In terms of noise level, 48dBA rating is a solid start when considering 50dbA is the threshold for modern dishwashers.

If the descriptions above featured a long list of words that left you wondering what on earth they mean, don’t worry. In the following guide, we’ll take an in-depth look at what it all means for you as a user. But before we do that, there’s one specialized dishwasher offered by Thermador. The Thermador DWHD771WPR Glass Care Center.

  • Dedicated to Glassware – “Glass Care Center”

Glass Care Center is specially designed to perfectly handle a wide range of glassware, including cocktail and wine glasses and other delicate items. This dishwasher features a tine-less configuration to maximize capacity as well as a no-slip soft rubber rack for wine glasses, beer steins and more. It offers peace of mind for users who wash delicate items, as well as the guarantee that their dishes will be spotless after every cycle.


Capacity is equally impressive, with the ability to hole up to 26 wine glasses of 12 ounces each. The mixed-use top rack also allows you to wash all of your other dishwares while providing an all-new cutlery caddy to clean your utensils for entertaining.


Now let’s take a look at some of the stunning design elements that make the new Thermador Radiance dishwasher line so appealing. Beyond the visually striking options to choose between three handle options – Pro, Masterpiece and a panel ready dishwasher that can be designed to perfectly match your existing appliances), you’ll also enjoy a long list of functional design elements that set the Radiance collection apart from the competition.


Thermador offers a stainless-steel tub in all of their dishwashers, which results in greater durability and convenience. You don’t have to worry about discoloration on your dishwasher’s interior, and you’ll also enjoy improved drying results. Stainless steel interior tubs also result in better noise insulation.

Notable Features of Thermador Dishwashers

Star Dry with Zeolite: Arguably the Thermador dishwasher’s most significant selling point, “Star Dry” is one of the most potent drying functions that you will find anywhere on the market. It provides an efficient process of drying thanks to a powerful mineral called zeolite, which is activated by the steam leaving your dishwasher and it creates a high heat environment to keep your dishes from developing water stains. This is all without the use of chemincals, and no need for replenishment making this a beautifully maintenance-free process. Even if your dishes are plastic, you’ll experience unparalleled drying power. Bone dry dishes are no longer just a fantasy with the power of Star Dry. Available in Sapphire and Star-Sapphire® Dishwashers.

Star Speed: Star Speed Function is also a great addition, as it is both short and very effective while using hot water in a cycle of 20 minutes in length. You will get great results in a shorter time. Only Star-Sapphire models offer this feature.

Water Softener: Water softener is an essential feature if you live in an area with hard water, like northern NJ and other regions. A built-in water softener is perfect if you don’t want to experience water spots on your dishes. All of the models under the Radiance collection (except the Emerald Series) offer this feature.

Powerbeam vs Time Remaining PowerBeam: Thermador dishwashers are very silent and decorative without a control panel facing your kitchen. Therefore, it is hard to know if the dishwasher is actually runnig and how much time is left to go. Thermador, has an elegant usability solution where the dishwasher projects a discreet blue light to the floor to indicate that your machine is operational. On models Topaz and above the PowerBeam incorporates time remaining data as part of the indicator light.

This feature (red vs blue in color of the projected light) is a favorite of Bosch dishwasher users and it is called infolight or timelight in the Bosch world.


Sens-A-Wash®: This feature measures water cleanliness and adjusts the wash cycle, resulting in time and energy saving abilities if your dishes are only lightly soiled. It has introduced a quick wash option that results in additional saved time to help complete cycles in a shorter timeframe.

Sapphire Glow Interior Blue Light: This feature can illuminate when the door is open, allowing you to load your dishes easily. That means better results at the end of each cycle. Only Sapphire Series models include this, but if you are looking for a more advanced lighting option, we offer the Star-Sapphire Series with the Star Glow lighting option, which illuminates your dishwasher with 6 distinct levels of lighting.


Smart Features with HomeConnect: The latest Thermador dishwashers feature Wi-Fi options called HomeConnect that will make your life easier than ever before. Remote monitoring and cycle control and even some troubleshooting options make this a powerful feature for any user.

Push to Open Door: When your hands are full, just nudge the dishwasher door to open it. This is a handy feature if your hands are often full when accessing the dishwasher. You can also design a handleless kitchen with push-to-open technology. You can extend the handleless design to Thermador refrigerators.


Noise level is a crucial but often overlooked feature in quality dishwashers. You don’t want to get distracted in the middle of a TV show or a conversation when your dishwasher starts running a high volume. Home appliance makers understand this, so they’ve been striving for the last few years to make their machines as quiet as possible.

If you want to enjoy a quiet dishwasher, then we recommend that you stay under 48 decibels (dB) of noise rating. This is because anything more than that is going to be noticeable and disruptive in your kitchen and nearby living space. In order to serve as a reference point, the noise level in a library is considered to be around 40 dB, while an average conversation tops out at approximately 55 dB.


Thermador offers very silent dishwashers in a range beginning at 48dbA and reaching as low as 42dbA. Wherever the machine you choose falls within that range, you’re guaranteed not to be distracted by dishwasher noise with a Thermador Radiance machine.

Quietest dishwashers with live audible sound test


With all of these features across the four Radiance series, you’re probably wondering how those features affect the price tag. As you can probably imagine, when you move up the product chain, you will notice that the price rises alongside you. We’ll take a brief look at some of the prices you can expect to spend on base models in each of the four series. If you find Thermador machines for cheaper prices, that’s because they are last year’s models with less up-to-date features.

These series models offer most of the features that you would expect from a modern dishwasher, and Thermador often runs promotions throughout the year to make your purchase worthwhile. In fact, Thermador is currently running a promotion in which any purchase of a Thermador range for your kitchen can give you a free Thermador dishwasher, or $1299 towards the Thermador dishwasher model of your choosing.

Here is a chart showing how each of the four series stacks up in price when it comes to their standard base models:

Model Price
Emerald Series $1399
Topaz Series $1799
Sapphire Series $2299
Star Sapphire Series $2799

Which Thermador Dishwasher Is the Best? Our 3 Top Picks

1) Best Entry Level: Thermador DWHD650WFP, Emerald Series

Thermador DWHD650WFM

Thermador DWHD650WFP Emerald series 24″ dishwasher comes with standard features. It comes with 6 built-in cycles and 5 options, including Sens-A-Wash and the quick wash option. In addition to powerful time-saving features for light soils, the Powerboost feature offers increased water pressure and higher temperature to help combat intense soiling on durable items like pots and pans. As far as noise, this model’s 48 dBA noise rating is good, especially considering 49 dbA is accepted as the threshold for modern dishwashers. It also offers a three-stage filtration system which eliminates sticky residues in recirculating water– that means better results for every wash cycle.

In addition to the features mentioned above, built-in Wi-Fi, a 3-Level adjustable upper rack, and a third rack known as the Chef’s Tool Drawer all come standard to make your dishwashing experience more convenient and enjoyable.

A highly useful 3rd rack of Entertainer Drawers provides plenty of space for the items you’d normally have to wash by hand.
