Bosch prints a noise figure for every dishwasher it sells in the US. Each product page on bosch-home.com has a "Silence Level" row in dBA, and each spec sheet repeats it in a "dBA" row. On October 3, 2026, Bosch's US listings held 45 dishwashers, and their figures ran from 38 to 50 dBA.
This page lists all 45, quietest first, in three groups that should only be compared within themselves: full size 24 inch models, shorter ADA-compliant 24 inch models, and 18 inch models. To see how Bosch's figures sit against other brands, see our quietest dishwashers guide; we do not rank other brands here.
Our picks are listed above, with full specifications for each.
How Bosch rates noise
Bosch uses one label across its whole range: "Silence Level" on the product page and "dBA" on the spec sheet, and the two agreed for every model we checked. Many spec sheets also open with "So quiet at 42 dBA" or a similar line. What Bosch never prints is the cycle, the distance or the test standard behind the number. So a Bosch figure tells you how one Bosch compares with another, and much less about how it compares with a brand that tests differently. Our guide to comparing decibel ratings explains why that matters. Not every maker is this consistent: LG sometimes prints one figure as dBA on the product page and dB on the spec sheet, as our LG dishwasher decibels page notes model by model. Miele, by contrast, spells its unit out as "dB(A) re 1 pW", which is sound power; our Miele dishwasher decibels page explains why those figures cannot be lined up against a plain dBA like Bosch's.
Bosch also makes a brand claim. Its product pages carry the headline "the quietest dishwasher brand in the U.S.", footnoted "Based on an average of sound ratings of 24” Full Size Stainless Steel Tub dishwashers contained in major brands websites. Major brands defined as OpenBrand Top 5 Market Share December 2025." Some older pages, such as the 800 Series SHP78CM2N, cite "TraQline Top 5 Market Share December 2021" instead. That is Bosch's claim about an average across its range, not a ranking of individual models, and we have not checked it. The 500 Series SHP95CM5N spec sheet makes a narrower one: "The quietest dishwasher in its class.", footnoted "*Based on TraQline top 5 brands dishwasher market share with MAP pricing $499-$1,249."
Every full size 24 inch Bosch, quietest first
These are standard height models, 33 7/8 inches tall. Prices are Bosch's own on October 3, 2026, and "out of stock" means Bosch's page marked it so that day. Color versions of one model share the figure.

What changes between series
The pattern is simple: the higher the series, the lower the figure. The Benchmark lists 38 or 39, the 800 Series 42, most of the 500 Series 44, the 300 Series 46 to 50, and the 100 Series 48. The 18 inch models sit two dBA above their 24 inch counterparts in the 800 Series.
Bosch does not publish which parts make the difference. Its pages say "A range of technologies makes Bosch the quietest dishwasher brand in the U.S.*" without naming them, and every model's spec rows read "SilentPowerDrive: Yes", including the 50 dBA ones, so that row does not separate them. What the spec sheets do show is the features that change alongside the figure: the Benchmark and 800 Series get CrystalDry and a Flexible 3rd Rack, the 44 dBA 500 Series gets AutoAir, and the 100 and 300 Series use PureDry. We would not credit any of those with the noise difference, since Bosch does not.
Two models break the pattern. The 500 Series SHP95CM5N lists 38 dBA, six below the other 500 Series models, while keeping PureDry and losing ENERGY STAR certification. And the newest 300 Series pair, SHE3ADF5N and SHS3ADF5N, list 50 dBA, two above the 100 Series, with a tub Bosch describes as "Stainless steel with Polinox base".
The handle rarely matters, except on the Benchmark
Across the 100, 300, 500 and 800 Series, every handle style of a given model lists the same figure: pocket, bar, scoop, recessed or custom panel. The Benchmark is the exception. The pocket handle SHP9PCM5N lists 38 dBA, while the bar handle SHX9PCM5N and custom panel SHV9PCM3N list 39, on both product pages and spec sheets. Bosch does not explain the one dBA gap, so check the figure against the exact model number.
InfoLight and TimeLight
A dishwasher this quiet can be hard to hear, and Bosch builds that into the design. In its words: "Based on our legendary sound reduction technology, our dishwashers are so quiet, we provide an InfoLight® that projects a red light onto the floor (or a white light in the pocket handle on select models) to signal that a cycle is running. It turns off once the dishes are done." On the pocket handle 800 Series, the spec sheet says "the InfoLight® bar shines below the handle so you know the dishwasher is running."
The Benchmark gets TimeLight instead. The bar handle and panel ready spec sheets say "TimeLight® shines time remaining on the floor", and the pocket handle sheet says it "shines the time remaining below the handle", although that model's product page row reads "TimeLight®: No", so confirm it with the retailer. Several cheaper models, including the front control 100 Series and SHE43DM 300 Series, list InfoLight as "Not Applicable" and rely on an "End of program audible" signal.
CrystalDry, AutoAir and PureDry
Drying is where the series differ most visibly. PureDry is Bosch's base system: "an energy efficient, closed drying system that does not pull in outside air". CrystalDry, on the Benchmark and 800 Series, "transforms moisture into heat up to 176˚F to get dishes 60% drier,*", footnoted as an aggregate average compared with Bosch's PureDry models. AutoAir, on the 44 dBA 500 Series, "opens the door automatically at the end of the drying cycle" for "40% drier dishes", compared with PureDry after seven hours. None of these is a noise feature, but they are what you pay for between series alongside the lower figure. Samsung prints a plain dBA too, in the product name as well as the spec table; for every Samsung model's published figure, from 38 to 53 dBA, see our Samsung dishwasher decibels page.
What 38 to 50 dBA means in a kitchen
The decibel scale is logarithmic. Roughly every 10 dBA sounds twice as loud, so by Bosch's own figures a 38 dBA Benchmark would sound about half as loud as a 48 dBA 100 Series, and a 42 dBA 800 Series somewhere between. Our decibel chart puts those numbers next to everyday sounds. Small gaps add up: the four dBA between a 46 dBA 300 Series and a 42 dBA 800 Series is easier to notice in an open plan room than the number suggests.
Stock and price on the day we checked
Many Bosch dishwashers showed out of stock on bosch-home.com on October 3, 2026, including both 38 dBA models, every 500 Series and most stainless 800 Series versions. Bosch still lists them, and retailers may have stock. Bosch's own prices ran from $729 for the 100 Series to $1,999 for the Benchmark. Check the exact model number and the price on the day you buy.
We did not measure any of these dishwashers. Every figure is Bosch's own, quoted as published on its US product pages and spec sheets, and Bosch does not say which cycle or test standard its figures describe.
