Best Dishwashers in the US: Where to Buy, What to Choose, and How to Save

Why upgrading your dishwasher matters

Thinking about replacing that noisy, half-working dishwasher? You’re not alone. Upgrading to a modern dishwasher can cut your water bills, reduce kitchen noise, and actually save you time every week. Whether you rinse by hand or load right away, the right model changes your daily rhythm—like swapping a squeaky old bicycle for an electric one. You get more power, better cleaning, and often a slimmer footprint that fits your space.

Major retailers that carry dishwashers in the US

If you’re shopping for a dishwasher, you’ll see similar model lines across several major stores, each with different perks. Walmart often focuses on budget and portable options and even sells compact countertop units ideal for apartments. Home Depot and Lowe’s both offer full-size built-in models with installation services and a wide brand selection. Best Buy mixes big brands with smart-home integration and local delivery. Costco bundles value and extended warranties, and online specialists like AJ Madison and Appliances Connection give you deep inventory and expert help. Knowing what each retailer emphasizes helps you target the right place first.

Walmart: budget-friendly and portable choices

Walmart is a go-to for affordable, entry-level dishwashers and compact countertop models. If you live in a studio or rental, a portable countertop dishwasher with a small built-in water tank can be a lifesaver—no permanent plumbing needed. Walmart often lists mini dishwashers and unique gadgets designed for small loads, like dedicated teacup cleaners, which are handy if you collect delicate cups or glassware. Expect competitive pricing, frequent rollbacks, and a wide mix of brand-name and niche imports.

Home Depot: built-in units and professional install

At Home Depot you’ll find full-size built-in dishwashers from major appliance brands geared toward remodels and new kitchens. They’re strong on installation packages, local pickup, and pro installation scheduling—useful if you want the job done right in inches, not guesswork. Home Depot often stocks Energy Star-rated models with stainless steel tubs, quiet operation, and flexible rack systems, which are great if you want longevity and fewer service calls.

Lowe’s: price-matching and in-home services

Lowe’s competes closely with Home Depot on mid- to high-end models and frequently bundles installation and haul-away services. Their in-home measurement and installation options make replacing a built-in dishwasher less stressful. Lowe’s also runs seasonal promotions and offers financing options that spread the cost over several months, which can make a premium model feel much more affordable.

Best Buy and specialty appliance stores

Best Buy focuses on the tech-savvy shopper, offering integrated smart controls, Wi‑Fi connectivity, and local delivery. If you want voice control or push notifications about cycle status, Best Buy lists those features prominently. Specialty sites like AJ Madison and Appliances Connection are ideal when you want pro-grade brands, access to specialty finishes, or panel-ready models that blend into kitchen cabinetry. They often provide more SKU depth than big-box stores.

Types of dishwashers and which one fits your life

Dishwashers come in several flavors, and each has a use-case. Full-size built-in units handle a family’s worth of breakfast plates. Compact 18-inch models fit smaller homes. Countertop and portable dishwashers are perfect when plumbing options are limited. Drawer dishwashers offer ergonomic loading for tight kitchens. Pick the type that fits your space, how often you cook, and whether you need a permanent installation or a mobile solution.

Built-in full-size dishwashers: capacity and features

Built-in dishwashers are typically 24 inches wide and offer the best capacity and longest feature lists—think adjustable racks, third racks for cutlery, and stronger drying systems. If your home has a standard cabinet opening, a built-in model gives the cleanest look and the highest long-term value. They also tend to be quieter and more efficient in water usage per load, so if noise and efficiency matter, this is the category to prioritize.

Countertop and portable dishwashers: small but mighty

Countertop dishwashers sit on your counter and usually connect to the kitchen faucet; they’re perfect for renters or small kitchens where a 24-inch slot doesn’t exist. Portable wheeled dishwashers can roll to a sink and hook up when you need them. Modern portable models can use as little as a few gallons per cycle and still offer multiple washing programs. These are the models you’ll see in Walmart’s smaller appliance section and online marketplaces aimed at apartment dwellers.

Key features to compare before you buy

Don’t be swayed by sleek finishes alone—look under the lid. Important features include cycle variety, soil sensors, adjustable racks, third rack space, noise level, and tub material. Stainless steel tubs last longer and retain heat for better drying. Soil sensors adjust water and time based on how dirty your dishes are, saving energy and water. Adjustable tines and folding shelves add flexibility for pots and pans. Remember: the right combo of features beats a flashy finish every time.

Energy and water efficiency: gallons and cost savings

Water usage in dishwashers is measured in gallons per cycle, and modern efficient models often use under 4 gallons per load. Old machines can use 6 to 10 gallons or more, so switching can dramatically lower your water bill. Energy Star-rated models also reduce electricity use. If you’re watching utility costs, pick a model that lists both gallons per cycle and estimated annual energy consumption—the numbers will tell you which machine pays back the upfront cost over time.

Noise level, materials, and build quality

Quiet dishwashers are measured in decibels (dB); the lower the number, the quieter the machine. A quiet model—around 40 dB—won’t interrupt conversation and feels premium. Look for stainless steel tubs and thicker insulation; they cut noise and improve durability. Also check for solid hinge construction and heavy-duty spray arms—those small build-quality details mean fewer repairs years down the road.

Price ranges and where to find the best bargains

Expect to see several pricing bands: budget models under $400, solid mid-range units from $400 to $900, and premium models over $900. Big stores like Walmart and Target often hold the low-price end, while Home Depot, Lowe’s, and Best Buy cover mid-to-high range models. Costco can be a great place to pick up a quality unit with a bundled warranty for a little more peace of mind. Seasonal sales—Memorial Day, Black Friday, and Labor Day—are prime times to score steep discounts on even high-end models.

Financing, promotions, and price matching

Many retailers offer short-term financing or deferred-interest plans, which can spread the cost of a more expensive model into manageable monthly payments. Price matching is common at Home Depot and Lowe’s, so shop around and ask if they’ll match a competitor’s online price. Also watch for rebates and manufacturer promos that can cut the effective price further; stacking a store sale with a manufacturer rebate is how you get a premium machine at a mid-market price.

Installation, measuring, and plumbing basics

Installing a built-in dishwasher is a mix of carpentry and plumbing—measure twice and plan for access. Standard built-in units are usually 24 inches wide, about 34.5 inches tall without the countertop, and around 24 inches deep. Compact models are often 18 inches wide. If you’re replacing an old dishwasher, measure the opening width, height, and depth in inches and note where the water connection and drain hose sit. That’ll save you the “it won’t fit” panic at delivery time.

Measuring for replacement step-by-step

Start with the width of the cabinet opening in inches, then the height to the underside of the countertop. Measure depth from cabinet face to back wall. Check clearance for doors and nearby drawers. Note the location of electrical outlets and water valves. If you plan to install a panel-ready model, measure the cabinet door dimensions so it fits flush. Take pictures of the current plumbing and electrical layout—those images help installers avoid surprises.

Maintenance tips to keep your dishwasher running smoothly

Simple maintenance extends a dishwasher’s life. Clean the filter every few weeks, run a hot empty cycle with a dishwasher cleaner or a cup of white vinegar every month, and check spray arms for clogs. Use the correct detergent type and a rinse aid if your water is hard—this improves drying and reduces spotting. Address leaks and odd noises early; small problems rarely fix themselves and can turn into a hefty repair in a short time.

Troubleshooting common issues without calling a tech

If your dishwasher isn’t draining, check the filter and garbage disposal connection in inches for blockages or loose hoses. If dishes aren’t dry, ensure the rinse aid dispenser isn’t empty and the heating element isn’t blocked. Strange smells usually clear with a hot vinegar cycle and a wiped-down door gasket. For error codes, a quick search of the model number plus the code often yields straightforward fixes from manufacturer support pages or user forums.

Where to buy specialty units and unique accessories

Need a tea-cup-only cleaner or an ultra-compact countertop washer for delicate china? Besides big-box stores, look to online marketplaces and specialty retailers. Amazon lists many portable and niche devices with user reviews that hint at real-world performance. Specialty appliance stores and dedicated online shops have panel-ready or professional-grade models and can source uncommon accessories like custom racks, replacement spray arms, and OEM parts. If you own rare or high-value dishware, a more tailored solution from a specialty seller gives better long-term care.

Warranty and service considerations

Check manufacturer warranties for the tub and electronics. Many brands cover the motor and tub for one year, with longer warranties on stainless steel tubs. Retailer-provided extended warranties and installation packages can be worth it if you plan to stay in the home long-term. Keep your purchase receipts and model numbers handy—these details speed up any warranty service or parts replacement down the road.

Final shopping checklist

Before you click buy or sign a delivery invoice, run through a quick checklist: measure your opening in inches, decide between built-in versus portable, compare gallons per cycle and noise levels, confirm installation costs, and check for available promos or rebates. Think about how you load dishes now—do you use many pots and pans? If so, prioritize adjustable racks and high-temperature wash cycles. If you entertain often, a third rack for utensils can save loads of time.

Smart buying tips to save money and time

Compare prices across retailers, read user reviews for real-world reliability, and time your purchase around major holiday sales. Consider energy and water savings as part of the long-term cost, not just the sticker price. And if you’re unsure about installation, consider buying from a retailer that offers professional install and haul-away so you don’t end up dealing with old appliance removal on your own.

Conclusion

Buying a dishwasher doesn’t have to be overwhelming. Start with your space in inches, decide between portable or built-in, and choose features that match how you cook and clean. Shop retailers like Walmart for budget or portable solutions and Home Depot, Lowe’s, Best Buy, or specialty appliance stores for full-size and higher-end options. Watch for seasonal sales, compare gallons-per-cycle and noise ratings, and keep a maintenance routine to extend the life of your machine. A little planning up front gives you cleaner dishes, a quieter kitchen, and a smart investment that pays off every load.
