An auto open door dishwasher releases its door a few inches near the end of the cycle, so steam leaves the tub and room air comes in. Dishes dry with little or no added heat. Consumer Reports says models whose doors pop open automatically at the end of a cycle allow for drier dishes. If you want less leftover moisture, quieter operation and no heating element running at the end, this is the feature to look for. This guide covers how it works, when the door opens, how to switch it on or off, what to do if the door closes again, and how to shop for one.
TL;DR
- Auto open drying cracks the door at the end of the cycle so humid air escapes and fresh air enters. Consumer Reports counts it among the more effective drying approaches.
- Timing and compatible cycles differ by brand and model. Samsung’s U.S. system opens in the last 5 to 15 minutes. Miele can open while program time remains.
- Use rinse aid, load plastics where they can drain, and do not force the door shut for the first couple of minutes.
- Most brands let you turn the feature off in settings or with a button combination. Your owner’s manual has the exact steps.
- When shopping, check the cycle list, noise rating and ENERGY STAR status, then compare models side by side on our dishwashers page.

What an auto-opening dishwasher door actually does
A normal dishwasher finishes its rinse, then relies on residual heat or a heating element to dry. The tub stays shut, so the hot, wet air has nowhere to go. Some of it condenses on the walls and drips back, and some settles on your dishes as droplets.
An auto-opening door changes that last step. The Signature Kitchen Suite owner’s manual describes its Auto Open Dry option as opening the door slightly at the end of cycles that include drying, letting steam out and fresh air in. Brands use different names for the same idea: AutoAir, AutoRelease Dry, AutoOpen, Auto Door Open, Open Door Dry.
The benefit is practical. Dishes come out drier without a long heated-dry phase, and the tub does not sit closed and humid until you unload it.
How well does it dry?
Consumer Reports’ 2026 dishwasher ratings say heated-dry cycles generally get dishes more completely dry than residual-heat systems, while automatic steam-releasing doors are among the more effective drying approaches. So an auto-open door is a strong option, especially if you want to cut back on heated drying.
Plastic is the exception to watch in every dishwasher. The same Signature Kitchen Suite manual explains that plastic and nonstick items are harder to dry because water beads on them and they hold less heat than glass and metal. It suggests Extra Dry or Auto Open Dry for better results. Consumer Reports’ testers also inspect ceramic, glass and plasticware separately for this reason.
Why rinse aid matters more here
The Signature Kitchen Suite manual notes that its Auto Open Dry option does not use a heating element, which makes rinse aid important: rinse aid helps water sheet off dishes before the dry phase begins. If you are new to it, our guide to using dishwasher rinse aid explains how to fill the dispenser and set the dose. It is the cheapest way to improve drying on any dishwasher, and it pairs especially well with a door that opens on its own.
When does the door open?
There is no single rule. Each manufacturer programs the release differently, and the owner’s manual for your model is the final word. Here is what the U.S. documentation says for three common systems.
| Brand and feature | When the door opens | What else to know |
|---|---|---|
| Samsung AutoRelease Dry | During the last 5 to 15 minutes of the cycle, after the internal temperature falls below 122°F | An internal fan runs to protect the countertop from moisture |
| Signature Kitchen Suite Auto Open Dry | At the end of cycles that include drying | No heating element used for this option |
| Miele AutoOpen | On selected programs, sometimes while time remains on the display | Part of the program, intended to dry dishware faster and more thoroughly |

The Miele point surprises people. If your door opens while the display still shows a few minutes left, that is normal on programs that include AutoOpen. Nothing has gone wrong.
Which cycles use it?
Usually only cycles that include a drying phase. A quick rinse or a cycle with drying switched off may not trigger it. Compatible cycles are model-specific, so check the cycle chart in your manual before assuming every setting will open the door. For a plain-language tour of what each setting does and how it affects energy use, see our dishwasher cycles guide.
Should you leave the door open after a cycle?
With an auto-open model, let the machine do it. Samsung’s guidance says not to close the door manually for two minutes after it opens, and the door cannot be pushed shut during that time. The pause gives the steam time to leave.
On a dishwasher without the feature, cracking the door yourself after the cycle ends is a common way to get a similar effect. If you have just stopped a cycle or the machine is still running, take care. Bosch’s safety guidance says to be careful opening during or after a cycle because hot water or steam may escape, and to wait until water noises stop and steam subsides before opening fully. Keep children and pets back while you do it.
Turning auto open on or off
Most brands ship with the feature on. Samsung says AutoRelease Dry is normally on by default and that turning it off can reduce drying performance. If you have a reason to disable it, such as a small kitchen where a swinging door blocks the path, the steps depend on the model.
- Samsung: Some models use the Sanitize and Delay Start buttons to display A1 (on) or A0 (off). Others use a settings menu or cycle and option buttons. Samsung’s U.S. page lists the variations, and its support guidance says the feature is not available on every model.
- Miele: Go to Settings, then AutoOpen, then Off, according to Miele USA.
- Other brands: Look in the manual under the names above: Auto Door Open, Open Door Dry or Natural Dry.
If you must close a Miele door after it has opened, Miele says to wait, open the door fully so the locking rail retracts, then close it. Forcing it is how latches get damaged.
A simple routine for the best result
- Scrape plates but do not pre-rinse heavily, so the sensors and detergent can work properly.
- Keep the rinse aid dispenser full.
- Load plastics on the top rack, angled so water runs off instead of pooling.
- Choose a cycle that includes drying.
- Leave the door alone when it opens, and wait a few minutes before unloading. Hot dishes are easier to handle once they have cooled.
If plastics still come out damp, towel-drying a few items is normal. The Signature Kitchen Suite manual treats that as a material issue, not a defect.
Energy, noise and what the spec sheet tells you
An open-door finish is gentle on energy because it replaces some of the heated drying with airflow. It also tends to appear on premium, quiet machines. A Miele U.S. specification for the G 7166 SCVi XXL lists AutoOpen drying, SensorDry, active condensation drying, ENERGY STAR Most Efficient qualification and a 43 dB operating-noise rating. The G 7266 SCVi lists AutoOpen and condensation drying with 42 dB and ENERGY STAR qualification.
Those numbers show what to read on any spec sheet: the drying method, the decibel rating and the ENERGY STAR label. Consumer Reports measures water and energy use on the default cycle and uses EPA and DOE ENERGY STAR data alongside its own testing. It also notes that advertised water and energy use can run slightly below observed use, a difference worth only a few dollars per year in its testing. So compare models on the label, and do not agonize over small gaps.
If you are weighing rebates for an efficient model, our ENERGY STAR dishwasher rebate guide covers how to look for them.
Heated dry, air dry or auto open?
All three can work. Heated dry is the most thorough on plastics. Air dry saves energy. Auto open sits between them and needs no heating element. If you mostly run glass and ceramic, you may rarely need heat. Our piece on skipping heated dry most nights walks through when each option makes sense.
What to check before you buy
Before you add an auto-open dishwasher to the cart, run through this list.
- Which cycles open the door? The feature is tied to specific programs on most brands. Pick a model whose drying cycles match what you run most.
- Can you turn it off? Settings differ, but a good manual explains it clearly. This matters if your kitchen layout is tight.
- How much clearance is there? The door swings open a few inches. Check that nothing blocks it, and that a countertop edge will not bind the door.
- What is the noise rating? Open-plan homes benefit from lower decibel numbers. The Miele sheets above show what 42 to 43 dB looks like on paper.
- ENERGY STAR status? It helps with running costs and sometimes with rebates.
- Rack flexibility. Adjustable racks help you tilt plastics so they drain.
- Installation style. Built-in or panel-ready models have extra fit checks. Our guide on panel ready dishwasher checks covers them for remodels.
What it costs
Auto-open drying is often found on higher-end machines. One retail listing for a built-in tall-tub model with a third rack and auto open door, rated 38 dBA, showed a price of $1,099.00. Not every model with good drying costs that much. LG’s U.S. page lists a different drying approach, a 1-Hour Wash & Dry dishwasher, at $849.00 for model LDNPH654S. Manufacturer prices change, so treat these as examples and confirm current prices on the product page.
If the door closes again or never opens
The feature should open the door and keep it open. When it does not, the cause is usually mechanical.
- The door closes again right after opening. The door balance system may be out of adjustment. Bosch’s replacement-part instructions say matched left and right springs and cords must be replaced together when door balance is faulty, including doors that close on their own or fail to stay open. Read your manual for the spring adjustment, or have a qualified technician handle it.
- The door never opens. Appliance repair forums list countertop binding, poor leveling, latch-sensor or wiring problems, and a failed auto-open module as possible causes. Start with the simple ones: confirm the feature is on, the cycle includes drying and the machine is level, and that the door edge is not rubbing the cabinet.
- The door opens too early. On Miele models that is often by design, as described above.
- Dishes still wet. Check rinse aid, load pattern and cycle choice. Our guides on common drying problems and fixes that actually work go step by step. If the display shows a code, see our error code guide.
If the machine is under warranty, contact the manufacturer’s service line before opening panels. Springs and cords are under tension, and electrical faults need a licensed technician.
Perspective
Our view is simple: drying is the part of a dishwasher that people notice last and complain about first. A clean glass with water spots reads as a failure, even when the wash was perfect.
That is why we pay attention to how a machine finishes, not only how it washes. A door that opens by itself at the right moment is an easy-to-use answer to a real kitchen problem. It cuts down on the damp tub, on the heated-dry phase and on the second job of towel-drying.
When we curate dishwashers, we look for machines that balance style and function, with user-friendly controls, quality build and drying that works for everyday loads. If you cook most nights, you want the machine to finish the job without you hovering over it.
Pair the feature with rinse aid, load plastics sensibly and read the manual for your model’s cycles. Do that, and an auto-opening door is one of the most hands-off upgrades you can make in a busy kitchen.

FAQ
Does a dishwasher really open by itself?
Yes, on models with an automatic door-opening feature. The door releases a few inches near or at the end of the cycle so steam can escape and fresh air can enter. Brands call it AutoAir, AutoRelease Dry, AutoOpen or Auto Door Open, and not every model in a brand’s range has it.
How do I stop my Samsung dishwasher from opening automatically?
The method depends on the model. Some Samsung dishwashers use the Sanitize and Delay Start buttons to show A1 for on or A0 for off, while others use a settings menu or option buttons. Samsung notes that turning AutoRelease Dry off can reduce drying performance, so check your manual for the exact steps.
Are you supposed to leave the dishwasher door open?
If your dishwasher has auto open, let it open itself and do not push it shut for about two minutes. Without that feature, cracking the door after the cycle can help moisture escape. Wait until steam subsides before opening fully, since hot steam can escape right after a cycle.
Why does my auto-opening dishwasher door close again?
The usual cause is door balance. Springs and cords that are worn or mismatched can let the door swing shut after it opens. Bosch’s parts instructions say matched left and right springs and cords should be replaced together, so ask a qualified technician or the manufacturer’s service line to check it.
