Dishwasher buying guide

Last updated: September 2015

Getting started

In our tests, we slather plates with egg yolks, peanut butter, raspberry jam, and other stubborn goo to see which dishwashers made our clean-plate club.

Tougher new rules have slashed the energy and water dishwashers can use and still get the government's Energy Star seal. Dishwashers that meet the federal EPA's voluntary Energy Star standard are, on average, 5 percent more energy efficient and 15 percent more water efficient than standard models. But our latest tests show that even with lower energy and water consumption, you don't have to live with dirty dishes or endure longer cycles. Better yet, some of the biggest energy misers are also easy on your wallet.  

Here's what else to consider:

Look for convenience

Dishwashers that score well for ease of use usually include adjustable racks and lots of flatware slots. Some mid-priced models have third racks that let you lay down large utensils or short cups. Many also have fold-down tines, which let you fit large or odd-shaped dishes and other dinnerware. Stainless-steel tubs resist stains better than white plastic tubs, though some plastic tubs are speckled gray for less noticeable staining.

Match your cleaning habits

Our picks clean well enough for you to skip pre-rinsing. If you do pre-rinse, be sure to turn off the extra-cost power-scrubbing modes. And if you're especially concerned about noise, opt for a modle with a manual-clean filter rather than a self-cleaning one, which tend to be noisier. More models now have manual-clean filters.

Check the controls

Some models include interactive touch controls, but the usual touchpads are fine if they're clearly marked. Also look for cycle-time and other visible displays if a model has controls that are hidden when the door is closed. Many models with hidden controls display a light or other indicator to tell you the dishwasher is running, a plus for extra-quiet models. Still, with cycle times running often two hours or more, we'd prefer a more detailed indicator of remaining cycle time.

Watch the dimensions

The width and depth of every conventional dishwasher is intended for a cavity measuring 24 by 24 inches. But the height of what you're considering could pose a installation challenge if—since the time you installed the old dishwasher—you replaced your kitchen floor or put in a new countertop that dips lower than flush with the bottom edge. Either or both changes could leave less vertical space and require you to buy a slightly shorter dishwasher. Before settling on a model, measure your space and ask the seller for the full height range, accounting for adjustment of the leveling feet.


Aside from performance in our tests, key dishwasher differences include types, costs, and features. Here are the types of dishwashers to consider.


These are a smart buy if you care more about performance than glitz, and are willing to give up a few convenience features.


Pros: As a group, these roughly $600 models often clean dishes nearly as well as premium-priced models. Some include adjustable racks and self-cleaning filters.


Cons: They tend to be noisier than upscale models. Fewer flexible-loading features also make loading and accommodating tall items tougher.


Pros: These roughly $800-plus models tend to be quieter and have ample flatware slots, folding tines, and other flexible-loading features. Hidden controls and a cycle-time display add style and convenience. Many have a stainless-steel tub, which tends to resist stains better than plastic tubs.


Cons: They're not necessarily better than the best mid-priced models at cleaning dishes.


Pros: These typically include two small, stacked drawers you can use simultaneously or separately. Pull-out drawers also ease loading compared with a typical fold-down door.


Cons: They're typically expensive, and models we've tested haven't performed as well overall as less expensive conventional dishwashers. Relatively small capacities also limit how much you can wash and contribute to lower efficiency as a group.


Generally, the more you spend, the more features you'll get. But some aren't worth the extra money so don't pay for more features than you'll use. Here are the dishwasher features to consider.

Adjustable racks and loading aids

Racks that adjust up and down, adjustable tines, and silverware and stemware holders let you reconfigure the interior and organize the contents. Those devices increase flexibility, especially when you cook for a crowd, and they can help accommodate large and oddly shaped items. Certain models go an extra step with, for example, upper racks you can adjust with one hand.

Soil sensor

This adjusts the cycle's time and water use to the load's soil level, improving efficiency.

Rinse/hold cycle

It lets you rinse dirty dishes before you're ready to start a full cycle. This cycle can reduce odors and prevent soil from setting while you accumulate enough dirty dishes for a full load.

Wash zones

Some newer models designate a certain part of the dishwasher for heavily soiled items intended for washing in a special cycle. Such zones don't necessarily run the whole time—with certain models, it's only for a few minutes. In our labs, they do seem to work as promised.


These keep wash water free of food that could be redeposited on clean dishes. There are two types: self-cleaning and manual. With self-cleaning filters, a grinder pulverizes the debris and flushes it down the drain. That's convenient but can be noisy. Some models instead have a filter without a grinder. It's quieter, but it needs periodic cleaning, a job that takes a few minutes.

Third rack

Pay more for your dishwasher, and you're likely to get a third rack for large utensils and small cups (think demitasse). A few models let you raise or lower portions of the rack to fit slightly taller items.

Special wash cycles

Most dishwashers come with at least three cycles: light, normal, and heavy (pots and pans), with many newer models also including "quick" or "express" cycles that clean lightly soiled loads in as little as 20 minutes. Some offer single-rack, pot-scrubber, soak/scrub, steam clean, china/crystal, or sanitizing cycles as well. The three basic cycles should be enough for most chores—even for baked-on food. A sanitizing option that raises water temperature above the typical 140 degrees F doesn't necessarily deliver better cleaning.

Stainless-steel tub

Typically available only starting at mid-priced models, steel tends to resist staining better than light-colored plastic. Gray-speckled plastic tubs also resist stains and trim the overall cost. Any plastic tub should last longer than most people keep a dishwasher. You'll also see some newer models with hybrid stainless/plastic tubs.

Heated dry

Budget-priced dishwashers typically dry solely by drainage and ambient air over the few-hour period following completion of a cycle. Pay more, and some models will either heat the water further during the rinse (to warm up the stainless tub) or use a heating element to dry the dishes—perhaps coupled with a fan to circulate the warm air. All such options, however, can raise your electric bill.

Hidden touchpad controls

Controls mounted along the top edge of the door are strictly a styling touch. They're hidden when the door is closed. You typically can't see cycle progress at a glance, however. Partially hidden controls are a good compromise. They show that the machine is running and often display remaining cycle time. But some have only an indicator light that tells you the dishwasher is running.
