How Quiet Should a Dishwasher Be?

Dishwasher-makers aggressively tout the quietness of their dishwashers by dBA ratings. A dBA rating expresses a weighted decibel level that puts in human context to how loud or quiet a sound is to our ears, because humans perceive sound differences less sensitively at volume extremes. With dishwashers in the marketplace ranging from 37-64 dBA, what really matters when it comes to quietness and what’s simply hype?

We speak at about 60 dBA, light rainfall registers at 50 dBA, a quiet suburb at night registers at 40 dBA and a whisper registers at 30 dBA. Check out Bosch’s interactive “Understanding Decibels” feature on its website to better understand common noise levels.

Dishwasher dBA

Dishwashers used to average about 65 dBA. Now, the majority of dishwashers have dBA in the low 50s to the 40s, so somewhere between dinner table chatter and scattered showers. Not only is that a vast improvement over what you likely have in your kitchen, but I bet it will clean way better too.

The most quiet dishwashers compete on just one or two dBA levels – a difference that is unnoticeable or barely so. The Miele Futura Diamond dishwasher comes in at 37 dBA when used in its Extra Quiet Program mode; otherwise, it’s rated at 42 dBA. The Bosch 800 Plus comes in a close second at 38 dBA “in normal operation,” which I think means with clean dishes.

Miele explains that dirty dishes often lead to louder operation in competing brands, because the dishwasher has to work harder than during testing. The lowest difference between testing its competitor’s dBA claims using both clean and dirty dishes was about 3 dBA levels, which is barely noticeable.

In the real world, we call this splitting hairs, so such a slight difference should not be your deciding factor. Alternatively, you will likely notice 10 dBA levels, which is the point at which audible sound doubles.

However, how quiet does your dishwasher really need to be not to interrupt your life? Current trends in home layouts have kitchens much more open to the rest of the house, but what the dBA levels don’t remind you of is that sound dissipates with greater distance.

Are you home-schooling your children at the counter or for some strange reason installing a dishwasher in your nursery? If you’re not carrying on important tasks near your dishwasher, take the ratings with a grain of salt and consider price, racking and performance as also very important.

Best Bosch Dishwasher Features

The appliance that hands down gives our customers the most headaches are their dishwashers. They don’t clean, they’re loud, they don’t always fit my big dishes or enough of them at a time.

Note: if this sounds familiar, it might be time to stop making excuses and start making plans for buying a dishwasher.

Certainly there a lot of cool features that dishwasher-makers are coming out with, but we have to give props to a brand that focuses on being the best in those three areas that cause the greatest heartache. Bosch dishwashers are the quietest in their class and are often recognized for their cleaning power. And the newest generation of Bosch dishwashers tweaked the design to free up even more space for dirty dishes.

Bosch Dishwasher Cleaning Power

It’s a novel concept: a dishwasher that washes your dirty dishes so well that you don’t wash them yourself before loading. It’s a bad habit that many can’t shake.

The enclosed dishwasher room at the Bosch training facility is cozy on purpose to amplify every sound a dishwasher makes.

This room was small, so you could really hear the difference a decibel makes.

On a recent visit, we put every imaginable mess on plates that you’d usually soak or rinse off before handing them over to the dishwasher (peanut butter, jam, egg yolks, syrup, etc.).

But they came out clean every time – by no accident of course. This is how they are designed and tested. But it was especially fun to witness this process.

Bosch Dishwasher dBA

Our best Bosch dishwasher in terms of sales registers at 47 dBA, a sound level between hand washing and typing. (FYI, the quietest Bosch dishwasher is 38 dBA, which is scientifically equivalent to a tree falling in the woods when no one is around.) Translation: they’re super quiet.

They achieve this stunningly silent operation through a combination of insulation, water jet trajectory design and quiet-focused mechanics.

Some Bosch dishwashers are so confusingly silent, engineers added InfoLight to beam a small red orb onto the floor beneath to indicate that it was, in fact, running. TimeLight goes a step further to beam the time remaining. Unnecessary? Probably. Cool? You betcha.

Bosch Dishwasher Rackmatic

We’ve all experienced the anxiety of “will it fit?” And I’m not just talking about your skinny jeans in January.

Bosch’s RackMatic design totally gets that the tallest stemware is a favorite for allowing the largest “just one glass of wine” pour. And the tallest cookware (roasting pans, cookie sheets, frying pans) are the ones we least like to tackle by hand.

The unique V-shape of Bosch’s rack means never having to hand wash. Simply  lower or raise the RackMatic rack to accommodate all the awkwardly shaped wine glasses and pans you want.

What Is the Best Dishwasher?

According to Google, inquiring minds want to know: what’s the best dishwasher?

Well, if you read “leading consumer publications,” you already know.

Bosch Ascenta dishwashers top the Consumer Reports’ dishwasher ratings list.

And the cool thing about Bosch dishwashers is all that performance comes packaged in an award-winning design that also is recognized for its excellence in conserving water and energy.

Bosch likes to think that all its consumers enjoy these awards, because of the daily rewards they represent in dependability and simplicity and all that good stuff.

And did we mention these dishwashers are quiet? Babies love Bosch. Don’t believe us?

Who Makes the Quietest Dishwasher?

Imagine a dishwasher so quiet, you can run it during dinner.

Heck, you could run it during a party.

Yeah, that’s a Bosch dishwasher.

You’ve probably heard of Bosch dishwashers. Though you’ve probably never actually heard a Bosch dishwasher.

(watch this video and you’ll see what I mean)

Dishwasher dBA

Dishwasher noise, and for that matter noise in general, is measured in dBA units (or A-weighted decibels…).

Our best-selling Bosch dishwasher, for instance, is 53 dBA.

A vacuum cleaner from 10 feet away is 70 dBA, and a watch ticking is 30 dBA. A three-decibel increase is the auditory equivalent of running two washers at once, according to Bosch.

Bosch’s quietest dishwasher is 39 dBA.
