What is the decibel level of an ASKO dishwasher?
An ASKO dishwasher's decibel level is 39, 40 or 42 dB(A) for the household built-in models and 48 dB(A) for the outdoor one, each printed as "Noise level (max)". No current US model lists a figure below 39.
The number appears in the same words in three places: the listing card, the specifications on each product page, and the opening lines of the downloadable product sheet. Wherever we set two of them side by side, for 11 models with product sheets in hand, they matched.
ASKO's series sell sheets repeat it under the banner "Enjoy the power of silence", with the series figure beside it. ASKO writes the unit as dB(A), the A standing for A-weighting.
What does ASKO's "Noise level (max)" label mean?
ASKO's "Noise level (max)" label presents each figure as a maximum, but ASKO does not say what that maximum is taken over. No cycle, distance or test standard appears on its US pages, product sheets, sell sheets or manuals.
ASKO also leaves open which quantity the number reports, sound power or sound pressure. Miele's US data sheets spell out "dB(A) re 1 pW", the reference used for sound power. ASKO's US documents carry no such reference, and the data field behind every product page is simply named "Noise level (max)", with dB(A) as its unit.
That gap matters. A sound power figure describes everything the machine emits, a sound pressure figure what arrives at one spot in the room, and a value of one cannot be ranked against a value of the other.
So ASKO figures line up well with each other, one label across the range, and poorly with anyone else's. An ASKO 39 beside a 39 from Miele or Bosch is two claims whose relation nobody has stated, not a tie.
How many decibels are the ASKO 60 and 60+ Series?
The ASKO 60 and 60+ Series list 39 dB(A) on all four models, ASKO's lowest figure, and their sell sheets add "37 dB(A) in Night Mode". The 60+ adds an 18th place setting, a fourth rack and UV Cleanse.
Prices in these lists are ASKO's own on October 24, 2026, the sale price first and ASKO's struck through price in brackets. All four are 24 inch XXL machines.
- 39 dB(A), 60 Series: DBI776IXXLSSOF, built-in stainless with a pocket handle, $2,499 ($2,899). DFI776XXLSOF, panel ready, $2,499 ($2,899). Both hold 17 place settings on three racks, with no top tray.
- 39 dB(A), 60+ Series: DBI786IXXLSSOF, built-in stainless with a pocket handle, $2,949 ($3,399). DFI786XXLSOF, panel ready, $2,949 ($3,399). Both hold 18 place settings on four racks.
Both lines share Turbo Combi Drying, described as "fan assisted evacuation of moisture in combination with Auto Door Opening", and automatic detergent dosing. The 60+ sell sheet calls 18 place settings the "world’s largest capacity", a claim we have not checked.
How quiet is the ASKO 50 Series?
The ASKO 50 Series lists 40 dB(A) on all seven models, one above the 60 Series, and its sell sheet gives 38 dB(A) in Night mode. Sale prices ran from $1,799 to $2,199.
- 40 dB(A), built-in stainless, XXL: DBI565IXXLS, pocket handle, $1,799 ($2,349). DBI565TXXLS, T-bar handle, $2,099 ($2,449). DBI565PXXLS, Pro handle, $2,199 ($2,549).
- 40 dB(A), panel ready, XXL: DFI565XXL, $1,999 ($2,349). DFI565XXLSOF, with a water softener, $2,049 ($2,499).
- 40 dB(A), panel ready, XL: DFI565, ADA height, $1,899 ($2,249). DSD565, sliding door, $1,999 ($2,349).
All seven hold 16 place settings and have a top tray. Six dry with Turbo Combi Drying, while the sell sheet notes "(DSD565 has Auto door opening drying)", and its product page lists residual heat. Across the series, handle and softener shift the sale price by up to $400 and the noise figure by nothing.
How loud is the ASKO 40 Series?
The ASKO 40 Series lists 42 dB(A) on all seven models, with "40 dB(A) in Night Mode" on its sell sheet. Sale prices ran from $1,249 to $1,599, and five of the seven are XL models built to ADA height.
- 42 dB(A), built-in stainless, XL: DBI564IS, pocket handle, $1,249 ($1,699). DBI364IS, Classic interface, $1,499 ($1,799). DBI564ISSOF, with a water softener, $1,549 ($1,849). DBI564TS, T-bar handle, $1,599 ($1,899).
- 42 dB(A), built-in stainless, XXL: DBI564IXXLS, $1,599 ($1,899).
- 42 dB(A), panel ready: DFI564, XL, $1,499 ($1,799). DFI564XXL, XXL, $1,599 ($1,899).
The 40 Series keeps Turbo Combi Drying and 16 place settings, but its top tray lacks the telescopic rails of the 50 Series, and Wi-Fi, listed on the 50 Series sell sheet, is absent from the 40 Series one. Two dB(A) separate the two series on paper.
Is the ASKO 30 Series dishwasher quiet?
Yes, by ASKO's own numbers the 30 Series matches the 40 Series: all four models list 42 dB(A), and the sell sheet gives 40 dB(A) in Night mode. At $1,049 on sale, they are ASKO's lowest priced dishwashers.
- 42 dB(A), XXL: DBI563IXXLS (stainless), DBI563IXXLW (white) and DFI563XXL (panel ready), $1,049 each ($1,449).
- 42 dB(A), ADA: DFI563ADA, panel ready, size L, 32 3/8 inches high, $1,049 ($1,449).
The 30 Series saves money elsewhere. It holds 14 place settings, dries with residual heat and an opening door instead of a fan, and the sell sheet counts "5 Steel™" parts against eight on the series above. The DFI563ADA does not appear on that sheet, so ASKO gives no Night figure for it.
How loud are ASKO's outdoor and professional dishwashers?
ASKO's outdoor DOD561TXXLS lists 48 dB(A), the highest figure in the range, and its two professional models list 42 dB(A). Neither group has a published Night mode figure.
The outdoor model is freestanding and 24 1/2 inches wide, and its sell sheet calls it "The only UL approved Outdoor Dishwasher." It holds 16 place settings and cost $4,299 on sale ($4,799). Six dB(A) separate it from the 40 and 30 Series, a gap ASKO does not explain.
The professional DWC6432BIXXLSU (built-in) and DWC6432FIXXLU (panel ready) cost $3,999 on sale ($4,499). They are a different kind of machine, with a 30 A supply, hot and cold water connections, an acid proof steel tub and a 240 minute standard program. Their 42 dB(A) matches the 40 Series, but they are built for heavier duty than a household run.
What does Night mode do on an ASKO dishwasher?
ASKO's Night mode quiets the program and makes it longer; the manual's description reads "Lower noise level during the dishwashing program. The program time is extended." Each sell sheet sets the Night figure two dB(A) below that series' maximum.
- 60 and 60+ Series: "37 dB(A) in Night Mode", against 39.
- 50 Series: 38 dB(A), against 40.
- 40 and 30 Series: 40 dB(A), against 42.
Those Night figures come from the sell sheets. Product pages print only the maximum, apart from the 60 Series feature text, "only 39dB(A) (37dB(A) with Night mode)". ASKO does not say how much longer a Night run takes.
Night is a mode laid over a program rather than a program of its own. The manual says the modes on offer "vary between programs", so check that the program you use most accepts it.
Does XL or XXL change an ASKO's noise level?
No. In the 50 and 40 Series, XL and XXL versions list the same dB(A), because ASKO's size letters describe height and the figure follows the series.
XXL models need an opening of 33 7/8 to 34 1/4 inches, the XL ones 32 5/16 to 32 11/16, and the size L DFI563ADA 32 1/2. The 50 and 40 Series sell sheets say "XL models are ADA height compliant", and they call XXL the "Tallest interior tub in the market", a claim we have not tested.
Letters after the digits work the same way. On the sell sheets, SOF models carry a water softener, and I, T and P models carry pocket, T-bar and Pro handles. None of them moves the figure.
Why is my ASKO dishwasher noisy?
ASKO's own troubleshooting table names one noise, a "Rattling sound when dishwashing". It gives the cause as "The dishes are not correctly placed or the spray arms are not rotating." The fix it suggests is to seat the dishes firmly and spin each spray arm by hand.
The same 60 Series manual covers beeps. Feedback volume and notification volume can each be set from 0 to 3, but "Error messages are always indicated by a loud buzzer."
Installation counts too. ASKO's steps include "Fit the sound insulation (only certain models)" under the toe kick, in one or two pieces depending on toe kick depth, so if insulation pieces came in the box, check that the installer fitted them.
Is an ASKO dishwasher quieter than a Bosch or Miele?
No answer holds up on the labels alone. ASKO lists a maximum of 39 to 42 dB(A) indoors, Bosch a Silence Level of 38 to 50 dBA, and Miele, using sound power, between 39 and 44 dB(A) re 1 pW.
Each brand labels its number its own way, and neither ASKO nor Bosch names a method. ASKO's "max" wording sounds cautious, yet with no test standard there is no telling whether its 39 is stricter or looser than Bosch's 38. Read a gap of one or two dB(A) across these three brands as unsettled.
For a fitted kitchen, the same caution applies to panel ready models from other brands.
