How many decibels is a JennAir dishwasher?
A current JennAir dishwasher lists 38 or 39 dBA. The figure sits in a "Decibel Level" spec row, in the product name, or in both, and every color or handle version of one design carries the same number.
- 38 dBA, flush, washing third rack: JDAF5924RM (NOIR, $2,099), JDAF5924RX (panel ready, $2,599) and JDAF5924RL (RISE, $2,699).
- 39 dBA, flush, cutlery third rack: JDAF3924RX (panel ready, $1,999).
- 39 dBA, tall tub, cutlery third rack: JDTS3924SM (NOIR, $1,499), JDTS3924SP (pocket handle, $1,499) and JDTS3924SL (RISE, $1,699).
- 39 dBA, tall tub, older design: JDPSS244LM (NOIR, $1,599).
A ninth model, the RISE TriFecta JDTSS246GL, showed on the listing at $2,199 with "38 dBA" in its name. Its product address opened an owner support page instead, so it is not counted above.
How loud are JennAir's flush dishwashers?
JennAir's flush, fully integrated dishwashers list 38 dBA for the three JDAF5924 models and 39 dBA for the panel ready JDAF3924RX. All four are 32.3125 inches high, ask for a 32.313 inch cutout, and include a water softener.
The extra dBA on the JDAF3924RX comes with a different top rack. The 38 dBA models carry a "High Capacity with Wash" third rack with spray arms; the JDAF3924RX has a slim rack for cutlery and no interior light. JennAir does not say which part changes the figure.
The price gap is $600 between the two panel ready models, $1,999 against $2,599. For flush and panel ready models from other makers, our panel ready dishwasher guide ranks them side by side.
How loud are JennAir's standard tall tub dishwashers?
Every standard tall tub JennAir lists 39 dBA. That covers the JDTS3924 trio, 33.625 inches high, and the older JDPSS244LM, 33.5 inches high, all with stainless tubs and 34.5 inch cutouts.
The JDTS3924 models are ENERGY STAR qualified at 240 kWh a year, and their drying row reads "Heating Element with Fan Assist and Door Open Dry". The JDPSS244LM uses "Fan Dry with Heating Element", and its spec table lists 270 kWh a year with "Energy Star Qualified: No".
At $1,499 for the NOIR or pocket handle JDTS3924, a tall tub JennAir costs $600 less than the cheapest 38 dBA flush model. One dBA is the whole difference on paper.
Is the JDTS3924 rated 38 or 39 dBA?
The JDTS3924 is rated 39 dBA in its product name and in its feature tile title, "39 dBA Tranquility System". The text under that same tile reads "At 38 dBA, JennAir is the quietest luxury dishwasher brand", footnoted with the three JDTS3924 model numbers.
We rank it at 39, because the name and tile title agree and the 38 dBA sentence matches the brand line used on the flush models. The spec table has no Decibel Level row to settle it.
The spec rows add one more source of confusion: "Dishwasher Features: 38-39 dBA". That is the same bucket the listing offers as a filter, so it groups models rather than giving a range for one machine.
Does JennAir say which cycle its dBA comes from?
Yes, for its lowest figure. The JDAF5924 pages footnote the 38 dBA claim "*Based on Normal Cycle, Models: JDAF5924RX, JDAF5924RL, JDAF5924RM", and the overview page carries the same note under "no luxury brand is quieter".
That is more than JennAir's sister brands print. KitchenAid's and Whirlpool's dishwasher pages give a bare dBA with no cycle at all, as our KitchenAid decibel chart and Whirlpool decibel chart record.
JennAir still names no distance or test standard, and its 39 dBA tiles on the JDAF3924RX and JDPSS244LM have no footnote. The JDPSS244LM page does say its Normal Cycle is the one "The energy-usage label is based on".
No. JennAir keeps one figure per design, whatever the finish. The NOIR, RISE and panel ready JDAF5924 models all list 38 dBA, and the NOIR, pocket handle and RISE JDTS3924 models all list 39.
Price does change. The NOIR JDAF5924RM was $2,099, the panel ready JDAF5924RX $2,599 and the RISE JDAF5924RL $2,699, so the RISE handle cost $600 more for the same 38 dBA. Among the tall tub models, RISE added $200.
JennAir describes NOIR as stainless steel with "hidden lace textures, discoverable only by touch", and RISE as "an asymmetrical, diamond-knurled texture". Neither description mentions noise.
Which JennAir dishwashers are discontinued?
Four older JennAir model numbers no longer have product pages: the RISE JDPSS244LL, the panel ready JDPSS245LX, and the JDPSS246LL and JDPSS246LM. Their old addresses now open JennAir owner support pages rather than product pages.
The TriFecta JDTSS246GL sits in between. It still appeared on the listing on November 4, 2026, priced at $2,199, yet its product page address redirected to the same kind of owner support page. We list it under alternatives with that warning.
The NOIR JDPSS244LM is the last of the JDPSS244 line on the listing, now that its RISE sibling's page has gone.
Where do JennAir's pages contradict themselves?
JennAir's figures agree wherever they appear, but several other details do not. The tall tub pages in particular say different things in their feature tiles and spec rows.
- JDTS3924SL: the spec table says 14 place settings; a feature tile reads "13 Place Setting Capacity".
- JDTS3924SP: sold as the "Pocket Handle" design, yet its spec row reads "Handle Type: Towel Bar".
- JDPSS244LM: "Energy Star Qualified: No" in the spec table, under a feature tile headed "ENERGY STAR® Certified".
- JDPSS244LM: "Third Level Rack Type: Toss and Go" against a tile for a "Precise Fit 3rd Rack for Cutlery".
None of these touches the dBA, but they matter when you compare capacity or efficiency. Ask a dealer to confirm the ones that decide your purchase.
Is a JennAir quieter than a KitchenAid or Whirlpool?
By one or two dBA at the low end. JennAir's lowest figure is 38 dBA, KitchenAid's is 39 on the flush KDTF924PPS and Whirlpool's is 41 on the WDTS7024RZ, and only JennAir ties its figure to a named cycle.
The bigger difference is the spread. Every JennAir sits at 38 or 39 dBA, while KitchenAid runs to 47 and Whirlpool to 57, so any JennAir lands near the bottom of what its parent company sells.
A one dBA gap between brands is too small to rank on, since none of the three names a distance or standard. Our quietest dishwasher ranking treats a cross-brand gap that small as no real difference.
