The Short Answer
For most kitchens on Amazon, the Samsung Bespoke DW80B7070 represents the superior value: the lowest cost per place setting at $53.33, plus StormWash+ and an AutoRelease drying door. The LG FlushFit LDNTH862S instead prioritizes quieter 39dB operation and a genuine 1 hour wash-and-dry, justifying roughly $300 more.

You want a connected dishwasher you load, start from your phone, and forget entirely. On Amazon, the smart premium category narrows to two manufacturers that approach the problem oppositely. LG prioritizes a quiet, accelerated finish: QuadWash Pro jets clean from multiple angles, AutoVent opens the door at completion, and the FlushFit delivers a genuine 1 hour wash-and-dry at 39dB. Samsung prioritizes affordability: StormWash+ contributes a rotating jet, an AutoRelease door encourages plastics to air-dry, and the Bespoke undercuts both LG configurations.
This guide evaluates the three smart dishwashers genuinely purchasable on Amazon against one weighted composite, the SHE Premium Dishwasher Value Score, corroborated against Consumer Reports ratings. Compared to the quieter LG FlushFit LDNTH862S Smart Dishwasher, the Samsung Bespoke DW80B7070US Smart Dishwasher calculates to a substantially lower $53.33 per place setting. Premium built-ins from GE Profile and Bosch's flagship tier remain installer and big-box channels, so this comparison stays honest to whatever ships inside an Amazon box.
Best Overall: Quiet + Fast Drying: LG FlushFit LDNTH862S Smart Dishwasher
LG FlushFit LDNTH862S Smart Dishwasher
(Current price, subject to change)
The LG FlushFit LDNTH862S Smart Dishwasher earns the top composite of 9.3 on the SHE Premium Dishwasher Value Score. That weighted figure translates into a concrete outcome: a rated 39dB makes it the quietest unit here, so the quietness factor maxes out completely. QuadWash Pro produces multi-angle high-pressure jets, while heated Dynamic Heat Dry plus AutoVent, which cracks the door at the end, finishes most items dry. Consumer Reports lists the FlushFit line in its dishwasher ratings, and its 16 place settings plus AutoVent door-crack drying are manufacturer-confirmed specifications.
The differentiator is velocity. A genuine 1 hour Wash & Dry clears a complete sixteen-setting load fast, and the adjustable third rack adds real loading flexibility. At $1,099.13 it works out to $68.70 per place setting, the priciest here, which is the honest tradeoff you accept for the quiet, quick finish.
Compared to the Samsung Bespoke DW80B7070US Smart Dishwasher, the LG substitutes a higher cost per setting for a quieter wash, a faster cycle, and one extra place setting. For households that run the dishwasher nightly in an open kitchen, that configuration favors the FlushFit decisively.
What We Love
- Rated 39dB, the quietest unit here by three decibels
- QuadWash Pro plus a genuine 1 hour Wash & Dry, rare at this tier
- AutoVent cracks the door at the end so dishes finish drying on their own
- 16 place settings and full LG ThinQ Wi-Fi
What Could Be Better
- Priced highest here at $68.70 per place setting
- Heated Dynamic Heat Dry finishes plastics less dry than an active-mineral system
- LG service response can lag per owner reports, though its rate still leads Samsung
The Verdict
If you want the quietest, fastest-drying smart dishwasher on Amazon, the LG FlushFit LDNTH862S Smart Dishwasher fits the brief without compromise. The 9.3 reflects what buyers weigh: a 39dB wash, QuadWash Pro, and a real 1 hour cycle. It costs about $300 more than the Samsung, but for quiet and speed, no need to overthink it.
Best Value: Samsung Bespoke DW80B7070US Smart Dishwasher
Samsung Bespoke DW80B7070US Smart Dishwasher
(Current price, subject to change)
The Samsung Bespoke DW80B7070US Smart Dishwasher earns a composite of 8.8 on the SHE Premium Dishwasher Value Score, finishing second overall as the configuration's value champion. At $799.99 it calculates to a category-low $53.33 per place setting, so the affordability factor maximizes completely. StormWash+ pairs dual spray arms with a dedicated rotating jet, and Consumer Reports lists the Bespoke StormWash family in its dishwasher ratings.
The drying approach is pragmatic rather than headline-grabbing. A Smart Dry heated fan performs the work, and the AutoRelease door opens automatically at completion, encouraging plastics to finish in circulating air rather than remaining sealed in residual humidity. Rated at 42dB, it operates quietly enough for most kitchens, registering approximately three decibels above the quieter LG FlushFit at 39dB.
Compared to the LG FlushFit LDNTH862S Smart Dishwasher, the Samsung substitutes a marginally louder wash for a substantially lower cost per place setting alongside the StormWash+ jet. The single consideration is the application: SmartThings is genuinely capable, though owners occasionally re-pair it following a router change. For value-conscious buyers, the Bespoke remains the most economical configuration available here.
What We Love
- Lowest cost in the set at $53.33 per place setting
- StormWash+ adds a rotating jet for targeted cleaning power
- AutoRelease door pops open to help plastics air-dry without extra heat
- Rated 42dB, quiet enough for an open-plan kitchen
What Could Be Better
- SmartThings occasionally needs re-pairing after a router change per owners
- 15 place settings, one rack fewer than the LG FlushFit
- Higher 2026 service rate than LG in reliability tracking
The Verdict
If you want a flagship smart dishwasher without overpaying, the Samsung Bespoke DW80B7070US Smart Dishwasher represents the sensible configuration, because the 8.8 reflects immediately recognizable value: a category-low $53.33 per place setting alongside StormWash+ cleaning and an AutoRelease door. Conceding three decibels to the quieter FlushFit, you will nonetheless be well-served here.
Best for Steam Sanitizing: LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher
LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher
(Current price, subject to change)
The LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher earns a composite of 7.4 on the SHE Premium Dishwasher Value Score, the feature-loaded LG configuration. Its differentiator is TrueSteam, which delivers an NSF-certified 99.999% bacteria reduction on the dedicated Steam cycle, layered over QuadWash spray arms and heated Dynamic Dry. Consumer Reports lists the LDTS5552S in its dishwasher ratings, and the unit's headline draw is the NSF-certified 99.999% TrueSteam sanitizing cycle.
The configurability is genuinely substantial: an adjustable third rack, fifteen place settings, and complete LG ThinQ Wi-Fi for remote start and cycle download. It registers 46dB, comparatively the highest reading of these three, and employs standard QuadWash rather than the Pro arms, without the accelerated 1 hour cycle.
Compared to the LG FlushFit LDNTH862S Smart Dishwasher, this configuration incorporates steam sanitization, calculating to $84.27 per place setting, the highest figure here. Unless steam sanitizing is specifically a requirement, the quieter, faster FlushFit remains the more sensible LG purchase.
What We Love
- TrueSteam delivers NSF-certified 99.999% bacteria reduction
- QuadWash spray arms plus heated Dynamic Dry clean thoroughly
- Full LG ThinQ Wi-Fi smarts, same platform as the FlushFit
- Adjustable third rack and 15 place settings for flexible loading
What Could Be Better
- Highest cost per setting in the set at $84.27
- Rated 46dB, the highest dB reading of the three units
- Standard QuadWash, not Pro, and no 1 hour wash-and-dry
The Verdict
If you sanitize baby bottles or run an allergy-sensitive household, the LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher addresses precisely what matters. The 7.4 reflects a specialized capability most buyers forgo: TrueSteam's NSF-certified 99.999% bacteria reduction. At $84.27 per place setting it ranks as the most expensive here, so you'll be well-served here only if steam sanitizing is your priority.

- WashDry Tech (28%)The strength of the wash system plus the drying method, the axis buyers care about most. LG QuadWash Pro with TrueSteam, a 1 hour Wash & Dry, and AutoVent scores a 9.6; Samsung StormWash+ with a rotating jet, Smart Dry, and an AutoRelease door scores 8.6; LG standard QuadWash with TrueSteam but no Pro arms and no 1 hour cycle scores 8.4.

Ecosystem Fit: ThinQ, SmartThings, and Voice
All three dishwashers are Wi-Fi connected, so ecosystem compatibility rarely determines this matchup. The two LG units operate LG ThinQ; the Samsung runs SmartThings. Each app handles remote start, cycle monitoring, and notifications, and all three integrate with Alexa and Google Home for voice status checks. LG ThinQ adds Proactive Customer Care diagnostics that flag faults before a service call, while Samsung SmartThings folds the dishwasher into a broader Samsung-appliance dashboard if you already own the brand.
The genuine differentiation lives in the hardware, not the protocol. The LG FlushFit pairs a 39dB wash with QuadWash Pro and a 1 hour cycle, the Samsung Bespoke counters at 42dB with the lowest cost per setting and StormWash+, and the LDTS5552S sits at 46dB. Consumer Reports lists all three in its dishwasher ratings; in practice they use capable multi-jet wash systems, so the decision rarely turns on cleaning performance alone. Both ecosystems are mature as of June 2026, so configure the comparison around your floor plan, not around the smart-home badge. The weighted SHE Premium Dishwasher Value Score consequently ranks wash-and-dry technology and quietness above ecosystem compatibility, because that weighted factor balance produces the recommendation buyers genuinely need.

When NOT to Buy
A premium connected dishwasher is not automatically the right decision. If your kitchen operates compactly or you rarely accumulate a complete load, a more affordable unit from our Best Smart Dishwashers 2026: 5 Tested, Quiet Picks hub washes identical dishes for considerably less. The 39dB rating and the 1 hour cycle become capability headroom you financed and never genuinely use. It is also worth naming what is not on Amazon: GE Profile and Bosch's flagship 800 tier are strong machines, yet they sell through big-box and installer channels, so they sit outside this comparison. Match the spend to your kitchen architecture and your habits, and reserve this premium tier for situations where a simpler machine genuinely satisfies the requirement.
Frequently Asked Questions
LG vs Samsung — which dishwasher should I actually buy?
For most kitchens shopping Amazon, buy the Samsung Bespoke DW80B7070: at $53.33 per place setting it is the cheapest here, StormWash+ cleans well, and the AutoRelease door helps plastics dry. Buy the LG FlushFit LDNTH862S instead if a quiet 39dB wash and a genuine 1 hour wash-and-dry matter more than price. The tradeoff is value versus quiet-and-fast, and your priorities decide it.
Which of these is the quietest dishwasher?
The LG FlushFit LDNTH862S, rated at 39dB, is the quietest of the three and the only sub-40 rating here. The Samsung Bespoke sits at 42dB, three decibels louder, and the LG LDTS5552S at 46dB is the loudest. For an open-plan kitchen where the dishwasher runs while you are nearby, the FlushFit's 39dB rating is the clear pick.
Is Samsung StormWash+ better than LG QuadWash Pro?
They take different routes to the same goal. LG QuadWash Pro uses four multi-directional high-pressure arms and pairs with a true 1 hour Wash & Dry. Samsung StormWash+ adds a dedicated rotating jet for targeted zones and an AutoRelease drying door. Both are capable multi-jet systems; in practice the LG leans on speed and quiet, while the Samsung leans on value and the auto-drying door.
Is the LG LDTS5552S with TrueSteam worth the extra money?
Only for steam-sanitizing households. The LDTS5552S adds TrueSteam, an NSF-certified 99.999% bacteria reduction on the Steam cycle, but it costs $84.27 per setting versus the Samsung Bespoke at $53.33 and the LG FlushFit at $68.70. It is also the loudest here at 46dB. If you sanitize baby bottles or run an allergy household, the steam earns its price; otherwise the FlushFit is the quieter, faster LG buy.
Why aren't GE Profile or Bosch flagship dishwashers in this comparison?
Because they are not reliably buyable on Amazon. GE Profile's UltraFresh built-ins and Bosch's flagship 800 Series sell mainly through big-box retailers and installers, and their Amazon listings are frequently parts-only or out of stock. This guide stays honest to the smart dishwashers you can actually add to an Amazon cart today, which narrows the premium field to LG and Samsung.
Can I start and monitor all three from my phone?
Yes. All three are Wi-Fi connected smart dishwashers. The two LG units use the LG ThinQ app and the Samsung uses SmartThings, and each handles remote start, cycle monitoring, and notifications. All three also integrate with Alexa and Google Home for voice status checks. LG ThinQ adds Proactive Customer Care diagnostics, while SmartThings folds into a wider Samsung-appliance dashboard.
Bottom Line
Get the LG FlushFit LDNTH862S Smart Dishwasher if you want the quietest 39dB wash, QuadWash Pro, AutoVent drying, and a genuine 1 hour cycle for a busy open-plan kitchen.
Get the Samsung Bespoke DW80B7070US Smart Dishwasher if you want a flagship smart wash at the lowest cost per place setting, with StormWash+ and an auto-opening drying door.
Get the LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher if you sanitize baby bottles or run an allergy household and specifically want NSF-certified steam sanitizing.
The right call for most kitchens is the Samsung Bespoke DW80B7070US Smart Dishwasher at $53.33 per place setting — the lowest cost here, with StormWash+ and an AutoRelease drying door. For the quietest, fastest wash, the LG FlushFit LDNTH862S Smart Dishwasher wins at 39dB with a true 1 hour cycle. Skip the premium tier if your kitchen is small or your cabinet gap rules out a full-size 24-inch unit — a compact model does the job for less.
