Yale Appliance Dishwasher Display in Framingham

You are probably researching premium dishwashers, and KitchenAid vs. Thermador dishwashers is a worthwhile comparison on paper. Both are upscale brands.

However, this comparison is not about a better dishwasher.

Your choice depends on two factors - when you are buying your dishwasher and what appliances you are buying with your dishwasher.

At the end of the article, you will know what brand to consider, when to buy it, and how to package your kitchen.

You will also learn about Thermador's new drying technology, and expected reliability of both dishwashers.

This comparison will be interesting.



Thermador Kitchen at Yale Appliance in Boston

Thermador dishwashers are the same as Bosch. Bosch acquired them in the 1990s for their cooking products.

Most companies relabel after acquiring other companies because it's cheaper than building new products. Whirlpool relabeled Kitchen and Maytag products shortly after their acquisitions.

Their new high-end Thermador Sapphire $2,399 and Thermador Star Sapphire $2,799 are unique from Bosch (for now) because they employ zeolite in the drying cycle.

Zeolite is an element from volcanic ash and used in many different applications from supplements to nuclear power plant clean ups (seriously).

I initially searched zeolite months ago for another article, and its many uses are astounding.

In a dishwasher, zeolite increases heat and absorbs moisture. It allows Thermador to advertise a 20-minute wash and dry cycle. I will show a video of dishes washed and dried using zeolite.

Then again, you probably do not want to spend $2,399-$2,799 on a dishwasher. After reading this, you may spend way less.



KitchenAid Full Kitchen Display

Back when I started full time at Yale in 1986, KitchenAid owned the premium dishwasher market. Back then it was manufactured by Hobart, a commercial dishwasher company.

Like many products built back then, it was a workhorse. You could expect 20 years out of your KitchenAid.

Whirlpool bought KitchenAid in the early 1990s. However, around the same time, Bosch entered the market with quieter dishwashers with stainless steel tubs.

Quiet became a new standard. The style of homes changed, with more open living spaces. Living rooms and kitchens merged, so you don't want to hear your dishwasher over your TV or music.

Let's take a look at a few Thermador and KitchenAid dishwashers to compare.

KitchenAid KDTE334GPS Vs. Thermador DWHD650WFM

Most of my comparisons end with products have different strengths and drawbacks. Depending on how you use either, should be the basis of your choice.

Just not in this case.

KitchenAid is the better dishwasher. In fact, this model is KitchenAid's best model, yet not their most expensive.

Here is how they stack up.

Dishwasher Silence Rating

KitchenAid 39 DBs Vs. Bosch at 48 DBs. KitchenAid is silent and one of the quietest dishwashers, whereas, at 48 DBs, you will hear the Thermador.

Pro Tip: Any dishwasher 44 DB and under is considered quiet.

Dishwasher Cycles


KitchenAid's Dishwasher Cycles

Bottle Wash - KitchenAid has separate sprayers on the top rack. It's excellent for sports bottles and baby bottles.


KitchenAid's ProScrub System

ProScrub - Have a cooked lasagna pan left overnight? KitchenAid has concentrated sprays for more cleaning power.

Dishwasher Wi-Fi Compatibility


Thermador Wi-Fi Home Connect

Thermador does have Wi-Fi through Home Connect, so you can see the time remaining or turn on or off your dishwasher remotely.

Dishwasher Panels 

Thermador Custom Panel Dishwasher

The only other Thermador advantage is when you are placing cabinet fronts on your dishwasher.

Thermador and other European style dishwashers do not protrude from your cabinets for a much better look.


KitchenAid's and Thermador's service rate within the first year looks almost identical.

KitchenAid is a better dishwasher and is $200-780 cheaper depending on when you buy it.

Except if you are buying this:


Thermador PRG366GH Professional Range

Thermador Professional Range

With the purchase of qualified Thermador cooking appliances, such as a cooktop and wall oven or a professional range, this dishwasher becomes free after a $1,399 rebate.

Now, what about Thermador's best Sapphire and Star Sapphire dishwashers?

Both Thermador's dishwashers have the best drying methods using zeolite. The Thermador Star Sapphire has a 20-minute wash and dry cycle because it preheats the water an additional 20 minutes.

Moreover, it works well for light to medium soiled dishes (I was surprised). Here is our video test.

Thermador Star Sapphire Dishwasher Test [VIDEO]


KitchenAid is still quieter at 39 vs. 42 or 44 dBAs depending on the model and has the bottle wash and scrub features. Thermador has the best drying in the industry. It even dries plastics well.

The price once again depends on if you are buying Thermador cooking for the rebate. Then again, this comparison can rely on one other variable.

When Should You Buy Appliances?

I wrote this before July 4, 2019 so KitchenAid is now $799, its lowest price during the year. Off promotion, it can be as high as $1,199.

You should plan your appliance buying around significant holidays.

Because many of these holidays stretch on for weeks or even a month, don't worry. 

Black Friday is the best, and it's unofficially Black All November to December 5.

July 4 is the last week of June to July 7. Presidents' Day in February is now Presidents' Three Weeks. Memorial Day and Columbus Day are the other two holidays.

Tax-Free Weekend in Massachusetts is now August 17 and 18th and will have Labor Day promotions.

Which Do You Buy - a KitchenAid or Thermador Dishwasher?

Well, it depends.

KitchenAid is better than the entry Thermador dishwasher unless you are buying a qualifying Thermador cooking appliance. Free is even better in this once lopsided comparison.

If you are placing cabinets on your dishwasher, buy the Thermador (or cheaper Bosch equivalent), because it looks much better.

On the better Thermador dishwashers, you do have the best drying available and the wash on the upgrade.

However, it depends when you buy the KitchenAid and if you are buying a qualifying Thermador cooking appliance.

At $799 during promotion, KitchenAid will be less expensive by $380 with better washing features versus the Thermador with much better drying features.

In the end, it has nothing to do with reliability but other factors like when you will buying the dishwasher, what else will you are buying with this dishwasher and will you be placing on a panel on this dishwasher.
