All seven ratings in one table
Three numbers cover the whole range: 39, 42 and 51 dB(A). The 24 inch models hold the low end.
| Sound rating | Model | Front | Bertazzoni price |
|---|
| 39 dB(A) | DW24T3IPT/26 | Panel ready, tall tub | $1,649 |
| 39 dB(A) | DW24T3IXT/26 | Stainless, tall tub | $1,809 |
| 42 dB(A) | DW24T3IPV | Panel ready, tall tub | $1,149 |
| 42 dB(A) | DW24T3IXV | Stainless, tall tub | $1,259 |
| 42 dB(A) | DW24S3IPV | Panel ready, standard tub | $1,149 |
| 51 dB(A) | DW18S2IPV | Panel ready, 18 inch | $1,099 |
| 51 dB(A) | DW18S2IXV | Stainless, 18 inch | $1,268 with a handle kit |
No current model is missing a figure. The product pages repeat each number as "Sound insulation", again in the page title and once more in the description, and on every model they agreed with the sheet.
What does Stealth mode do to Bertazzoni's ratings?
It trades time for quiet, and the 24 inch ratings assume it is switched on. The sheets put it this way: "Super-quiet performance as low as 39 dB(A) with optional Stealth mode", or 42 on the cheaper models.
How big is the cut? For the DW24T3IPT/26 and DW24T3IXT/26, the manual says Stealth "Reduces sound rating by 3 dBA increasing wash time of selected cycle". The DW24T3IPV, DW24T3IXV and DW24S3IPV manuals give 2 dBA instead. Put the sheet and the manual side by side and the implication is clear enough: a regular wash without Stealth lands above the printed figure, by an amount Bertazzoni never publishes. The cycle tables allow Stealth on every program except Quick and Rinse & Hold, so in practice it can stay on for nearly every load.
Tall tub models rate 39 or 42 dB(A)
Their height runs from 33 7/8 up to 35 7/8 inches; they come panel ready or with a stainless door, and the two finishes on each platform share one figure.
| Rating with Stealth | Models and price | Place settings | Controls and extras |
|---|
| 39 dB(A) | DW24T3IPT/26 panel ready, $1,649; DW24T3IXT/26 stainless, $1,809 | 16 | Touch controls, eight cycles, DirectWash zone, water softener |
| 42 dB(A) | DW24T3IPV panel ready, $1,149; DW24T3IXV stainless, $1,259 | 15 | Push buttons, six cycles, floor projection light |
On the listing the DW24T3IPT/26 wears a "New" flag. Cabinet fronts are sold separately: a Carbonio panel and a Bianco Matt panel, $399 each.
Integrated machines from other brands are compared in our guide to quiet panel ready dishwashers.
For a lower or ADA counter, the DW24S3IPV
This is the standard tub option, 32 1/4 to 34 1/4 inches high, listed as "ADA Compliant" and rated 42 dB(A) with Stealth. In most respects it copies the tall DW24T3IPV: 15 place settings, three racks, six cycles, a floor projection status light and the 2 dBA Stealth cut. Both were $1,149 on November 7, 2026.
You can only get it panel ready. Bertazzoni offers no stainless version on the US site, and no 39 dB(A) model is made at this height, so a low counter costs three decibels against the DW24T3IPT/26.
How quiet is the Bertazzoni 18 inch dishwasher?
51 dB(A), the highest figure Bertazzoni prints, and the stainless DW18S2IXV matches it.
Neither 18 inch sheet uses "as low as", and neither lists a Stealth option. That makes their 51 a plain sheet row, while the 24 inch numbers assume the quiet mode, so the 12 dB(A) gap down to 39 overstates how far apart the machines really are by some unknown margin.
The DW18S2IPV measures 17 5/8 inches wide and holds 8 place settings on two racks, with ActiveDry and five options, for $1,099. Narrow machines from other makers are ranked in our 18 inch dishwasher rankings.
The series changes the handle, not the noise
Professional, Master and Heritage pages all sell the same dishwasher model numbers. A Heritage DW24T3IPV rates 42 dB(A), exactly like a Professional one.
Only the handle kit and the bundled price move. On the DW24T3IPT/26 pages the stainless DW24T3IXT/26 came to $1,868 with the $59 Professional kit, $1,878 with the $69 Master kit and $1,948 with the $139 Heritage kit in gold, while the panel ready base model held at $1,649 on all three. Choose the series for the handle you like; the noise figure follows the model number on the sheet.
Why is the DW24T3IPT/26 quieter than the DW24T3IPV?
Bertazzoni does not explain the 39 against 42. The sheets list several differences, and none is labelled as a noise feature.
On the 39 dB(A) model you get touch controls, a DirectWash zone, interior LEDs and a water softener, and the machine weighs 93.9 lbs net against 90.2 for the DW24T3IPV. Both list a "Dual brushless pump system" and a triple stage metal filter, so the pump is not the obvious answer. The Stealth cut differs as well, 3 dBA on the newer model against 2 on the older. Insulation gets only a general mention on the product page, "perfectly insulated and virtually inaudible", and that phrase is used for the 42 dB(A) models too.
How do you mute a Bertazzoni dishwasher?
On a 24 inch model, hold the Extra Dry button for 3 seconds to open the menu, step to Buzzer Sound Control and choose b:0, which the manual says "means all sounds are off".
Out of the box it is set to b:3, "the highest sound level" in the manual's description, with b:1 and b:2 between. With the beeps gone, the floor projection status light does the signalling: steady red while a program runs, steady green once it has finished. The 18 inch manual has no buzzer setting at all, and the DW18S2IPV sheet lists no floor light.
Setting Bertazzoni against other brands
Only loosely. No test standard is named and no "re 1 pW" reference appears, so a Bertazzoni dB(A) may have been measured differently from a rival's, and the 24 inch figures assume Stealth on top of that.
Another maker's plain dBA usually describes a normal cycle. Set it beside Bertazzoni's quiet option and the comparison tilts. Why equal numbers can mean different things is the subject of our piece on cross-brand decibel ratings.
For rivals, the quietest dishwashers guide groups brands by the kind of figure each prints, and the dishwasher noise table lines models up side by side. Compare Bertazzoni with Bertazzoni first.
Nothing on the US listing is discontinued
All seven models were current on November 7, 2026, and the DW24T3IPT/26 carried a "New" flag.
Older Bertazzoni dishwashers under other model numbers, the DW24XV among them, were absent from the US listing and are left out here. A dealer offering a model not named above should be able to point to a spec sheet for that exact number on us.bertazzoni.com; without one, treat any noise figure with suspicion.
