How many decibels is a tall tub KitchenAid dishwasher?
A tall tub KitchenAid lists 41, 44 or 47 dBA, and the rack design decides which. These are 24 inch built-in models, 33.625 inches high. Prices are KitchenAid's own from October 21, 2026, and each color code lists the same figure as its sibling.

How loud are KitchenAid's flush dishwashers?
KitchenAid's flush dishwashers list 39 dBA for the three rack KDTF924PPS and 44 dBA for the two rack panel ready KDTF324PPA. Both are shorter than the tall tub range and sit level with the cabinet doors, so compare them with each other first.
- 39 dBA: KDTF924PPS, PrintShield stainless, front controls, FreeFlex Fit third level rack, $2,099, out of stock.
- 44 dBA: KDTF324PPA, panel ready, two racks, $1,349 on the listing.
On September 27, 2026, kitchenaid.com still sold a third flush model, the panel ready KDTF924PPA, with "39 dBA" in its name and a $1,999 price. In October it no longer appeared on the dishwasher listing, and its old page address loaded a panel ready handle that KitchenAid says fits both the KDTF324PPA and KDTF924PPA. For other makers' options, see our guide to panel ready dishwashers.
Does a more expensive KitchenAid run quieter?
No. KitchenAid's mid priced Third Level Jet Rack models list 41 dBA, below every 360° Max Jets model from $900 to $1,749 at 44 dBA. Only the cheapest rack design, the $1,049 utensil rack pair, lists a higher figure, 47.
What the extra money buys is capacity and drying. The 44 dBA models add a 16th place setting, the 360° Max Jets third rack and a tub KitchenAid calls the "7.25 cu. ft. MaxTub Largest Dishwasher Tub*", footnoted "*Based on usable volume."
The 600 and 700 numbered models add Advanced ProDry, listed as "Heating Element with Fan Assist and Door Open Dry", and the 700s add an interior light. None of those upgrades moves the noise figure.
A buyer who ranks quiet first and capacity second therefore pays less, not more. The $1,199 KDTS324SPS lists three dBA below the $1,749 KDPS724SBE.
Do controls, handle or color change a KitchenAid's dBA?
No. Each KitchenAid rack design keeps one figure whether the controls sit on top or on the front, and whether it has a towel bar, a pocket handle or a long pocket handle.
The 41 dBA Third Level Jet Rack comes as the towel bar KDTS324, the front control KDFS324 and the long pocket KDPS324, and all three list 41. The 360° Max Jets models follow the same rule at 44.
Color works the same way. Juniper (SJP), Black Ore (SBE), black (SBL), white (SWH) and PrintShield Stainless (SPS) versions share the product name and its dBA, with prices up to $100 apart. When matching a retailer's listing on a tall tub model, the first digit of the model number gives the figure away on KitchenAid's own data: 2 for 47 dBA, 3 for 41, and 4, 6 or 7 for 44.
Where does KitchenAid print its dBA, and what is missing?
KitchenAid prints its dBA in the product name and in a feature line reading "Designed for Quiet Cleaning at" the figure. The spec tables we read list "Sound Package: Yes" but carry no decibel row, and no page names a cycle.
The $900 KDTS464SPS shows why the feature text matters: its product name, "360° Max Jets™ Third Rack Dishwasher with 90-Minute Normal Cycle", leaves the figure out, and only the feature list gives "44 dBA".
KitchenAid's quiet dishwasher guide defines the unit as "A-weighted decibels", which it says "essentially measures how loud something sounds to the human ear". It does not say which wash phase, distance or standard sits behind any model's number.
That makes KitchenAid against KitchenAid a reasonable comparison, since one label covers the range. Setting a KitchenAid figure beside another maker's is rougher, as our explainer on comparing decibel ratings sets out.
Why does KitchenAid's quiet guide mention a 39 dBA utensil rack model?
KitchenAid's quiet guide describes a "Third Level Utensil Rack Dishwasher with 30+ Total Wash Jets" at 39 dBA, yet the current models carrying that name, KDTS224SPS and the KDFS224 family, list 47 dBA on their product pages.
The same article says KitchenAid offers "decibel ratings from 39 to 46 dBA", which no longer covers the 47 dBA pair. The article gives no model numbers for its 39 dBA examples, so we could not tie them to anything on sale.
The practical lesson is to read the figure on the product page for the exact model number in front of you. A family name such as "Third Level Utensil Rack" has covered more than one figure on KitchenAid's own site.
How much quieter is a 41 dBA KitchenAid than a 47 dBA one?
A 41 dBA KitchenAid lists six dBA below a 47 dBA one, and by KitchenAid's own rule that "Every increase of 10 decibels doubles the perceived noise level", the gap is a bit over half of one doubling.
On KitchenAid's prices, that step costs about $30 to $150, from the $1,049 utensil rack models to the $1,079.10 KDPS324SPS or the $1,199 KDTS324SPS. Among all the price gaps on this page, it is the cheapest decibel reduction KitchenAid offers.
The guide also prints a chart pairing 41 to 45 dBA with "Moderate rainfall" and 46 to 50 dBA with "Normal conversation at home". Those are KitchenAid's comparisons, not measurements of these dishwashers, and both figures assume KitchenAid tested each model the same way.
Is a KitchenAid dishwasher quieter than a Bosch?
No, not on the lowest figures. Bosch's quietest models list 38 dBA against KitchenAid's 39, and Bosch's range runs to 50 dBA against KitchenAid's 47. Neither brand names a test cycle, so a one or two dBA gap between them settles little.
The closer match is by price. Around $1,200, a KitchenAid Third Level Jet Rack lists 41 dBA. Bosch's Silence Level figures, at its October 3 prices, put the similarly priced 300 Series at 46 dBA and the 800 Series, from $1,399, at 42.
For a ranking across many brands, our quietest dishwashers guide groups models by figure. We would still treat any cross-brand decibel gap of two or less as a tie.
