4 Reasons To Consider a Bosch Dishwasher

These appliances have a lot of conveniences going for them. From the practically silent noise level to the broad range of options and prices, you’re likely to find one that works well for you.

1. It’s Ultra Quiet.
Bosch is the quietest dishwasher brand. These machines won’t disturb you as you go about your day. This is especially important if you have an open concept floor plan.

2. It’s Durable.
You’ll be investing in a reliable dishwasher that will last you for many years to come.

3. Variety of Price Points.
Bosch is the only manufacturer that makes a great variety of dishwashers that are suitable for all budgets. The company even thought about specialty cases.

4 Reasons To Steer Clear of a Bosch Dishwasher

If you’re trying to save money or have special space requirements, you might consider broadening your search. Here’s why.

1. Less Expensive Models Don’t Have Heated Dry.
If you want a traditional heated dry on top of the Bosch condensation drying system, your only option is a top of the line machine with CrystalDry.

2. No Bosch Dishwashers Under $599.
If you’re on a tight budget, you may need to look elsewhere.

3. You Have Hard Water.
If you live in an area with hard water and need a dishwasher with water softener, you should know that Bosch doesn’t have a big selection of water softerner models.

4. You Need to Save Space.
If you need a dishwasher drawer or a portable dishwasher, you need to look at other options on the market. Bosch doesn’t make these.

Bosch Dishwasher Design Styles

Bosch dishwashers come in 5 primary design styles across all series:

  • Pocket Handle: The control panel’s hidden from view on the top of the machine, and there’s a reach-in handle on the front. This is the popular Bosch dishwasher design.
  • Recessed Handle: There’s a visible control panel with a reach-in handle.
  • Towel Bar Handle: The controls are hidden at the top of the door, and there’s a towel-bar style handle on the front.
  • Scoop Handle: This style has hidden controls and a small, elegant reach-in handle.
  • Custom Panel: The controls are hidden, and the door can accept custom cabinet panels to match surrounding kitchen décor (not shown below).

Bosch dishwashers are extremely quiet—so much so that they beam a light onto the floor to tell you that they’re running. (Otherwise, you wouldn’t be able to tell.) Bosch calls this feature the infolight or time light, depending on the series. Infolight is standard on all Bosch dishwashers with hidden controls. Time light is reserved for luxury models, and its beam includes time remaining “light stamp.”


6 Best Bosch Dishwashers for 2021

Bosch is the only dishwasher brand with multiple prominent spots on our coveted best dishwashers ranking in 2021. Here are the 6 models we selected to give you a good starting point in your research.

1) Bosch 100 Series Dishwasher: SHXM4AY55N

Bosch SHXM4AY55N

Why We Like It:

  • Ideal when you are on a tight budget
  • Silent at 48 dB. Please note the quietness rating is better on the 100 series compared to that of the old Ascenta series.
  • Decent drying performance (make sure to use rinse aid and load your machine correctly)


  • This is not a model we recommend to our retail customers. Mostly reserved for big box stores where there is no retail sales help.
  • If cleaning performance is paramount for your family spending and extra $100 will get you a far better clean with Bosch 300 Series dishwasher.
  • Plastic bottom.

The SHXM4AY55N belongs to the entry level Bosch 100 Series product family (formerly known as the Ascenta line). It is, however, the go-to model in this series due to its quietness-to-price ratio. Including Bosch’s seasonal rebates, you can get this relatively quiet product for $749 to $799.

  • Variety of finishes (stainless steel, white, black, units that accept cabinet panels, towel bar handle models, etc.)
  • Quiet at 48 dB sound level
  • Comes with stainless steel interior walls but a plastic bottom
  • Standard five wash cycles
  • Spacious with 14 place settings
  • Standard third rack
  • InfoLight projects to the floor in most models

The DLX version of the 100 Series Bosch dishwashers adds the ever-important extra scrub program for heavy-duty cleaning (such as cooked-on food on pots and pans).

Please note that the popular Bosch Ascenta dishwasher SHX3AR75UC has been discontinued and replaced by the 100 Series SHXM4AY55N. The new Bosch 100 Series dishwasher is quieter than the Ascenta at 48 dB and comes with an extra scrub cycle for pots and pans. We felt the need to remark about this model as many review sites still list it erroneously as a current model.

2) Bosch 300 Series Dishwasher: SHEM63W55N

Bosch SHEM63W55N Dishwasher

Why We Like It:

  • All stainless steel interior
  • Very quiet at 44 dB
  • Still at an affordable price point


  • Lacks the sure-fire drying features of 500 and 800 series Bosch dishwashers.

The SHEM63W55N is the most popular Bosch dishwasher under $899. Its price floats around $849 including the manufacturer rebate.

Bosch 300 series dishwashers make up for most of the shortcomings of the 100 series. These models offer everything found in the budget model above plus these features:

  • Full stainless steel interior
  • Much quieter at 44 dB
  • Speed60 Cycle ensures all dishes are clean and dry in under an hour
  • ExtraDry option is a new addition to the feature list to give a heat boost to the condensating dry cycle and get your dishes drier (At this time 300 series Bosch dishwashers do not have AutoAir Dry or CrystalDry)
  • Third Rack is more flexible to accommodate larger items
  • Overall the interior is more flexible by having the ability to adjust the tines and RackMatic, making it easier to make room for larger plates and pots or taller glasses
  • Larger interior capacity with room for 16 place settings
  • Bosch 300 series comes with a variety of design choices as well as models suited for special applications such as ADA height models for raised floors, water softener, and 18-inch dishwashers for smaller kitchens or bar areas.

If you like the feature set of the Bosch 300 series SHEM63W55N but need a 18-inch model for a small kitchen or a bar, you might consider Bosch dishwasher SPE53U55UC. This model is versatile with ADA-compliant height and stainless steel, white, and black color options.

3) Bosch 500 Series Dishwasher w/AutoAir Dry: SHPM65Z55N

Bosch Dishwasher SHPM65Z55N

Why We Like It:

  • Quietness and unique design style that blends with other appliances
  • Auto Air Dry opens the door and leaves it ajar once the program is done, preventing a musty smell
  • Replaced our former favorites, the amazingly reviewed SHP865WD5N and SHPM65W55N models, due to its drying performance (with only a $50 difference in price).
  • Best price vs performance ratio in Bosch lineup.

The Bosch 500 Series SHPM65Z55N dishwasher is a true hit for Bosch. It features the timeless pocket handle design, which fits any kitchen environment. After seasonal rebates, you will be able to purchase this model series for approximately $949 to $999.

Main Features:

  • Bosch added EasyGlide racks as a premium feature onto the 500 Series. You will appreciate the ease of EasyGlide when pulling the fully loaded upper rack in and out.
  • The DLX version of the 500 series packs a critical feature: the extra scrub program for pots and pans.

With the addition of the door that opens after the cycle is over (called AutoAir Dry), this dishwasher will insure you get the best drying job.

4) Bosch 800 Series Dishwasher w/CrystalDry: SHXM78Z55N

Bosch Dishwasher SHXM78Z55N

Why We Like It:

  • Best overall dishwasher. The Bosch 800 Series dishwasher is what the brand is really known for: superior quality fit and finish and exceptional cleaning & drying.
  • Replaces our all-time favorite models SHXM78W55N and SHPM78W55N due to its exclusive CrystalDry feature.
  • If you’re looking for the best drying job, definitely consider the 800 Series Bosch dishwasher with CrystalDry.

The 800 Series dishwashers are the flagship design for Bosch. The SHX878ZD5N stands out in this series as the most popular choice among our customers.

Main Features:

  • Supremely quiet at 42 dB
  • EasyGlide racks
  • Adjustable FlexSpace tines
  • Controls are touch sensitive and luxurious
  • 6 Cycles are the standard on the 800 Series.
  • CrystalDry is an amazing feature that literally gets bone-dry dishes similar to the performance we see in dishwashers with a heating element. A major benefit of CrystalDry is that won’t melt your plastics.

More on Bosch 800 Series Dishwashers:

Some notable Bosch dishwashers in the 800 series lineup feature the MyWay Rack. This special third rack application is ideal for ramekins, cereal bowls, measuring cups, ladles, and more. You can even find a removable flatware tray with tines that fold in this innovative third rack.

In addition, you can find amazingly quiet dishwashers in the 800 series at 39 dB.


The HomeConnect feature gets you Wi-Fi connectivity. HomeConnect allows you the convenience of programming your dishwashing cycles from your phone.

Similar to the 300 Series, Bosch 800 Series dishwashers come with a variety of design choices, as well as models suited for special applications such as ADA height for raised floors. This series also includes models with panel-ready fronts, which will allow you to customize them using your kitchen cabinet finish on the dishwasher. There are also models with a water softener and 18-inch slim dishwashers for smaller kitchens.

Please note that many review sites still talk about an old popular Bosch 800 series dishwasher SHXM98W75N, which has been discontinued and replaced by SHXM88Z75N. This new model now has CrystalDry as an upgrade and a MyWay rack, and is still ultra-quiet at 40 dB.

5) Bosch Benchmark Series Dishwasher w/Panel Ready Door: SHV89PW73N

Bosch Benchmark Dishwasher SHV89PW73N

Why We Like It:

  • Feature rich
  • The quietest dishwasher at 40 dB
  • Panel-ready design lets you customize its look
  • Wi-Fi-enabled HomeConnect app is great for those who want the latest technology.
  • Water softener gives you spotless results and extends the life of your dishwasher. This is great for New Jersey, where we have hard water.
  • MyWay rack can fit more than silverware.
  • Dimming interior lights add a touch of elegance, and look especially impressive at night.

The Bosch Benchmark series is ideal for people seeking the quietest dishwasher with the absolute best cleaning performance. For example, the Bosch Benchmark SHE89PW75N and SHX89PW75N are the quietest Bosch dishwashers on the market at 38 dB rating.

The Bosch Benchmark series also offers the best cleaning performance. We also like their conveniences, such as the interior lights and easy gliding racks.

The SHV89PW73N stands out as a shallow depth dishwasher with a panel-ready finish that lets you integrate it into your cabinets.

6) Bosch 800 Series ADA Dishwasher SGX78B55UC

Bosch SGX78B55UC

Quietness: 44 dB | Interior: Stainless Steel | 3rd Rack: Yes | Place Settings: 15

The most important and unique advantage of the Bosch SGX78B55UC is its water softener feature, which is a must if you live in an area with hard water. It ensures that you’ll never be left with those annoying watermarks on your glasses again. Most important, Bosch makes this critical feature available at a very reasonable price point.

Having said that, most people choose the Bosch SGX68U55UC due to its shorter height, which makes it ideal for kitchens that have raised floors or counters at a non-standard height. Only a handful of manufacturers make ADA dishwashers, and Bosch is by far the most prominent.

This 800 Series dishwasher comes with all the key features found on the rest of the lineup. However, Bosch did not include the AutoAir and CrystalDry options on these special application dishwashers.

However, the SGX78B55UC still comes with an all stainless-steel tub and an ultra-quiet 44 dB noise level. In fact, it’s so quiet that most people don’t even realize it’s on. But not to worry—Bosch’s signature Infolight beams to the floor to indicate operation.

With this model, you’ll also enjoy the convenience of a third rack for silverware as well as added rack flexibilities throughout the machine.

The only complaint we’ve heard from customers about this model is that their dishes aren’t always completely dry at the end of the cycle. However, we expect the CrystalDry option to become available on standard 800 Series machines soon.

Dishwashers in the News

This section is regularly updated by our staff to include the latest industry news surrounding dishwashers.

It’s no secret that everyone loves a quiet dishwasher. To make their dishwasher models so silent, many manufacturers have slowed cycle times to last about two to three hours. In order to conserve energy in the process, the manufacturers also began filtering the dirty water inside the dishwasher instead of wasting ample amounts of fresh water. This is how they’ve achieved both silent operation and energy efficiency.

Because the cycles became so long, many people found shortcuts by washing their dishes by hand, using cycles that bypass the energy-saving “normal” cycle, or running the dishwasher multiple times on the express cycle. However, this change in lifestyle ended up causing just as much water and energy usage.

To remedy this issue, the Department of Energy (DOE) released legislation stating that manufacturers must include a “normal” wash cycle that can wrap up cleaning and drying in under an hour. This cycle will use a sufficient amount of water and energy to give your dishes a full and complete clean.

Bosch has since embraced this legislation. Although Bosch dishwashers already had an express cycle, most users selected the “normal” cycle out of habit. Additionally, the express cycle was less than ideal for cleaning heavily soiled items. Because most people chose to use the normal cycle, Bosch got a bad rep for long wash times. However, this legislation has given Bosch the opportunity to make the normal cycle faster without compromising on performance.

In addition to energy and water efficiency regulations, dishwasher manufacturers can also apply for a sanitation certification from the National Sanitation Foundation (NSF). In order to receive a NSF/ANSI Standard 184 Certification, the sanitizing cycle on residential dishwashers “must achieve a minimum 99.999 percent or 5-log reduction of bacteria” and “reach a final rinse temperature of 150 degrees F.” This certification is increasingly important in today’s world, and is especially important for parents of young children who are often tasked with cleaning bottles and need an extra hot wash. All Bosch dishwashers have PureDry, a setting that features a sanitize option heats the water to 162 degrees F at the end.


Bosch offers different dishwasher styles and a rich feature set to fit any budget. While the 100 and 300 Series dishwashers are ideal for those who are price conscious, the 500 Series and especially the Bosch 800 Series dishwashers will give you a high-quality clean and a number of design choices. Also, Bosch has many options for special applications, such as shorter height ADA units, a water softener for areas with hard water, and 18-inch slim products.


8 Improvements on Bosch Dishwashers:

  1. CrystalDry: Gives you the best drying performance. Reserved for 800 series and Benchmark dishwashers.
  2. AutoAir Dry: Opens the door and leaves it ajar to let moisture escape and enhance drying. Found on 500 series.
  3. MyWay Rack: Bosch transformed the third rack for silverware to accommodate items such as ramekins and large utensils. It calls this feature the MyWay Rack, and it’s found on select models.
  4. EasyGlide Racks: Smooth gliding racks with ball-bearing wheels to make loading and unloading incredibly easy
  5. Adjustable Upper Rack: Available on Bosch 300 series and up
  6. Speed60: This express wash, which finishes in under 60 minutes, is now standard on almost all Bosch dishwashers.
  7. Major sound-insulating improvements
  8. Internet connectivity on models with HomeConnect


Does Bosch make other appliances?

Yes, Bosch manufactures a full set of home appliances. We typically specify Bosch appliances to those customers who target modern features, reliable performance, and a timeless look without spending a fortune.

Bosch refrigerators and washer dryers consistently get great reviews. We also feature their wall ovens as a highly rated appliance. You can see our in-depth write-ups on these products on the links we provided above.

Bosch is part of the BSH group, which owns the Thermador brand known for its residential luxury pro cooking products.

Which Bosch dishwashers dry the best?

Bosch dishwashers with CrystalDry have the best drying performance in the industry. CrystalDry takes the internal temperature to 176 degrees F (a whopping 14 degree increase over the previous ExtraDry feature, and all without additional energy consumption). CrystalDry even outperforms dishwashers with heating elements, and it won’t melt your plastics. Bosch offers CrystalDry in its 800 Series and Benchmark dishwashers.

AutoAir dry is another technology that Bosch employs in its 500 Series dishwasher. We like this feature because it opens the dishwasher door and leaves it ajar after the cycle finishes to let fresh air in. If you usually do your dishes at night, you will be guaranteed a batch of clean, dry dishes in the morning.

Lower tier Bosch dishwashers, including the 100 and 300 series, come with the Extra Dry cycle. This cycle uses slightly higher temperature water in the final rinse to boost condensation drying action.

What is the difference between the Bosch 300 and 500 Series dishwashers?

Bosch 300 series dishwashers are quiet at 44 dB—so much so that Bosch projects a discreet red light beam onto the floor to let you know it’s running. The 300 series is where Bosch starts offering an all-stainless steel interior and a flexible third rack. You’ll find multiple design types in the 300 series to match your style.

The Bosch 500 series has the same quietness rating as the 300 series. However, the interior is upgraded with more flexible tines and a gliding, adjustable middle rack for easy loading and unloading. The most important upgrade on the Bosch 500 series is the recessed handle design. This makes the 500 series a natural replacement for your old dishwasher as it fits in any kitchen.

We must also note that the Bosch 300 series includes the company’s special application dishwashers, such as the slim 18-inch and ADA-compliant units. Bosch’s panel-ready dishwasher selection also starts in this model series.

Does Bosch make Black Stainless Steel color dishwashers?
Yes, Bosch makes black stainless steel dishwashers to match your kitchen design ideas. This modern finish is both fingerprint resistant and durable againsts scratches.

Where are Bosch dishwashers made?
Although Bosch is a German company, it makes almost all of its dishwasher products in North Carolina. Only a few models within the Benchmark Series are made in Germamy.

I have a small kitchen. Does Bosch make 18-inch dishwashers?
Bosch makes 18-inch dishwashers within its 300 and 800 series. These dishwashers are fully featured and extremely quiet at 44 dB. Most models have built-in water softeners and are ADA compliant.

What is a panel-ready dishwasher? Does Bosch make panel-ready dishwashers?
A panel-ready dishwasher allows you to customize the door to match your cabinets. Bosch has a great selection of fully featured panel-ready dishwashers.

How does the Bosch dishwasher model number structure work?
Bosch dishwashers follow a logical model number structure. Here is an example. Let’s break it down for Bosch dishwasher SHXM65Z55N: S– stands for dishwasher. H– means 24-inch width tall tub product. X– denotes handle type, in this case the bar handle. M– exclusive upgraded line or mainline product. 6– decibel rating 44-45db quietness. 5– series in this case 500 series. Z– intro year, in this case 2019. 5-version control. 5– color, in this case stainless steel. N– North America.
