The quietest dishwashers are the perfect appliance for anyone who's ever been fed up of hearing the sloshing and groaning of their dishwasher. Thanks to technological innovations, modern appliances are designed to keep the noise down. Clever features such as insulation, choice of materials, and quiet motors help transform your kitchen into a calmer environment. 

Selecting one of the best dishwashers for noise levels may be a priority if you have an open-plan kitchen, allowing you to maximize your space. Plus, a quiet model won’t keep you up at night, making it a superb choice if you tend to run a wash in the early hours. 

Noise levels are measured in decibels, with 40 dB being the equivalent of a library. Decibels are on a logarithmic scale, meaning 50 dB sounds about twice as loud as 40 dB. You may also see dBA, which indicates the measurement has been adjusted to reflect how it sounds to the human ear. The dishwashers in our guide range from 38 dB to 44 dB. Be mindful that the same appliance may sound different depending on the setting. Soft furnishings such as rugs can dampen sounds, for example.

The LG signature LUDP8908SN is our top pick of the quietest dishwashers. At 38 dBA, it’s the acoustic equivalent of a hushed library. 

What the users say

The LG signature LUDP8908SN scores a decent 4.4 out of 5 on Home Depot. Many reviewers praised the seriously quiet operation. Others were impressed by the thorough cleaning. There were gripes about longer running times and reports that the drying function left a little to be desired, though most customers were satisfied. 

That makes it the perfect choice if you work from the kitchen table. It’s gentle on the ears thanks to clever technology, including the Inverter Direct Drive Motor and the triple filtration system. 

The minimalist design will fit seamlessly into your kitchen. But it’s not just about looks - this model is packed with impressive features. You can expect sparkling results with Quadwash, with four multi-motion spray arms reaching every nook and cranny. Plus, there are three racks for added flexibility. 

A big draw is the TrueSteam feature, which reduces the appearance of watermarks by up to 60%, resulting in crystal-clear glassware. There are ten cycles to choose from, including a half-load option, an eco-friendly choice for smaller loads. This model is smartphone-compatible, enabling you to operate it on the go.

All of this is rounded off with a 1-year parts and labor warranty, and the motor is guaranteed for ten years, giving you peace of mind. At around $1899 (at the time of writing), it is more expensive than other models. However, if a quiet dishwasher is a top priority, then it may be worth the investment to you. 

The quietest dishwasher: more great picks

While the LG Signature LUDP8908SN is technically the quietest dishwasher you can buy, the options below only differ by a matter of 1-6 decibels, which may not even be noticeable to you. We're particularly excited by the Magic Chef dishwasher, which is almost half the price of the other models and is still only 44 dBA. 

What to look for when choosing the quietest dishwasher

Why is having the quietest dishwasher possible important?

According to a Quiet Mark survey, 84% of Americans agree that noise matters when choosing an appliance. 

“A quiet dishwasher can be a game-changer for many households. From enjoying after-dinner conversation in the kitchen to homes where the living room or bedrooms are in close proximity to the kitchen, a quiet dishwasher gives households the flexibility to run the dishwasher at any time without noisy interruptions,” explains Richard Tarrant, Senior Vice President of the Dish & Laundry Care Business Unit at the BSH Home Appliances Corporation.

“Sound affects our brain waves, heart rate, breathing, hormone secretion, and all of our physical rhythms. Simply put, negative sound depletes our concentration, productivity, general balance, and in excess or extremes can even be fatal as it directly impacts the cardiovascular system,” says Poppy Szkiler, Quiet Mark CEO & CoFounder.

Plus, reducing noise levels in your home has a whole host of benefits for your health and well-being. Choosing a quiet appliance can help create a productive and serene working environment if you work from home.

“Noisy distractions that zap our productivity mean we spend more time completing certain tasks. This can result in longer work hours, leading to increased stress levels. Related anxiety can keep us awake at night, impacting our sleep health, preventing us from recuperating and feeling well,” says Simon Gosling, Quiet Mark Chief Marketing Officer and Host of The Quiet Mark Podcast.

The impact on sleep is a top consideration if you tend to run the dishwasher overnight. It can help you avoid a night of tossing and turning while you struggle to filter out the dishwasher noise.  

If you have little ones, a quiet model may be a wise choice to avoid waking them up. That means they can nap undisturbed, leaving you free to get on with the rest of your day.

What are the downsides to having a quiet dishwasher?

While choosing a quiet dishwasher can have wide-ranging health and well-being benefits, it’s crucial to factor in the potential trade-offs. 

The big one is the price. You can expect to pay more for the privilege of a quiet model compared to a standard appliance. If you want to keep the noise to a minimum, but you’re on a tight budget, look out for special offers when you can snap up a bargain. 

“The lower the decibel rating (dBA), the more material a manufacturer needs to use to insulate and dampen sound. These materials, in conjunction with other features and technologies, all add cost to produce the end product, which can impact the price,” explains Richard.

The other potential downside is installation. It can sometimes be more complex for a quiet model. This is because these appliances tend to have layers of soundproofing to muffle noise. While it may feel like a faff, it’s a one-off job, so on balance, the extra effort may be worth it in the long run. 

Bear in mind the cycle speed and how it affects noise levels. “Cycle speed can impact the noise output of a dishwasher. In some cases, selecting a faster cycle/option combination requires the dishwasher to work faster to deliver proper cleaning results – the result can be slight increases in noise output,” says Richard.
