If you are tired of hand-washing the flatware and spatulas that never seem to fit, the real fix is a third rack. That slim top drawer is the single biggest upgrade you can make to a dishwasher, and it is the main reason to look past older two-rack models.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The best 3 rack dishwasher for your kitchen balances quiet operation, cleaning power, and a silverware tray that actually earns its space.
Our Picks at a Glance
How To Choose The Best 3 Rack Dishwasher
A third rack adds a slim top drawer for flatware and long utensils, but its design varies: some are fixed, while others are adjustable or removable for extra clearance below. Some hold just flatware, while others take lids and large serving spoons, so the differences matter more than you might expect.
Noise Level in Decibels
The decibel rating measures wash noise: a 49 dB model is as loud as a quiet conversation, while 42-45 dB is nearly silent. A 49 dB machine lets you run it while guests are over, while a 45 dB model is nearly imperceptible, letting you watch TV without knowing the cycle is running. Look for a number in the 45-49 dB range for an open kitchen.
Capacity and the Third Rack Design
The third rack’s design—fixed, adjustable, or removable—determines whether you can fit tall pots below and how easily you load utensils. A fixed rack is fine for flatware, while an adjustable or removable version raises or lowers to clear tall pots in the rack below. That extra 2 inches of clearance is often the difference between fitting a stockpot or leaving it in the sink.

In-Depth Reviews
1. Sharp SDW6506JS
The budget entry point to a third rack, with a 2-inch adjustable upper rack for tall glasses.
If you are new to the three-rack world, this is the price-friendly way in. It packs the same 49 dB library-quiet operation as the pricier Kenmore, paired with a fixed third rack that gives flatware and cooking utensils their own dedicated slot.
Loading flexibility comes from an upper rack that moves up or down by 2 inches, letting you fit taller items or drop it for a stockpot below. The half-load option saves water when you are not filling the whole machine, and the hybrid tub combines stainless steel walls with a plastic floor for durability.
Capacity is 12 place settings with three washing sprayers and a heated dry option. Reviewers point out the machine is quiet enough that they “can’t hear it while watching TV,” and that it cleans dishes really well — though the internal space runs smaller than expected, with tight tine spacing that fits thin plates best.
Why it earns its spot
- The -ish tier price brings real library-quiet operation and a third rack
- Fingerprint-resistant finish keeps smudges off the front
- Half-load mode saves water for smaller daily loads
Where to be careful
- The interior fits thin plates and small dishes best — chunky bowls can feel cramped
- The top silverware rack is shallow and not great for long utensils
Grab it if: you want third-rack convenience and quiet operation at the lowest entry price.
Pass if: you regularly stack thick stoneware or oversized platters, since the tine spacing runs tight.
2. Sharp SDW6726MS
A near-silent washer whose adjustable third rack keeps heavy pots and flatware in one load.
At 47 dB, this is among the quietest machines in its range, and owners say they forget it is running at all. It is 4% quieter than the 49 dB base Sharp model, a difference you feel when the TV is on across the room.
The adjustable third rack lifts to make room for bigger pans in the rack below, and a Power Wash sprayer targets the heavy soil that normally needs a pre-scrub. Soil sensors read how dirty a load is and adjust the cycle automatically, so you are not wasting water on dishes that are barely dirty.
Capacity sits at 12 place settings with 5 wash cycles and 4 options. Buyers report this is “definitely the best one we have ever had and very quiet,” and that the adjustable top rack makes it easy to fit larger cookware underneath.
What owners love
- The noise level is the standout — owners single it out more than any other trait, saying they forget the cycle is running
- The Power Wash sprayer scrubs pans without soaking them first
- Fingerprint-resistant stainless finish keeps the front looking clean
Where it trips up
- Some owners mention the water and drain hookups were poorly aligned from the start
- A few found the included setup frustrating to connect
Reach for it if: you want the best blend of silence, smart cleaning, and a flexible third rack without jumping to premium prices.
Look elsewhere if: you need maximum capacity for a big family, since this holds 12 place settings rather than 15+.
3. Kenmore 22-14632
A 15-place-setting workhorse with a removable third rack that fits far more than the Sharp.
The Kenmore holds 15 place settings, a 25% jump over the 12-place-setting Sharp models, which means a full dinner party’s worth of plates, bowls, and glassware in one load. The removable top-level third rack is the fan favorite, giving spatulas and lids their own home.
Cleaning power comes from three pressurized spray arms using fresh and filtered water, and the SmartWash sensor adjusts the cycle to how dirty the load is. A built-in fan with a heating element dries even plastics, so you can put the dish towel away after the cycle finishes.
It runs at 49 dBA, quiet enough that owners still call it the quietest unit they have owned, and built-in leak detection drains excess water before it causes damage. Customers note the machine removes burnt food from a skillet without any pre-wash and that the rinse cycle helps, though a few note the door feels less solid than older Kenmore models.
Everyday wins
- Cleanliness is what wins people over, with dishes coming out spotless and burnt-on food gone
- The removable third rack means you can add height for a stockpot below
- No bottom-front steam, which owners say makes it safe to install over wood floors
Honest gripes
- Plates and bowls load in one direction only, so organizing takes practice
- The quality gets mixed feedback, with a few units arriving damaged or with a flimsy door
Pick this if: you cook for a crowd and want to stop hand-washing large baking sheets and chef’s tools.
Think twice if: you want a machine that works perfectly from day one without any quirk to learn.
4. Sharp SDW6767HS Smart Dishwasher
A voice-controlled machine with white LED interior lights and a 45 dBA hum you will not hear.
This is the smart-home pick. It works with Alexa, so you can say “Alexa, turn on the dishwasher” from any Echo device, or ask it to set the cycle, mode, wash zone, and check how much time is left. Zero Touch Setup pairs it automatically when you open the Alexa app.
At 45 dBA it is the quietest Sharp on this list, and the bright white LED interior gives you a clear view of what is inside without opening the door and losing heat. Heated Dry with Fan Assist and a Wash Zone that cleans just half a load on either rack round out the convenience.
Shoppers say the machine was “exactly the dishwasher hoped for” once installed, though a few note the Alexa connection was unreliable and a couple saw drain errors within months. The stainless interior adds a premium feel, and the adjustable third rack handles flatware and larger utensils well.
The smart advantage: voice control plus a 45 dBA hum makes this the easiest to run hands-free.
The trade-off: reliability ratings are mixed, so the smart features are not worth it if you just want a simple wash.
Best for: smart-home owners who want to start a load from bed or the couch without touching a button.
Not for: anyone who wants a simple, no-appliance wiring setup, since you need a power cable and water line.
5. COSMO 24 in. Lumin Coll Built-In Top Control
The biggest tub here, holding 16 place settings along with a top-mounted touch panel.
It edges out the Kenmore on raw space — 16 place settings against 15 — and the tall tub gives you room for large or irregular-shaped dishes. The top-mounted touch controls stay out of reach of little hands and wipe clean easily, while exterior sound insulating pads keep noise as low as 45 dB.
The multiple filter system separates soiled and clean water to save both water and energy, and the machine is ENERGY STAR certified to help lower your utility bill. It uses a 120V / 60Hz connection with a 3-prong plug, so a standard outlet works for most installations.
Buyers report the machine is “very quiet” and does “an outstanding cleaning job,” though a few note the bottom rack does not roll smoothly and needs a lift to slide back in. The unit weighs 105 pounds, so plan for two people during installation.
Top billing
- Noise level is the top praise — owners mention an ultra-quiet wash even on heavy loads
- 16 place settings handle large dinner parties in a single cycle
- Stainless steel tub and finish match most kitchen layouts
Keep in mind
- The bottom rack has a design quirk where the wheels do not always fit the rims cleanly
- A few units had control panel failures after about six months of daily use
Choose it for: the largest possible single-load capacity plus a very low noise floor.
skip it if: you want perfect rack gliding — the bottom rack can require a firm push to seat fully.
6. Kenmore Elite 24″ Built-In Dishwasher
A near-silent 42 dBA Elite that dries plastics and adds 35% more third-rack room.
This is the quietest machine in the lineup at 42 dBA, and the Energy Star certification backs its efficiency. The TurboFlex third rack adds 35% more space for utensils, spatulas, and chef’s tools, and it is removable so you can slide trays aside for tall items below.
The MoreSpace Plus Upper Rack adjusts to three heights even when fully loaded, which is rare at this level. TurboDry pulls moisture out with a built-in fan and a heating element, so even plastics come out dry and spot-free. Interior LED lighting and a green floor light make it easy to track the cycle from across the room.
Customers note dishes come out “clean, dry, & SPOTLESS” and that the Extra Dry feature eliminates hand-drying, though a few note the third rack prongs run short. The fingerprint-resistant stainless finish keeps the front clean, and hidden touch controls give a sleek, continuous look with a reach-thru bar handle.
The premium payoff: a 42 dBA silence plus TurboDry that ends the dish towel habit.
The honest catch: a handful of reviewers point out control panel issues requiring service visits, so the expensive tier carries some risk.
Worth it for: anyone who hates hand-drying plastics and wants the quietest wash possible.
Pass if: you are on a budget — this premium tier costs far more for the same core cleaning job.
Understanding the Specs
Decibels (dB) Explained
The decibel rating measures wash noise: a 49 dB model is as loud as a quiet conversation, while 42-45 dB is nearly silent. A 49 dB model is about as loud as a quiet conversation, while a 42-45 dB machine is nearly silent, letting you run it overnight or during a movie without noticing. Lower is better in open-concept homes.
Place Settings and the Third Rack
Place settings indicate load capacity: 12 suits a couple, while 15-16 handles a dinner party. The third rack adds a slim top drawer for flatware and long utensils, freeing up the lower racks for plates and pots. Some racks are fixed, while adjustable or removable versions add clearance below.
