As far as dishwashers go, the Bosch SNPM88Z75N is an impressive specimen.

Bosch SHPM88Z75N

The Bosch 800 Series SHPM88Z75N (2019) is everything we've come to expect from Bosch—quiet, efficient, and stylish. With a sound rating of 40 dBA, it's one of the quietest dishwashers that's ever come through our labs. This dishwasher did an amazing job removing some of our more difficult stains, like burnt-on cheese and spinach; however, as is the case with most dishwashers, the spinach that got blasted off of our test dishes was occasionally redeposited onto other dishes.

The major selling point of the SHPM88Z75N is its CrystalDry feature. Using zeolite crystals, this dishwasher completely dries all of your dishes, even the plastic tupperware that always seems to need a couple of passes with a dish towel before you can put it away. If your primary method of storing food is with plastic food storage containers, the SHPM88Z75N will save you a lot of extra time and effort when it comes to getting your dishes clean and dry.

Pros

  • Dries plastics

  • stellar stain removal

  • Quiet operation

Cons

  • Expensive

How We Tested

The Testers

Hi there! We're Reviewed's appliance testing team. Between the three of us (Jon Chan, Kyle Hamilton, and Julia MacDougall), we've spent many years testing major appliances including washers, dryers, refrigerators, dishwashers, vacuum cleaners, and robot vacuum cleaners.

We have plenty of experience testing these products in the lab, but we've also used them like normal people would in the course of their daily lives, which means that we have a great sense for what appliances are bargains at their price points, and which appliances have really useful extra features (as opposed to the kitchen-sink approach to features).

With all this in mind, you can feel confident that when we recommend a product, we're giving it our Reviewed stamp of approval, which means two things: firstly, this appliance performs well, and secondly, this appliance is easy to use. We're always reviewing new products, so stay tuned for our reviews and roundups of the latest products in laundry, refrigerators, dishwashers, and vacuum cleaners.

The Tests

Testing dishwashers is a dirty job, and we're happy to do it. We assess each dishwasher on the three major parts of the dishwasher experience— Performance, Features, and Usability.

Stain Removal —We put the three major cycles on a dishwasher (Quick, Heavy, and Normal) to the test by baking food and beverage stains—milk, spinach, egg, oatmeal, meat, and more—onto 15 to 20 dishes that are then loaded into the dishwasher per the manufacturer's loading directions. At the end of each cycle, we determine how much stain has been removed from each dish. Ideally, each dish is 100 percent clean, but that level of cleaning perfection can be harder to achieve in real life.

RedepositRedeposit is the term for when, during the course of a dishwasher cycle, water jets remove bits of food from one dish, only to accidentally get it stuck on a second dish. Any dishwasher that shows little to no evidence of redeposit is a winner in our book.

Number of Dirty Dishes —After a dishwasher cycle has finished, we count the number of dishes that are not 100 percent clean; if your dishwasher can't clean most of your dishes the first time, it's not doing its job correctly.

Cycle Time —Dishwasher cycles can run the gamut from 30 minutes to four hours. Shorter cycle times are much more convenient, especially when it comes to large dinner parties, where you may need to reuse dishes from dinner when it's time for dessert.

Drying —Whether it's accomplished with rinse aid, a built-in heater, or a built-in fan, customers expect their dishes to be dry as well as clean. We penalize the dishwasher every time a dish comes out wet, whether it's sopping wet or just covered in a few water droplets.

While all of the features in the world can't make a bad dishwasher better, they can really add the finishing touch to a dishwasher that does a killer cleaning job. We look at the various cycles, cycle options, and dishwasher specs and assess both a) how useful the features are, and b) how easy it is to actually use those features.

For example, a third rack that primarily holds cutlery can often be a game-changer when it comes to freeing up valuable real estate in the bottom rack. However, if the third rack is rickety, doesn't slide smoothly, or prevents the dishwasher from actually cleaning the cutlery, we would penalize the dishwasher, rather than reward it just for having a third rack. The whole point of a dishwasher is to save you from having to spend time scrubbing every dirty dish by hand; if a particular feature isn't going to make the process of using a dishwasher better or easier, then we don't want it.

The best dishwashers have short cycles, superior stain removal and drying power, and features that make the experience of using a dishwasher a painless one.


What To Look For When Buying A Dishwasher

If your dishwasher just died, chances are that you're in a hurry to replace it. When looking for a new or replacement dishwasher, consider the following topics carefully before buy.

Stain Removal

No one wants to spend hundreds of dollars on a dishwasher that can't get your dishes clean. Stain removal is the most important facet of our dishwasher testing methodology; we add different food and liquid stains onto a variety of dishes to see how well a dishwasher can clean. If you're out shopping for a dishwasher at a store, be sure to ask the sales associate about the dishwasher's cleaning performance. Additionally, you can look through our dishwasher reviews and our dishwasher roundups to see which dishwashers did the best when it comes to cleaning.

Cycles and Cycle Options

If you're just cooking for one or two people, you may not need a pricey dishwasher with a ton of extra options and features. However, if you have a big family or you often host parties, you might need more customizability in your dishwasher's cycles and cycle options. Extra cycles include China Crystal/Delicate for your more delicate dishes, or Sanitize for sports bottles and baby bottles.

When it comes to cycle options, they mostly relate to the location of the water (i.e. Bottle Jets or Half Load) and the water temperature (i.e. Hi Temp).

If none of these options sound useful to you, then you'd probably be happier with a more basic dishwasher with the three main cycles: Normal, Heavy, and Quick.

Drying

As you may have discovered, dishwashers don't always dry your dishes perfectly. If you have a lot of plastic dishes, like tupperware or sports bottles, then you may be really frustrated by the fact that you always have to towel dry these dishes. You can either check out our list of the dishwashers that do a great job of drying your dishes, or you can look for dishwashers that sport extra drying options. Typically, though, dishwashers that have heated drying options (versus just venting the hot air) are more expensive because heated drying requires additional hardware in the dishwasher itself.

Third Rack/Rack Customizability

The third rack is a relatively new development in dishwashers. This narrow tray resides above the top rack, and may or may not have its own wash arm. Depending on the third rack's depth, you can typically fit either just cutlery (that occupy individual tines, and aren't clumped together like they can be in your cutlery basket) or dishes with taller profiles, like ladles, pacifiers, or small bowls. While cleaning results on the third rack might not be as good as they are in the cutlery basket, some people find the convenience of a third rack very enticing.

Another thing to consider is the customizability of the racks themselves. Do all of the tines fold down, or are they rigid? Can you change the height of the racks? Can the cutlery basket be mounted on the door? All of these options give you flexibility when it comes to fitting large or awkwardly-shaped dishes into your dishwasher. If you're mostly washing plates and glasses, though, you might not need to spend the money on this kind of adjustibility.

Efficiency

If you're environmentally- or money-conscious, the prospect of using less water and energy may be appealing to you. Be sure to check out the Energy Star rating for a dishwasher to give you an idea of what you can expect your utility bills to look like. We also talk about energy efficiency in our dishwasher reviews.

Noise

If you have an open-concept floorplan, you might want to look for a dishwasher that has a lower sound rating. These days, dishwashers can go as low as 37 dBA, which is akin to the noise you hear in a library. One thing to note with the sound rating: the value reported is an average. So while lower dBA values are definitely better, you might still experience the occasional loud swishing noise during a cycle.

Additionally, generally speaking, dishwashers with stainless steel tubs are typically quieter than those with plastic tubs. There are pros and cons to both types of dishwasher tubs, though, so noise might not be the only consideration.

Control Panel

Do you prefer buttons or a touch panel? While touch panels definitely look sleeker, some dishwasher touch panels are so sensitive that you (or your kids) can accidentally start cycles by brushing against it. Conversely, some touch panels are so insensitive that you have to jab at them a few times before they work correctly. If you're trying one out in the store, be sure to try out the touch panel before-hand so that you can get a feel for how hard you'll have to press down to get a cycle going.

Fit and Finish

Dishwashers often come in a variety of finishes, from regular white or black to black stainless steel or panel-ready (the ability to install a dishwasher cover that matches your cabinetry). While you should be able to find a dishwasher that matches your kitchen setup and your other appliances, be ready to pay more money for any finish more sophisticated than black/white/stainless steel.

Price

Don't worry: Whether you're on a budget or have a blank check, you can find a dishwasher that gets your dishes clean. While some high-end dishwashers do a really stellar job of removing food stains, more affordable dishwashers won't let you down. Mostly, the price difference between dishwashers is usually down to more or fewer features and options.

What Does dBA Mean?

The dBA abbreviation refers to "A-weighted decibels," which is the unit that dishwasher manufacturers use to measure how loud a dishwasher is during its operation. You've probably heard of decibels as a measure of loudness before, but the "A-weighting" refers to the fact that certain frequencies are more easily perceived by the human ear than others; for instance, a flute solo sounds louder than a bass solo played at the same volume because the human ear is naturally more attuned to mid- and high-range frequencies than it is to bass-range frequencies. As a result, when manufacturers report how loud a dishwasher actually sounds to someone in the same room of the dishwasher while it's turned on, they report that number in terms of A-weighted decibels (dBA), rather than just decibels (dB).


Other Dishwashers We Tested

Samsung DW80R9950UT

The Samsung DW80R9950UT dishwasher has it all. With a third rack deep enough to hold ladles and whisks (in addition to all of your silverware), adjustable tines that will make fitting even the most awkwardly-shaped dishes a breeze, a futuristic-looking control panel, and a fingerprint-resistant stainless steel finish, this dishwasher has enough features to please even the pickiest of dishwasher users.

Even better, the Samsung DW80R9950UT talks and talk and walks the walk: Its cleaning performance is top-notch. The Normal, Quick, and Heavy cycles were all able to remove more than 97% of our test food stains. The Heavy cycle clocks in at about 2.5 hours, so you won't have to do too much waiting around; some Heavy cycles on other dishwashers take as long as four hours to finish. This dishwasher also has minimal spinach redeposit and near-perfect dish drying. For a user-friendly dishwasher with an outstanding cleaning performance, you can't go wrong with the Samsung DW80R9950UT.

Pros

  • Short cycles

  • Third rack

  • Fingerprint-resistant stainless steel finish

Cons

  • None that we could find

LG LDF5545ST

The LG LDF5545ST may look futuristic, but behind its unique integrated handle is a quiet, efficient, stainless steel dishwasher with a plethora of cycles and features. Amazingly, this LG dishwasher has a cleaning performance that is comparable to that of our highest-rated Bosch dishwashers but only costs half as much. The LDF5545ST has the best Heavy Cycle that's ever come through our labs—it removed 100 percent of the stains on every single dish, and showed no evidence of redeposit. The Heavy Cycle took about two and a half hours to finish, but we can hardly complain when extremely dirty dishes come out spotlessly clean.

With a solid warranty and relatively low price, this dishwasher will give you a lot of bang for your buck.

Pros

  • Great cleaning ability

  • Very affordable

  • Very quiet cleaning

Cons

  • None we could find

KitchenAid KDTM354DSS

From design to performance, this all-new dishwasher is all about fluidity and grace. Perhaps most importantly, it's equipped with KitchenAid’s Clean Water Wash technology, which continually removes food particles from the wash water. That means the KitchenAid KDTM354DSS helps clean dishes to actually stay clean by not spraying food removed from one dish onto another dish. Even with this new feature, it's still one of the more efficient dishwashers we've ever tested, with respect to both water and electricity usage.

With a solid cleaning performance, heating drying, and additional spray jets for really tough stains, the KDTM354DSS is a workhorse that can get the job done right the first time.

Pros

  • Great cleaning ability

  • Lots of extra features

Cons

  • Poorer cleaning in the back of the upper rack

LG LDP6797ST

The LG LDP6797ST dishwasher is all about customization. The racks are adjustable both with respect to their tines and their heights, so you can fit in large or awkwardly shaped dishes with ease. Two spray zones allow you to focus on a particular rack in the dishwasher if you're only doing a partial load of dishes. With the seven cycles and a variety of temperature and drying options, you can select exactly the options you need to get your dishes clean, whether it's just a couple of cereal bowls or a whole host of dishes at the end of a dinner party.

When it comes to cleaning performance, the LG LDP6797ST does a solid job. The Heavy cycle has a better cleaning performance than the Normal and Quick cycles, but it clocks in at around 3 hours, so it may be best if you run it overnight. The Normal and Quick cycles do a pretty good job with most food stains, but they both struggled to remove the most difficult stain in our testing, the spinach stain. For everyday messes or special dish-cleaning needs, be sure to check out the LG LDP6797ST.

Pros

  • Eye-catching modern design

  • Third rack with adjustable height

  • Adjustable tines

Cons

  • Normal and turbo cycles left stains behind

Bosch Benchmark SHE89PW55N

The Bosch SHE89PW55N is one of the models in Bosch's flagship Benchmark series. While the Benchmark dishwashers may cost a lot more than other Bosch dishwashers, they do offer some niceties for more discerning customers. In addition to a 39 dBA rating—one of the quietest dishwasher ratings we've seen—the Benchmark series offers panel-ready designs, LCD touchscreens, telescoping racks, a deep third rack, and bright interior lighting.

When it comes to performance, though, the SHE89PW55N is a real marvel. Not only were the Normal, Quick, and Heavy Cycles all equally effective at removing more than 99 percent of all stains, but the cycles are also extremely efficient; they all use very little water and electricity. While you'll pay more up front for this dishwasher, you'll end up saving yourself from dirty dishes and high utility bills.

Pros

  • Amazing cleaning—one of the best we've tested

  • Clean, modern design

  • Runs at a virtually-inaudible 39 dBA.

Cons

  • Its price-to-performance ratio isn't great

  • Its huge list of configurations can be confusing

Bosch SHPM65Z55N

Based on our reviews of other Bosch dishwashers, it’s not surprising that we also love the Bosch 500 series SHPM65Z55N dishwasher. While it’s still on the pricier end of what you might want to pay for a dishwasher, you’re getting a lot of bang for your bucket. With Its quiet operation (44 dBA), adjustable tines, and third rack, you’ll be able to wash many different sizes and types of dishes without worrying about loud noises disrupting your conversation during a dishwasher cycle.

The dishwasher cycles are a bit on the longer side (the Quick cycle clocks in at about an hour), but the cleaning results are worth it. This dishwasher removed nearly all of the stains from our test dishes during the Heavy cycle, which is a rare feat. Additionally, the Auto Air function, which opens the dishwasher door after a cycle has ended to expedite dish drying, is pretty effective; almost every test dish in the Normal and Quick cycles came out bone dry. If you want a Bosch dishwasher but don’t have the budget for a dishwasher in the Bosch 800 series, the Bosch 500 series SHPM65Z55N is a great option.

Pros

  • Quiet

  • Great cleaning ability

  • Gets dishes dry

Cons

  • None that we could find

Bosch SHSM63W55N

The Bosch 300 Series continues to offer the same sleek look, quiet operation, and incredible cleaning prowess that Bosch is known for. We tested the Bosch SHSM63W55N and the Bosch SHXM63WS5N, both of which which removed nearly 100 percent of the stains on the Heavy cycle, an amazing feat which happens rarely in our test labs.

On top of that, this dishwasher also has a third rack, foldable tines, an adjustable upper rack, solid drying, and an optional water softener. This dishwasher is worth every cent and even offers more color choices than the pricier 500 Series.

Pros

  • Great cleaning performance

  • Drying feature that works

  • Third rack

Cons

  • Drying option extends cycle times

Electrolux EI24ID81SS

The Electrolux EI24ID81SS dishwasher has a staggering number of wash cycles, from the regular cycles (Heavy, Normal, Fast) to a cycle just for stemware. There's even an option where you can customize your preferred dishwasher cycle, and then save it as a "Favorite", so that next time, you can activate that cycle with the touch of a button.

As for performance, the Heavy Cycle was one of the best we've seen in our years of testing dishwashers. The EI24ID81SS took no prisoners and only left a few specks of spinach behind. The only downside is that the cycles, with the exception of the 30-minute long Fast Cycle, run long. The Normal Cycle was 2.5 hours, and the Heavy Cycle clocked in at over three hours. If you love having tons of customization options, have a bit of extra cash on hand, and don't need a quick turnaround on your dirty dishes, the Electrolux EI24ID81SS is a great contender for your next dishwasher.

Pros

  • Great cleaning ability

  • LED interior lighting

  • Sleek exterior

Cons

  • Poor cost-to-performance ratio

KitchenAid KDFE104HPS

The KitchenAid KDFE104HPS dishwasher is a great value. With its solid cleaning performance, stellar dish-drying abilities, and its fingerprint-resistant stainless steel finish, this is one dishwasher where you won’t have to compromise on looks, features, or stain removal in order to stay within your budget.

The adjustable top rack and the wide tine spacing means that you shouldn’t have trouble fitting large or awkwardly-shaped items into your dish load. The only downside to this great dishwasher is its long cycle times. The Quick cycle clocks in at about an hour, the Normal cycle is about 90 minutes long, and the Heavy cycle approaches four hours in duration. If long cycle times don’t bother you, though, nice little extras like wine glass holders and options like Sani-Rinse and Hi Temp Wash make the affordable KitchenAid KDFE104HPS dishwasher feel like a luxury purchase.

Pros

  • Solid cleaning performance

  • Dries dishes

Cons

  • Long cycle times

Vinotemp Brama BR-DWSH01-S

The Brama BR-DWSH01-S is the first dishwasher released by Vinotemp, a company much beloved by wine aficionados for its wine storage and cooling solutions. This dishwasher is packed with high-end features, including a sturdy third rack, adjustable tines on every rack, an additional high-powered wash jet for tough stains, and an air exchange system that helps to combat bacteria growth.

The Brama did a great job of removing most stains, but, like most dishwashers we test, stumbled when it came to our most difficult stain, pureed spinach. Spinach redeposit ended up on many of our test dishes. However, for most dirty dishes, this dishwasher should be up to the task of getting them clean. For a high-end dishwasher that doesn’t have a high-end price tag, look no further than the Vinotemp Brama BR-DWSH01-S dishwasher.

Pros

  • Has a third rack

  • Tines are adjustable

  • Air exchange system helps combat bacteria growth

Cons

  • Struggled removing spinach

Whirlpool WDT750SAHZ

With the Whirlpool WDT750SAHZ dishwasher, you’re getting a lot of bang for your buck. This dishwasher has a killer heavy cycle, a smudge-proof stainless steel finish, and a number of extra cycle options and drying features. While the cycles tend to run a little long, we think you'll be pleased with the cleaning results.

Even better, this dishwasher is very adjustable, and won’t have any trouble fitting large or awkwardly-shaped items. It’s easy to fold down the rack tines or to raise or lower the upper rack. If you really need the extra space on the bottom rack, the cutlery basket can be mounted on the door of the dishwasher. For a dishwasher that can take on dishes of any size or shape, check out the Whirlpool WDT750SAHZ.

Pros

  • Extra cycle options and drying features

  • Very adjustable

Cons

  • Cycles run long

Whirlpool WDT730PAHZ

The Whirlpool WDT730PAHZ is an affordable dishwasher with basic features—a cutlery basket with cut-outs for individual knives, forks and spoons, a height-adjustable top rack, and a few extra wash options. It performs best on the Normal cycle, where it removes nearly 100 percent of the food stains, and each dish comes out bone dry.

The only downside is that the cycle times are a bit long; both the Normal and Heavy cycles clock in at over two hours. The 1-Hour cycle, however, lives up to its name and finishes in about an hour. The 1-Hour cycle is not as good at stain removal as the Normal cycle is, but it is able to successfully tackle less dirty dishes. The Whirlpool WDT730PAHZ is a great budget option for those who primarily rely on the Normal cycle to deal with the weekly dish load.

Pros

  • Great cleaning on Normal cycle

  • A good value for its cost

Cons

  • Normal cycle takes a long time—about three hours

Kenmore Elite 14793

If you want a stainless steel dishwasher that can blast away tough stains with high-powered water jets, the Kenmore Elite 14793 is the dishwasher for you. Based on the stellar cleaning results that came out of our test runs of the Heavy and Normal cycles, those jets make all the difference. Even better, the water blasts from the jets do not use excessive amounts of water, meaning that this dishwasher won’t cost you a lot in monthly utility bills.

The SmartDry feature gets your dishes bone dry, but it does extend the cycle time for the Normal (~3 hours) and Heavy (~4 hours) cycles. With options like Hi Temp Wash, Sani Rinse, and Top Rack Only/Bottom Rack Only, it’s easy to customize a dishwasher cycle to your exact specifications. Buy the Kenmore Elite 14793 dishwasher for its classy looks, and keep it for its solid cleaning performance.

GE GPT225SSLSS

If you need a portable dishwasher that cleans dishes as well as (or better than) a fully-installed dishwasher, look no further than the GE GPT225SSLSS. While this dishwasher is definitely one of the most expensive models on this list, you’re getting a lot of bang for your buck. Not only is the cleaning and drying performance of the GPT225SSLSS on par with some Bosch dishwashers we’ve tested, but this dishwasher is one of the only portable dishwashers on the market with a stainless steel finish and a stainless steel tub, the latter of which reportedly cuts down on the noise you hear during a wash cycle.

This 24-inch full-size dishwasher is convertible; you can either keep the castor wheels on and roll it around, or remove the wheels so that it sits flat on the kitchen floor. Even better: if you have tighter size constraints, the GE GPT145SSLSS is the 18-inch version of the GPT225SSLSS, and it cleans dirty dishes nearly as well as the full-size version does. For those with a flexible budget, limited space in the kitchen, and lots of dirty dishes, the GE GPT225SSLSS won’t let you down.

Pros

  • Great cleaning performance

  • Dries dishes

  • Convertible

Cons

  • Few cycle options
