixes

Published 2026-10-19 · Last reviewed 2026-10-19 · Checked against manufacturer sources

Quick answer

An empty rinse aid dispenser is the most common reason dishes come out wet, followed by a dry setting that uses no heat. Refill the rinse aid, choose Heated Dry or Extended Dry, and make sure the hot water reaches the dishwasher at 120°F (49°C) or more. Some wet plastic is normal, especially on condensation-dry models.

Safety first: Turn off the dishwasher's breaker before reaching near the heating element or removing the kick panel, and let the element cool for at least 20 minutes after a cycle. Don't place plastic on or near an exposed element.

Refill the rinse aid and turn the setting up

Rinse aid makes water sheet off dishes instead of beading up, and GE calls it the most important requirement for dry dishes. Without it, you get droplets on every glass and puddles on top of every mug.

Open the door all the way and find the dispenser next to the detergent cup. Whirlpool's dispensers hold about 5 oz (150 mL), which lasts 1 to 3 months, and a clear indicator window means it's empty. Fill it to the line and wipe up any spill so it doesn't foam on the next cycle.

If you have hard water or still see spots, raise the dispenser setting one step and give it a few loads before you judge. Whirlpool notes that just enough works better than too much.

Choose a dry option that actually uses heat

Many dishwashers default to an energy-saving or air-dry setting that doesn't heat at all. Look for Heated Dry, Heat Dry, Pro Dry, Power Dry, Dry Boost or Extended Dry on your control panel and turn it on. Whirlpool says Extended Dry adds 15 minutes and helps with big loads.

Some Whirlpool and LG models also have an auto-open or Door Open Dry feature that cracks the door a few inches at the end of the cycle to let steam out. If yours has it, turn it on so the steam escapes instead of settling back on the dishes. LG shows F37 if the auto-open door doesn't work.

Get hot water to the dishwasher

Dishes dry from the heat they hold after the final rinse. Cold dishes stay wet. GE and Whirlpool both want the hot water supply at 120°F (49°C) or above, and GE gives 150°F (66°C) as the upper limit.

To check, run the hot faucet closest to the dishwasher for a minute, fill a glass and put a candy or meat thermometer in it. If it reads low, the water heater may be turned down. Before starting a load, run the kitchen hot tap for 15 to 30 seconds so the dishwasher fills with hot water instead of the cold water sitting in the pipe. GE dishwashers can show C6 when the incoming water is too cold.

Load so water can run off

Every cup, bowl and pot should sit at an angle with its open side facing down. Water collects in anything that sits flat or face up, and no drying system can evaporate a quarter cup of water in a mug base.

Whirlpool recommends placing glasses between the tines rather than over them, since a tine poking into a glass leaves drips. Don't nest bowls or crowd the racks so tightly that air can't move between items.

When the cycle ends, unload the bottom rack first. GE's tip: the water that pools on top of upturned mugs on the upper rack spills onto the dry dishes below if you pull the top rack out first.

Why plastics stay wet

Plastic doesn't hold heat the way glass and ceramic do. It cools quickly after the rinse, so the water on it doesn't evaporate. GE and Whirlpool both say some droplets on plastic are normal.

Put plastic cups and containers on the top rack (Whirlpool suggests the third rack if you have one). On models with an exposed heating element in the tub floor, keep plastic off the lower rack, where the element can warp it. A quick towel wipe is often the practical answer. Lightweight items that flip over during the wash also come out full of water, so wedge them in place.

Condensation-dry dishwashers work differently

Bosch dishwashers, like many European-designed machines, have no heating element in the bottom of the tub. Bosch explains how theirs dry: the final rinse heats the dishes, the stainless steel tub cools faster than the load, and the moist air condenses on the tub walls and drains away. It's efficient, and plastics can go on the lower rack without melting, but the whole thing depends on hot dishes and rinse aid.

On a condensation-dry dishwasher you'll often see beads of water on the inside of the door and tub walls. Since Bosch's design relies on moisture condensing on the tub, those drops aren't a fault. For drier results, use the Extra Dry option that Bosch offers on select models. Bosch CrystalDry models add a zeolite drying system and show E07 or E10 when it faults.

Test the heating element and dry system

If you've done everything above and the dishes are still wet and cool to the touch, the heat may not be working. Whirlpool's test: run a Sanitize cycle if your model has one. A steady Sanitize light at the end means the element heated. A blinking light means it didn't reach temperature. Without Sanitize, run a one-hour wash with Heat Dry on. The cycle should run about 90 minutes and the dishes should feel warm.

Heating faults show up as codes on many models: LG HE, Samsung HC or HE, Whirlpool and KitchenAid F4E2 or F4E3, Frigidaire i60 and Bosch E09. LG dishwashers with a drying fan show F31 when the fan stops and F35 for a dry heater temperature fault.

Element and dry fan replacement involves wiring at the bottom of the tub, often from underneath. If you aren't comfortable working on it unplugged with a meter, this is the point to book a technician.

When to call a professional

Schedule service if the Sanitize light blinks, the dishes come out cool after a heated dry cycle, or a heating or dry fan code appears. A technician can test the heating element, the thermostat or thermistor, and the control that powers them.
