For most loads, air dry with rinse aid gets dishes dry enough and saves energy. Heated dry earns its keep when you have plastics in the load or need dishes ready right away, since it adds time and electricity but finishes the job faster. The trade-off is simple: a little more drying power against a little more cost and a small risk to heat-sensitive items. A few habits and a quick troubleshooting pass, covered below, close most of the gap.
TL;DR:
- Consumer Reports testing found plastic hardest to dry; doors that open automatically and desiccant systems improved results.
- Rinse aid, downward angled bowls, clear spacing, and leaving the door open after the cycle help remove moisture without extra heat.
- Heated cycles can damage insulated drinkware, unrated plastics, utensils with wooden handles, and coated cookware; check labels and keep delicate items on the top rack.
- Dishwashers sanitize during the final rinse, not while drying; NSF/ANSI 184 certification requires a 150°F rinse, so heated drying adds no sanitizing benefit.

How heated dry and air dry actually work
Heated dry switches on a heating element, or raises the final rinse temperature, so hot air speeds up evaporation once the wash cycle ends. That extra heat is also extra runtime and extra electricity draw, which is why a heated cycle often takes noticeably longer than one set to air dry. Air dry, sometimes labeled an energy saver setting, skips that heating step and leans on whatever warmth is already in the tub, along with condensation on the cooler door and walls, to pull moisture off the dishes. Some newer machines help that process along with a fan, an auto-open door that vents steam partway through, or a desiccant material that pulls humidity out of the air.
Panel names vary by brand, which causes a lot of the confusion homeowners run into when comparing manuals. Common labels include:
- Heated Dry or Hi-Temp Dry, the active heating setting
- Energy Saver or No-Heat Dry, the passive, non-heated option
- Condensation Dry, a passive method relying on temperature difference at the tub walls
- Auto Air or Auto Open Door, a vented hybrid approach
- CrystalDry or similar branded terms for zeolite-assisted drying
Checking your own control panel or manual against this list avoids a lot of guesswork before you change any settings.
Which setting dries which materials better
Material matters more than most people expect. Glass and ceramic hold and release heat predictably, so they tend to dry fine on an air-only setting, especially with rinse aid in the mix. Plastic is a different story. It cools faster than glass or stainless steel, so condensation keeps forming on its surface well after the cycle ends, leaving puddles in bowls and lids even after everything else is bone dry.
Plastic is notably one of the hardest items to dry in lab testing, and Consumer Reports testing found air dry alone was the least effective method for it, while auto-open doors and desiccant or zeolite systems noticeably improved results. A separate lab bulletin from Consumer Reports reported that an auto-open door produced the most consistent drying in a limited sample of machines tested.
In short:
- Glass and ceramic: air dry plus rinse aid is usually enough
- Plastic containers and lids: heated dry, auto-open, or a desiccant system perform better
- Stainless steel tubs: help passive drying along by staying warm longer than plastic tubs do
Energy and cost trade-offs of heated dry
Water heating is the single biggest energy draw in a dishwasher cycle, according to DOE’s technical analysis of dishwasher energy use, but the drying phase and general machine operation still add a real, non-trivial share on top of that. Switching on heated dry stretches the cycle and runs the heating element for longer, and that adds up over a year of near-daily use into a noticeable bump in electricity consumption.
Whether that bump is worth paying comes down to a few personal factors: how often you run the dishwasher, your local electricity rate, and whether rinse aid or an auto-open door gets you comparable results without the extra heat. For many households, reserving heated dry for plastics-heavy loads or nights you need dishes back in the cabinet fast is the more sensible default.
What heat can damage, and the sanitizing myth
High drying heat is not universally friendly to everything in the rack. Insulated mugs and tumblers, certain plastics not rated for dishwasher use, wood-handled utensils, and some non-stick or coated cookware can warp, discolor, or break down under repeated heat exposure. Checking the label before you run a heated cycle is worth the ten seconds it takes.
A few practical placement rules help:
- Keep insulated drinkware and delicate plastics on the top rack, farther from the heating element
- Follow manufacturer labels for anything marked “top rack only” or “hand wash recommended”
- Angle cups and bowls downward so they do not pool water during either drying method
One common mix-up is worth clearing up directly: sanitizing and drying are not the same process. Certification under NSF/ANSI 184 requires a final rinse at 150°F, and that high-temperature rinse, not the drying phase that follows, is what actually sanitizes the load.
Practical steps to get drier dishes without the extra heat
A few small adjustments close most of the gap between air dry and heated dry, often without touching your settings at all.
- Use rinse aid every cycle. It reduces water’s surface tension so droplets sheet off the dishes instead of beading and sitting, which is one of the most consistent, low-cost upgrades to drying performance across any setting.
- Load with airflow in mind: leave space between items, tilt bowls and cups downward, and keep plastics on the top rack where air circulates more freely.
- Run the hot tap for a few seconds before starting the cycle so the machine is not spending extra energy heating cold water from scratch.
- Choose a cycle with a boosted rinse temperature when your machine offers one, since that extra heat carries into the drying phase even on an air-dry setting.
- Crack the door open a few inches once the cycle ends, or rely on an auto-open feature if your model has one, and unload the lower rack first so water from the top rack does not drip onto clean dishes below.
Pro Tip: Save heated dry for loads heavy on plastic containers or nights you need the dishes back in the cabinet within the hour; skip it for everyday glass and ceramic loads.
Our guide to dishwasher cycles breaks down how boosted rinse options interact with drying if you want to match cycle choice to load type more precisely.
Quick troubleshooting checklist before you blame the setting
Poor drying often has nothing to do with heated versus air dry and everything to do with maintenance. Before changing settings permanently, work through a short checklist:
- Confirm the rinse aid dispenser is full and set to an appropriate dose for your water hardness
- Pull and rinse the filter, and check that spray arms are not clogged with food debris
- Run one load on heated dry and one on air dry with a similar mix of dishes to compare real results in your own kitchen
- Look for blocked vents, a warped rack blocking airflow, or a door latch that is not sealing fully, any of which can leave dishes wetter than they should be
If dishes are still coming out wet after those checks, our deeper troubleshooting guide walks through the less obvious causes, and our follow-up diagnostic article covers what to do when quick fixes do not solve it.
Our take on heated dry versus air dry
For everyday loads of glass, ceramic, and stainless flatware, air dry with rinse aid is the setting we default to: it is quieter, cheaper to run, and good enough most nights. Heated dry earns its spot for plastic-heavy loads or when you genuinely need everything dry within the hour, not as a default you leave switched on out of habit. Every machine behaves a little differently, so a quick side-by-side test and a look at your own manual beats following a blanket rule.

Curated picks to make drying easier
If your current machine struggles no matter which setting you pick, sometimes the fix is less about habits and more about hardware. We keep a curated dishwashers collection that highlights models with auto-open doors, zeolite drying, and other features built specifically to handle the plastic-drying problem better than a basic heating element does.
Beyond the machine itself, small accessories make a real difference: a good rinse aid, an open-slot drying rack for overflow items, and dishwasher-safe mugs and containers that actually hold up to heat. Our dishwasher-safe dinnerware guide is a useful next stop if you are not sure which pieces in your cabinet can handle a heated cycle. And if an insulated mug keeps coming out damaged, this guide to ceramic mugs from our partners at Qahwat Al’ard covers safer everyday options worth considering.

FAQ
Do dishwashers dry dishes as well as towel drying?
Most dishwashers get dishes mostly dry, but glass and ceramic fare far better than plastic, which tends to retain moisture even after a full cycle. Lab testing from Consumer Reports found plastic consistently the hardest item to dry regardless of setting, so a quick towel pass on plastic containers is still common practice.
How do I turn off air dry on my dishwasher?
Most dishwashers let you switch from air dry to a heated or standard dry option directly on the control panel, often with a labeled “Heated Dry” or “Dry” button or a setting inside a cycle menu. Exact steps vary by brand and model, so checking your owner’s manual is the fastest way to find the right control for your specific machine.
What dishwashers use condensation drying?
Condensation drying relies on the temperature difference between the hot tub interior and the cooler stainless steel walls and door, so it appears in many standard dishwashers without a dedicated heating element for drying. ENERGY STAR’s product finder lists drying method as a searchable spec, which is the most reliable way to confirm whether a specific certified model uses condensation drying, heated drying, or another approach.
What is the most sanitary way to dry dishes?
Sanitizing happens during the wash cycle’s final rinse, not the drying phase. Dishwashers certified under NSF/ANSI 184 reach a 150°F final rinse to meet that sanitize standard, so running a sanitize-labeled cycle matters more for hygiene than choosing heated dry over air dry afterward.
