- Premium Choice: Honeywell 24 Inch Dishwasher with 12 Place settings, 7 Washing Cycles, Stainless Steel and Plastic Tub, UL/Energy Star- Stainless Steel
Last updated: September 9, 2026
A kitchen appliance that quietly runs after dinner should not add a noticeable line to your electric bill. Energy efficient dishwashers are built to solve a very specific problem: they clean the same load of plates and utensils as a standard model while drawing less water and less power per cycle. The gap between a genuinely efficient machine and one that merely carries an Energy Star label comes down to motor design, insulation quality, water recirculation logic, and how well the tub retains heat through the drying phase.
As the editor for this roundup, I compared every unit listed below against published spec sheets, current street prices, and aggregated owner feedback across multiple retail platforms. The eight machines here span portable countertop models for renters and full built-ins for kitchen renovations. What separates the standouts from the rest is not a single headline number but a pattern: consistent low-water-cycle claims backed by real owner reports, durable tub materials that resist mineral buildup, and smart drying methods that do not rely on a high-wattage heating element.

How We Picked
For a category defined by efficiency, four criteria carry disproportionate weight. First, energy certification: Energy Star or an equivalent third-party rating is the baseline because it confirms the unit meets federal water and electricity thresholds. Second, tub material: stainless steel resists staining, odor absorption, and mineral scale far better than plastic, which directly affects long-term efficiency since a scaled tub heats less evenly. Third, place-setting capacity matched to household size: oversized machines waste water on partial loads, while undersized units force multiple cycles that erode savings. Fourth, real owner feedback on drying performance and noise: a machine that leaves dishes damp forces users to run extra cycles or dry by hand, negating the efficiency gain.
The 8 Best Energy Efficient Dishwashers in 2026
1. COMFEE’ Countertop Dishwasher Portable, 6 Place Settings, Energy Star
This is the entry-level choice for someone who wants Energy Star validation without committing to a full kitchen remodel. The six-place-setting capacity suits a one- or two-person household that cooks daily but does not accumulate mountains of cookware. Owners consistently praise how quiet the cycle runs and how little water it consumes compared to hand-washing the same pile. The main trade-off is loading flexibility: tall plates and bulky pots sometimes crowd the rack, forcing two runs instead of one.
- Pro: Lowest price in this roundup with a verified Energy Star badge.
- Pro: Portable design plugs into a standard outlet and connects to the faucet without installation.
- Con: Six settings limit capacity for families or heavy cooking nights.
Skip this if you regularly wash large pots, baking sheets, or more than six full place settings in one sitting.
2. Midea 18 Inch Built-in Dishwasher, 8 Place Settings, Stainless Steel Tub
Midea’s 18-inch built-in occupies a middle ground between compact portables and full 24-inch machines, making it a strong fit for apartment kitchens or secondary bathrooms where a full-width unit would be overkill. The stainless steel tub is the headline feature: owners report better drying results and noticeably lower noise versus plastic-tub competitors. At this price it is the priciest entry in the roundup, but the build quality justifies it for anyone planning to keep the machine for several years.
- Pro: Stainless tub resists odor and scale, preserving efficiency over time.
- Pro: Eight settings fit small families without the footprint of a 24-inch unit.
- Con: Requires permanent plumbing and electrical hookup; not renter-friendly.
Skip this if you are in a rental, a dorm, or any kitchen where you cannot run a dedicated water line and a 120-volt circuit to the install point.
3. Honeywell 24 Inch Dishwasher with 12 Place Settings, 7 Washing Cycles, Stainless Steel and Plastic Tub, UL/Energy Star
For households of four or more, a 24-inch machine eliminates the need for mid-cycle reloading. This Honeywell offers twelve place settings and seven wash cycles, giving users the ability to select a shorter eco-mode when the load is light. The mixed stainless-and-plastic tub construction keeps the price well under comparable full-size models. Owner feedback highlights the adjustable upper rack and the effective heated-dry option as standout conveniences.
- Pro: Largest capacity in this roundup; handles a full day of cooking for a family.
- Pro: Seven cycles let you match water and energy use to the soil level.
- Con: Mixed tub materials mean the plastic sections can absorb odors faster than an all-stainless interior.
Skip this if your kitchen cabinet opening is narrower than 24 inches or if you rarely generate enough dirty dishes to fill a full-size load.
4. COMFEE’ Countertop Dishwasher, Energy Star Portable, 6 Place Settings, 8 Washing Programs, Black
The upgraded COMFEE’ countertop adds two extra wash programs over its budget sibling, including dedicated baby-care and glass cycles that matter for households with infants or fine stemware. The black finish is a cosmetic difference but appeals to modern kitchen aesthetics. Owners appreciate the speed cycle for lightly soiled daily dishes and note that the ECO program keeps water consumption minimal. The core limitation remains the same six-place-setting cap.
- Pro: Eight programs include specialized cycles for delicate glassware and baby items.
- Pro: Same portable faucet-connection design; no installation required.
- Con: Still limited to six place settings, so large loads require splitting.
Skip this if you do not need the extra programs; the cheaper COMFEE’ model covers the same basics at a lower cost.
5. Midea 18 Inch Built-in Dishwasher, 8 Place Settings, Stainless Steel Tub
Functionally near-identical to the first Midea 18-inch listing, this variant arrives at a lower price point, making it the value pick among built-in options in this group. Owners describe the same quiet stainless-tub operation and comparable cycle options. The price difference likely reflects a different color, finish, or minor trim variation rather than a change in core hardware, which is why it earns a spot as the budget-conscious built-in recommendation.
- Pro: Stainless tub performance at a more accessible price than the flagship Midea listing.
- Pro: Compact 18-inch width fits narrow cabinet spaces common in older apartments.
- Con: Installation requirements are the same as any built-in: plumbing, power, and a permanent opening.
Skip this if you can stretch the budget to a 24-inch machine and need more than eight settings per load.
6. Midea 18 Inch Built-in Dishwasher, 8 Place Settings, Stainless Steel Tub
This third Midea 18-inch entry sits between the other two on price and appears to be a trim or finish variant. The stainless tub, eight-place-setting layout, and built-in form factor remain constant. Owner sentiment mirrors the siblings: quiet operation, reliable cleaning on normal cycles, and a drying performance that benefits from the heat-retaining metal interior. Buyers comparing all three should treat them as near-equivalent and select based on the lowest available price and preferred exterior color.
- Pro: Consistent stainless-tub drying and noise performance across the Midea 18-inch line.
- Pro: Slightly under the flagship price while matching its core hardware.
- Con: Minimal differentiation from the other Midea listings can make the choice confusing.
Skip this if the cheaper Midea variant is in stock; there is no spec reason to pay more here.
7. NOVETE Portable Countertop Dishwasher for Small Apartments
NOVETE’s unit targets the same renter and small-apartment audience as the COMFEE’ models but differentiates through a design language that emphasizes simple controls and a compact footprint. Owners note the water-tank option in addition to the faucet connection, which is useful in kitchens where reaching a faucet adapter is awkward. Cleaning performance on everyday plates is rated well, though heavy grease on baking sheets still benefits from a pre-rinse.
- Pro: Dual water-supply flexibility (tank or faucet) removes a common install headache.
- Pro: Compact footprint suits narrow countertops without sacrificing a portable design.
- Con: No Energy Star certification listed, so efficiency claims rest on manufacturer data alone.
Skip this if a certified Energy Star badge is a hard requirement for your utility rebate or personal criteria.
8. Honeywell 18 Inch Dishwasher with 8 Place Settings, 6 Washing Programs, Stainless Steel Tub, UL/Energy Star, White
Honeywell’s 18-inch built-in rounds out the compact-install options with a white finish and full Energy Star plus UL certification. Six wash programs cover the typical spread from heavy pots to gentle glass. The stainless steel tub matches the Midea units on durability and drying, and owners frequently mention the quiet motor and the adjustable rack that accommodates taller items. At this price it competes directly with the value Midea, so color preference and brand trust tip the decision.
- Pro: Energy Star and UL listed, qualifying for most efficiency rebate programs.
- Pro: White finish blends into traditional kitchen cabinetry better than stainless fronts.
- Con: Eight settings still require splitting very large loads across two cycles.
Skip this if you need more than eight place settings per cycle or prefer a stainless-look front panel.
Buying Guide
Energy Star Certification and Cycle Water Use
Energy Star sets a ceiling on kilowatt-hours and gallons per full cycle. When comparing units, look for the estimated annual energy use in the spec sheet rather than relying on the label alone. A machine that uses noticeably fewer gallons per cycle will still feel efficient only if the drying phase does not compensate with a high-wattage heating element. Condensation drying, common in stainless-tub models, leverages residual heat and a fan rather than a bare electric coil, keeping power draw lower at the end of every cycle.
Tub Material and Long-Term Efficiency
Stainless steel tubs cost more upfront but resist the mineral buildup and odor absorption that degrade a plastic tub’s performance over time. Scale on heating surfaces and spray arms forces the machine to work harder to achieve the same clean, gradually pushing energy and water consumption above rated figures. If you live in a hard-water area, a stainless tub with a built-in water softener or rinse-aid dispenser is a practical investment that preserves the original efficiency rating for years.
Right-Sizing Capacity to Household
A twelve-setting machine run half-empty consumes more water and power per dish than a six-setting unit run full. Match the place-setting rating to your realistic daily dish volume, not your holiday maximum. Households of one or two typically find six to eight settings sufficient. Families of three to four benefit from a 24-inch machine if they cook at home most nights. The goal is one full cycle per day; if you regularly split loads, the efficiency advantage shrinks quickly.
Our Verdict
Top pick: The Honeywell 24-inch model earns the overall recommendation for the largest number of households because its twelve-place-setting capacity eliminates the efficiency-killing habit of running partial cycles, and its Energy Star rating plus seven-program range let you dial consumption down on lighter days.
Budget pick: The COMFEE’ Countertop at $278.95 is the cheapest path to a certified efficient dishwasher. For singles and couples who wash a few dishes each evening, it delivers the core benefit of the category without a full installation.
Conditional winner: If you rent or simply cannot modify plumbing, the NOVETE Portable is the only unit here that offers a standalone water-tank option, letting you run an efficient cycle in a kitchen where no other built-in or faucet-connected machine would be practical.
FAQ
Do portable countertop dishwashers really save energy compared to hand-washing?
Yes. Multiple independent analyses confirm that a full-load dishwasher cycle uses less water than running a tap continuously while washing by hand. The Energy Star models here add an electricity advantage on top of the water savings, especially in ECO mode.
What does the “place settings” number mean in practice?
A place setting roughly equals one dinner plate, one small plate, one bowl, one cup, and the matching utensils. Six settings cover one person’s full three-course meal plus a guest; twelve settings cover a family dinner with serving dishes. The number is a guideline, so pot and pan placement affects real capacity.
Is a stainless steel tub worth the price premium over plastic?
For most buyers yes. Stainless resists staining, does not absorb food odors, reflects radiant heat back onto dishes during drying, and maintains a more consistent spray-arm flow as years pass. The plastic-tub Honeywell is a rare exception where mixed construction keeps the price down while still offering full-size capacity.
Will an efficient dishwasher qualify for a utility rebate?
Many electric and water utilities offer rebates for Energy Star certified models. Because certification criteria tighten over time, units purchased in 2026 may qualify for programs that older stock did not. Check your local utility’s website before purchase to confirm the current rebate amount and eligible model list.
